Lead-acid battery is a kind of common storage battery, Accord power on the lead-acid battery in recent times to the current technical development in the past 10 years to make a technical development of change observation and analysis. Since the birth of lead-acid batteries, after nearly two centuries of development, the technology has been continuously improved and perfected, and the field of application has become increasingly wide. From modern times to modern times, the development of lead-acid battery technology has changed significantly, mainly reflected in the manufacturing process, material formulations, performance enhancement and environmental performance improvement.
Lead-acid battery technology is an important part of the development of the battery industry, which is related to the improvement of battery performance, cost reduction and environmental protection. In recent years, with the continuous progress of science and technology and the growing demand for applications, lead-acid battery technology has achieved significant results in updating and iteration. First of all, lead-acid batteries have made a lot of innovations in electrode materials. The traditional lead-acid battery electrode material is based on pure lead, but its specific energy is low and the self-discharge rate is high. To overcome these problems, researchers began to explore new electrode materials. For example, by adding carbon materials with high specific surface, such as activated carbon and activated carbon fiber, to the lead negative electrode, the utilization rate of lead active material can be improved and the growth of lead sulfate crystals can be inhibited. The application of this lead-carbon technology has led to a significant improvement in the energy density and cycle life of lead-acid batteries.
In the mid-19th century, French scientist Gaston Planté invented the lead-acid battery, which is considered the first rechargeable battery. It used lead plates as the positive and negative electrodes, separated by rubber, and sulfuric acid as the electrolyte, realizing the interconversion between electrical energy and chemical energy. This laid the foundation for the subsequent development of lead-acid battery technology. Subsequently, Camille Fauré improved the lead-acid battery by applying lead paste made of Pb3O4, distilled water and sulfuric acid to the surface of lead plates for the first time, which improved the specific energy of the lead-acid battery. This improvement makes the structure of lead-acid battery basic molding and maturity, for the subsequent application provides a possibility.
In the 20th century, the
lead-acid battery technology was further improved. 1957, West Germany Sunshine Company applied gel electrolyte technology to lead-acid batteries, realized the fixation of electrolyte, and made sealed lead-acid batteries (gel batteries). This technological breakthrough greatly improved the reliability and safety of lead-acid batteries, providing the possibility of their application in more fields.
Secondly, lead-acid batteries are also optimized in the battery structure. The traditional lead-acid battery structure is relatively simple, but with the improvement of application requirements, people began to explore more complex structure. For example, the emergence of three-dimensional and double three-dimensional structure electrodes and new structures such as fully sealed, tubular, horizontal, etc., makes the lead-acid battery in the capacity, charging speed and safety have been improved. Meanwhile, the use of new lead alloy electrodes has further contributed to the improvement of specific energy and the extension of service life. In addition, the production process of lead-acid batteries has also been improved. The traditional lead-acid battery production process is cumbersome and prone to environmental pollution. In order to reduce production costs and environmental pollution, researchers have begun to explore more environmentally friendly and efficient production processes. For example, lead-acid batteries designed with colloidal electrolytes have the advantages of high thermal capacity, low temperature rise and longer life expectancy. This design not only improves the performance of the battery, but also reduces environmental pollution in the production process.
In terms of application areas, Accord power believes that the updated iteration of lead-acid battery technology also brings a broader market space. With the booming of the electric vehicle market, the demand for lead-acid batteries continues to increase. Although the current share of lithium batteries in the field of electric vehicles is growing rapidly, lead-acid batteries still have the advantages of cheaper prices, higher charging and discharging efficiencies, and for some electric vehicle manufacturers, lead-acid batteries can provide more stable performance and reliability. In addition, lead-acid batteries have a wide range of applications in the energy storage market. With the popularization of renewable energy and the development of power network, energy storage technology has gradually become an important means to solve the problems of unstable energy supply and power peaking. As a mature and stable energy storage technology, lead-acid batteries will play an increasingly important role in the energy storage market.
With the development of science and technology, the manufacturing process and material formulation of lead-acid batteries have been continuously improved. By optimizing the material ratio and adopting new production processes, the cycle life of lead-acid batteries has been significantly extended, the charging efficiency has been improved and the self-discharge rate has been reduced. This makes lead-acid batteries more reliable and long-lasting, and can meet the needs of more application scenarios. At the same time, the environmental performance of lead-acid batteries has been gradually improved. With the improvement of environmental awareness, manufacturers began to research and develop more environmentally friendly lead-acid batteries. They adopt lead-free technology to reduce pollution to the environment. In addition, the technology of recycling and reusing lead-acid batteries has also been upgraded, further reducing the impact on the environment. This has led to significant progress in the sustainability of lead-acid batteries.
In addition to performance enhancement and improved environmental performance, the application scope of lead-acid batteries is also expanding. Traditional applications such as automotive, UPS power supply, electric vehicles, etc., are still the main market for lead-acid batteries. With the development of technology and changes in market demand, lead-acid batteries are also widely used in solar energy storage systems, communication base stations, power grid peaking and other fields. These new applications provide a broader space for the development of lead-acid batteries.
As a technology company, Accord power always believes that the development of new battery technology is essential for contemporary mankind in the field of energy technology research, however, lead-acid battery technology is still facing some challenges. For example, how to further improve its energy density and cycle life, reduce production costs and environmental pollution and other issues still need in-depth research. In addition, with the rapid development of new energy vehicles and energy storage market, the competition between lead-acid batteries and other types of batteries, such as lithium batteries, has become increasingly fierce. Therefore, lead-acid battery technology needs continuous innovation and breakthroughs to adapt to the changes in market demand. The updating and iteration of lead-acid battery technology is an important direction for the development of the battery industry. Through the innovation of electrode materials, optimization of battery structure and improvement of production process, the performance of lead-acid batteries has been significantly improved and the application areas have been expanded.
