It uses metallic lead as the negative material, lead dioxide or lead oxide as the positive material, and sulfuric acid as the electrolyte. The voltage of lead-acid battery is usually two volts, so it is also commonly known as "electric battery".
    The working principle of lead-acid batteries is based on the chemical reaction between the positive and negative active materials and the electrolyte. During the discharge process, the positive and negative active substances react with sulfuric acid to produce lead sulfate and release electrical energy. And in the charging process, lead sulfate will be decomposed and reduced to sulfuric acid, lead and lead dioxide, to realize the battery recharge.Accord power is located in the world natural cultural heritage scenic area of Mount Huangshan's southern gate - Shexian County Recycling Economy Park, the company's factory is adjacent to the highway, high-speed rail, air, the transportation is convenient.

It is widely used in many fields such as automobile starting, electric power system, electric bicycle, communication equipment, industrial equipment, emergency lighting and solar energy storage, etc., providing stable and reliable electric power support for these equipments.

The history of lead-acid batteries can be traced back to the middle of the 19th century, and its development can be roughly divided into the following stages:

1, early R & D stage (1859-1881): In 1859, the French scientist Gravier (Gaston Planté) invented the lead-acid battery, which is the first rechargeable battery. It used lead plates as the positive and negative stages, separated by rubber, and sulfuric acid as the electrolyte, successfully realizing the interconversion between electrical energy and chemical energy. However, the initial version of the lead-acid battery had a very low specific energy due to the use of lead plates as electrodes.
2, technical improvement stage (1881 - 1950s): In 1881, the British physicist Ford (Camille Fauré) used the paste lead oxide technology, Pb3O4, distilled water and sulfuric acid made of lead paste coated on the surface of the lead plate, which substantially improved the specific energy of lead-acid batteries. In addition, the British Sellon (Sellon) invented a lead-antimony alloy plate grid, this grid and Fur powder coating method combined, the so-called paste-coated pole plate, this production method is simple and feasible, greatly facilitating the production.
3, space exploration to promote the stage (1950s -70s): the 1950s, the United States Bell Labs began to study the application of lead-acid batteries in space exploration, which promoted the technical progress of lead-acid batteries. By the 1970s, Japan, Germany and other countries began to invest heavily in the research and development of lead-acid batteries, and made a series of technological breakthroughs.
4, environmental protection and renewable energy application stage (21st century to the present): with the world's attention to environmental protection and renewable energy, lead-acid batteries are more and more widely used in solar energy, wind energy and other fields. At the same time, the lead-acid battery electrode materials, electrolyte and other aspects of technical progress, such as enhanced lead-acid batteries, gel electrolyte lead-acid batteries, identification batteries and other new types of lead-acid batteries continue to be developed.

    During the research and development of lead-acid batteries, newer test methods and instruments have been gradually introduced to study lead-acid batteries, such as SEM, TEM and DTA. During the 20 years from 1950 to 1970, the research on the basic theory of lead-acid batteries has made a significant leap, and its research focus has been shifted from thermodynamics to electrode process kinetics. In addition, developed countries have also invested a lot of manpower and material resources to develop sealed and maintenance-free lead-acid batteries, using low antimony and antimony-free Pb-Ca alloy to make the plate grid, in order to reduce water loss and self-discharge in the battery, so as to make lead-acid batteries in the process of use to achieve the requirements of low-maintenance and maintenance-free.

As a high energy density, high voltage rechargeable battery, Li-ion batteries are widely used in various portable electronic devices and electric vehicles. However, Li-ion batteries require precise control during charging and discharging to ensure safety and extend battery life. Protection boards (also known as protection circuits) are an important part of the safe use of lithium batteries, providing protection against overcharge, overdischarge, overcurrent and short circuit. The following is an exhaustive analysis of charging lithium batteries without protection plates.

The role of protection board
The protection board is a key component for the safe use of lithium batteries, and its main roles include:
1. Overcharge protection: prevent the battery charging voltage from exceeding the safety threshold, avoid damage to the positive electrode material and possible thermal runaway.
2. Over-discharge protection: preventing the battery discharge voltage from falling below the safety threshold, avoiding the damage of negative electrode material and the reduction of battery life.
3. Over-current protection: Limit the current through the battery to prevent damage caused by excessive current.
4. Short-circuit protection: Cut off the current when an external short circuit is detected, preventing the battery from overheating and possible thermal runaway.

Risks of charging without a protective plate
1. Overcharge Risk: Without overcharge protection, the battery may be charged beyond its maximum safe voltage, resulting in overheating, expansion or even explosion.
2. Over-discharge risk: Without over-discharge protection, the battery may be discharged to too low a voltage, damaging the negative electrode material and reducing battery life.
3. Overcurrent Risk: When charging or discharging at high current, the lack of overcurrent protection may cause the battery to overheat and damage the battery structure.
4. Short-circuit risk: Without short-circuit protection, the battery may generate a large amount of heat in case of external short-circuit, causing combustion or explosion.

Charging lithium batteries directly without protection boards is a very risky behavior. Lithium battery protection plate is an important component of lithium battery, its main functions include overcharge protection, overdischarge protection, short-circuit protection, temperature protection and equalization of charge and discharge. These protection mechanisms ensure the safety and stability of lithium batteries in the process of use.

First of all, overcharge protection is one of the core functions of lithium battery protection board. When the voltage of the lithium battery exceeds the set value during charging, the protection board will cut off the external power supply to prevent the battery from continuing to charge, in order to avoid overcharging resulting in battery performance degradation, safety risks and shortened life. Without the protection board, the lithium battery may continue to charge until the voltage is too high, which may cause a safety accident.

Secondly, over-discharge protection is also an important function of the protection board. When the voltage of lithium battery is lower than the set value during discharge, the protection plate will cut off the connection between the battery and the load, preventing the battery from continuing to discharge, and avoiding the over-discharge that causes excessive battery loss, capacity decline, and the inability to recover and other problems. Lithium batteries without protection boards may be over-discharged during the discharge process, resulting in battery damage or even causing safety accidents.

In addition, short circuit protection is also one of the important functions of the protection board. When the lithium battery is short-circuited, the protection plate will quickly cut off the output of the battery and prevent the excessive current from causing thermal runaway, fire or explosion inside the battery. Lithium batteries without protection boards may have serious accidents when short-circuited.

Finally, the equalization charging and discharging function is especially important for lithium battery packs. Li-ion battery packs consist of multiple individual cells, each of which may have different characteristics. The protection board can detect the over-voltage, under-voltage, over-current, short-circuit and over-temperature status of each single cell in the battery pack, and extend the service life of the battery by equalizing charging and discharging. Lithium battery packs without protection boards may have inconsistent performance of individual cells, affecting the performance and life of the entire battery pack.

To summarize, there is a great safety risk in charging lithium batteries directly without protection plates. In order to protect the safety and stability of lithium batteries, it is recommended to use lithium batteries with protection plates and ensure that the relevant safety norms are observed during use and charging.

Lithium phosphate batteries are related to blade batteries in nature, but they are not exactly equivalent. Lithium phosphate batteries, or LFP batteries for short, are a kind of secondary batteries, which use lithium iron phosphate and graphite as the main positive and negative materials, and organic solvents and salts as the electrolyte. This type of battery is characterized by high energy density, long life, better safety performance and environmental protection. The energy density of lithium phosphate battery reaches more than 200Wh/kg, and its service life can reach more than 2,000 times, which can meet the needs of long-term use. In addition, compared with other lithium-ion batteries, lithium phosphate batteries are less likely to be overcharged or short-circuited during charging, providing better safety. The blade battery, on the other hand, is a new type of battery product released by BYD in 2020.

Lithium iron phosphate batteries and blade batteries are two related but different concepts. A lithium iron phosphate battery is a type of lithium ion battery that uses lithium iron phosphate as the cathode material, while a blade battery is a battery product developed by BYD that utilizes lithium iron phosphate technology and has a different design and structure than the traditional lithium iron phosphate battery.

Lithium iron phosphate battery
Lithium iron phosphate batteries are favored by the market due to their good thermal stability, long life and cost-effectiveness. They usually have a high level of safety because the lithium iron phosphate material is more stable at high temperatures and has a lower risk of thermal runaway. In addition, Li-FePO4 batteries have a longer lifespan, can withstand more charge/discharge cycles, and have a relatively low cost, properties that make them very popular in many applications.

Blade Battery
Blade batteries are a new battery technology introduced by BYD, based on lithium iron phosphate battery technology. Blade batteries are designed with long, strip-shaped cells, a design that helps to improve the space utilization of the battery pack, thereby increasing the energy density of the battery. Compared to traditional lithium iron phosphate batteries, blade batteries offer a significant increase in volumetric energy density, which is particularly important for electric vehicles as they can provide longer range.

 The battery adopts lithium iron phosphate technology and is characterized by super safety, super strength, super range and super life. Through structural innovation, the blade battery can skip the "module" when forming a group, which greatly improves the volume utilization rate, and ultimately achieves the design goal of loading more cells in the same space. In addition, the blade battery also passed the "Mount Everest" in the field of battery safety testing - pin prick test, and successfully challenged the extreme strength test - 46 tons of heavy truck crushing test, proving its superior performance. This proves its superior performance. In terms of their definitions and characteristics, lithium phosphate batteries and blade batteries both use lithium iron phosphate technology, so they have certain similarities. However, the blade battery is not simply a lithium phosphate battery, but through the innovation and optimization of the battery structure, to achieve higher energy density and better performance. In addition, blade batteries have undergone rigorous testing and validation, proving their superiority in terms of safety, strength, range and life. Therefore, although both lithium phosphate and blade batteries utilize lithium iron phosphate technology, there are some differences between them in terms of structure, performance and application. Blade batteries are a new type of battery product based on BYD's innovation and optimization of lithium iron phosphate technology, with higher energy density and better performance.

There are various reasons for the voltage drop of lead-acid batteries after being fully charged, and these reasons cover a variety of aspects such as changes in the internal chemical reaction of the battery, the aging of the battery structure, and the conditions of use. First of all, sulfation is one of the important reasons. Long-term undercharging or over-discharging may lead to internal battery sulfation, i.e., the overgrowth of lead sulfate crystals on the negative plate. This overgrowth of lead sulfate crystals increases the internal resistance of the battery, resulting in a voltage drop. Sulfation is a common phenomenon during battery use, especially if charging is not timely after discharge. Secondly, plate grid corrosion is also a cause of voltage drop. Plate grid corrosion is the process of dissolving the material of lead on the negative plate into the electrolyte in lead-acid batteries.

The phenomenon of lead-acid battery voltage dropping fast when the battery is fully charged and left unused may be caused by a variety of factors, including self-discharge of the battery, chemical and physical changes within the battery, and environmental conditions. The following is a detailed analysis of this phenomenon.
The charging and discharging process of lead-acid batteries involves complex electrochemical reactions. When charging, the positive plate (anode) is converted from lead dioxide to lead sulfate, and the negative plate (cathode) is converted from spongy lead to lead sulfate as well. When discharged, these reactions are reversed, and the lead sulfate is again converted to lead dioxide and spongy lead.

[Self-discharge phenomenon]
1. Self-discharge : All batteries undergo self-discharge, i.e., even if the battery is not connected to any load, its charge will naturally decrease over time. The self-discharge of lead-acid batteries is usually more significant than that of other types of batteries, such as lithium batteries.
2. Chemical reaction: The self-discharge of lead-acid battery is partly caused by the internal chemical reaction, even if the battery is not working, the active substances on the positive and negative plates will react with the sulfuric acid in the electrolyte.
3. Evaporation of electrolyte: Evaporation of electrolyte can also lead to self-discharge, because the concentration of electrolyte will change after water evaporation, which will affect the voltage of the battery.

 This corrosion leads to the loss of active material, which reduces the capacity and voltage of the battery. With the growth of battery use time, the degree of plate grid corrosion will gradually increase, resulting in a faster rate of voltage drop. In addition, active substance shedding also affects the voltage. With the charging and discharging cycles, the active material on the positive and negative plates may gradually fall off. This shedding reduces the capacity of the battery, which in turn affects the voltage. The speed and degree of shedding of active material is related to the battery's operating conditions, charging and discharging methods and other factors. In addition to the above internal factors, external factors may also lead to a drop in voltage after the lead-acid battery is fully charged. For example, the impurity content of a new battery exceeds the standard may affect the performance of the battery.
   The content of lead in the raw material of pole plate, the pollution in the production process, the quality of electrolyte and the dust, lead particles and lead slag in the assembly process may affect the performance and voltage of the battery. In addition, internal leakage, wet electrolyte between the poles of the battery, external leakage and the old battery aging serious, very small capacity, no storage and other factors may also lead to voltage drop. To summarize, there are various reasons for voltage drop after lead-acid battery is fully charged, and it is necessary to comprehensively consider the internal structure of the battery, the chemical reaction, the use of conditions and external factors and other aspects. In order to reduce the speed and degree of voltage drop, it is necessary to take appropriate charging and discharging methods, regular maintenance of the battery, avoid overcharging and over-discharging and other measures.

Lead-acid batteries, also known as secondary batteries, rechargeable batteries, rechargeable batteries and primary batteries, are devices capable of converting chemical energy directly into electrical energy. Its core construction consists of metallic lead as the electrode, and manganese dioxide or nickel sulphate as the positive active substance. The electrolyte, on the other hand, consists of an aqueous solution of sulphuric acid. In the discharge state, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead; while in the charging state, the main component of the positive and negative electrodes are both lead sulphate.
Lead acid type batteries are composed of electrodes made from lead, an electrolyte solution containing sulphuric acid, and a separator material to prevent the electrodes from coming into direct contact. The lead electrodes are typically grid structures, with the positive electrode (cathode) containing lead dioxide and the negative electrode (anode) containing pure lead or lead antimony. The lead acid battery has a nominal voltage of 2V, although multiple cells can be connected in series to achieve higher voltage levels. These batteries have a wide operating temperature range, typically from -20°C to 40°C, which makes them suitable for various climatic conditions.
Lead-acid batteries have a variety of specifications, and their capacity is usually expressed in terms of the unit of ampere-hour (Ah). Common lead-acid batteries include 6V series and 12V series.The specifications of 6V series batteries include 4.5Ah, 7Ah, 12Ah, 20Ah, 35Ah, 100Ah, 150Ah and so on. Each size has its own specific dimensions, for example, a 4.5Ah battery measures 70mm x 47mm x 101mm, while a 150Ah battery measures 484mm x 171mm x 241mm.These batteries are suitable for use in a variety of small electronic devices such as security systems, small UPSs and emergency lighting.The 12V series of batteries are more common, with sizes including 1.2Ah, 4Ah, 7Ah, 18Ah, 28Ah, 45Ah, 90Ah, 120Ah, and more. The dimensions of these batteries vary depending on the capacity, such as the 1.2Ah battery with dimensions of 97mm x 43mm x 52mm. 12V lead-acid batteries are widely used in solar energy systems, electric vehicles, UPS systems, and other applications that require longer standby power times due to their higher voltage and diverse capacity options.
When choosing a lead-acid battery, in addition to considering its capacity and specifications, you also need to pay attention to factors such as its life, discharge characteristics, weight and charging time. For example, the life of a battery will have a direct impact on its cost of use, while the discharge characteristics determine the performance of the battery under different conditions of use. In addition, weight is also a factor to consider, especially in applications that require mobility or portability. The charging time, on the other hand, is related to the battery's charging efficiency and ease of use.In addition, lead-acid batteries are categorised in quite a variety of ways. For example, valve-regulated sealed maintenance-free battery is a typical type of lead-acid battery, which consists of two single cells, one for the negative plate and the other for the positive plate. This type of battery does not require frequent maintenance during use, reducing operating costs for the user.
However, despite its wide range of applications and multiple advantages, the lead-acid battery has some inherent disadvantages, such as a relatively high self-discharge rate and low energy density. These problems limit the application of lead-acid batteries in some specific areas to a certain extent.In general, lead-acid batteries, as an important power supply equipment, have a variety of specifications and different performance. When choosing and using them, they need to be considered comprehensively according to the actual needs and conditions in order to achieve the best results.

Lead-acid batteries are a common type of battery, widely used in automobiles, electric vehicles, UPS power supplies and other fields. In order to ensure that lead-acid batteries can operate stably for a long time and prolong their service life, the correct charging method is crucial. The charging method of lead-acid batteries will be described in detail below.
Accord Battery believes that understanding the working principle of lead-acid batteries is the basis for proper charging. Lead-acid batteries produce electrical energy through a chemical reaction between the internal anode (PbO2) and cathode (Pb) and an electrolyte (dilute sulfuric acid). The charging process is the reverse of this chemical reaction, i.e., an external power source provides electrical energy to the battery, restoring the active substances at the anode and cathode to their original state.

Next, regarding the charging of lead-acid batteries, we need to pay attention to the following key aspects:
Timing of charging: the best time to charge a lead-acid battery is usually when the charge is depleted to about one-third of its remaining capacity. This ensures that the battery is not over-discharged, which can affect its service life. It is also important to avoid charging the battery after it has been completely depleted, as this may cause damage to the battery.
Charging environment: The charging environment should be kept dry and tidy to avoid moisture and dust causing damage to the battery and charger. In addition, the charger should avoid being wrapped in a plastic bag or bottle, as the lack of air permeability may cause the charger to overheat or even burn out.
Charging method: It is recommended to use a standard charger for charging and follow the correct charging procedure. Firstly, plug the connected battery into the charger and then switch on the AC power. When charging is complete, disconnect the AC power supply and then unplug the plug connected to the battery. This ensures a safe and effective charging process.
Charging voltage and current: The charging voltage and charging current of the charger should be consistent with the parameters of the battery being charged to ensure charging effectiveness and battery safety. Too high a voltage or current may cause damage to the battery, while too low a voltage or current may result in undercharging or too long a charging time.
Avoid fast charging: Although fast charging technology can charge the battery with a large amount of electricity in a short period of time, frequent use of fast charging may cause damage to the lead-acid battery. Therefore, it is recommended that fast charging be avoided except when necessary and no more than twice in a month.
Regular maintenance: Lead-acid batteries require regular maintenance, including checking the electrolyte level and cleaning the battery surface. If the battery is not used for a long period of time, supplemental charging should be performed at regular intervals to prevent the battery from self-discharging and leading to depletion of power.

There are also some considerations about charging lead-acid batteries:
Lead-acid batteries do not have special requirements for initial charging time and charging volume, and can be charged and discharged at any time, which will not lead to the pole plate memory effect.
Overcharging and overdischarging should be avoided. Overcharging will lead to thinning of the metal layer of the plate grid, which is easy to fracture; over-discharge will lead to sulfation of the electrode plate, failure of the active sponge organisation and shorten the service life of the battery.
When using lead-acid batteries, the specific gravity of the electrolyte and the height of the liquid level of the battery should be checked regularly to ensure that the electrolyte is not missing.
In summary, the charging method of lead-acid batteries involves many aspects, including charging timing, charging environment, charging method, charging voltage and current, avoiding fast charging and regular maintenance.

Существуют различные причины недостаточного 24-часового времени резервного питания для
UPS (источников бесперебойного питания). Во-первых, ключевым фактором, влияющим на время работы в режиме ожидания, является производительность и качество самой батареи. Если батарея стареет, повреждена или имеет недостаточную емкость, ее способность к питанию естественным образом снижается, что приводит к сокращению времени работы в режиме ожидания. Во-вторых, нагрузка на систему ИБП также является важным фактором, влияющим на время работы в режиме ожидания. Если нагрузка слишком велика, батарея должна обеспечивать больше энергии для поддержки работы системы, что приведет к потреблению большего количества энергии и, следовательно, к сокращению времени ожидания. Кроме того, факторы окружающей среды, такие как температура и влажность, также могут влиять на производительность и срок службы батареи, что, в свою очередь, сказывается на времени работы в режиме ожидания. Наконец, конструкция и конфигурация системы ИБП также могут влиять на время работы в режиме ожидания. Если система спроектирована или сконфигурирована неправильно, это может привести к тому, что батареи не смогут в полной мере использовать свои возможности, что скажется на времени работы в режиме ожидания. Поэтому, чтобы система ИБП обеспечивала достаточное время работы в режиме ожидания, необходимо выбирать батареи с хорошими характеристиками и надежным качеством, а также разумно настраивать и использовать систему ИБП. В то же время очень важно регулярно проверять и обслуживать батареи. {Источник бесперебойного питания (ИБП) - это силовая электронная система, содержащая накопитель энергии (обычно батареи), основной функцией которой является обеспечение непрерывного и стабильного питания критически важного оборудования за счет внутреннего накопителя энергии в случае перебоев в подаче основного питания. Многие пользователи нуждаются в длительном резервном питании от батарей, особенно в районах с нестабильным электроснабжением, и ожидают, что ИБП сможет обеспечивать поддержку в течение как минимум 24 часов в случае перебоев в электроснабжении. Однако иногда пользователи сталкиваются с тем, что реальное время работы в режиме ожидания значительно отстает от ожиданий. В этой статье мы подробно разберем распространенные причины недостаточного 24-часового времени резервного питания ИБП.

В некоторых случаях из-за недостаточного понимания системы ИБП ожидаемое пользователем время работы в режиме ожидания может выходить за пределы фактического расчетного диапазона изделия. Причинами такого несоответствия могут быть завышенные ожидания, неправильное толкование технических характеристик изделия или ошибки в расчетах нагрузки. Пользователи должны иметь четкое представление о параметрах работы оборудования ИБП и делать разумный выбор, исходя из реальных потребностей. Перед покупкой следует проконсультироваться со специалистами и провести детальную оценку нагрузки и планирование мощности в соответствии с реальной ситуацией.

На самом деле, причиной недостаточного времени работы ИБП от резервной батареи часто является сочетание факторов. Например, деградация батареи и проблемы с системой зарядки могут сосуществовать, или факторы окружающей среды и плохие привычки использования могут вместе влиять на срок службы батареи. Для того чтобы система ИБП обеспечивала достаточное время работы в режиме ожидания, каждый из вышеперечисленных факторов необходимо тщательно изучать и отслеживать в режиме реального времени. Время работы системы ИБП в режиме резервного копирования можно увеличить за счет регулярных проверок системы, замены устаревших батарей, поддержания подходящих условий окружающей среды и разумного планирования будущих потребностей в электроэнергии.
