In recent years, as environmental pollution has increased, countries have paid more and more attention to the development of clean energy and renewable energy. As an important technical support for improving the stability of renewable energy, energy storage has also ushered in considerable development.
Lead-carbon battery is an advanced technology battery evolved from traditional lead-acid batteries. The reason why it is called "advanced" is that lead-carbon batteries combine lead-acid batteries and supercapacitors into one. In terms of technology that takes advantage of the short-time and large-capacity charging characteristics of supercapacitors, it maintains the advantage of high specific energy of lead batteries. Thereby it has good charge and discharge performance and long service life. In addition to performance advantages, lead-carbon batteries also have obvious advantages in cycle life, cost performance, safety, low temperature performance, production and recycling processes.
The porous carbon in the negative plate of the lead-carbon battery and the lead active material produce a synergistic effect, which significantly improves the specific surface area and stability of the electrode plate, thereby improving the battery cycle life and charge and discharge capabilities. Therefore, in-depth research on the mechanism of carbon materials in lead-carbon batteries will further enhance the performance of lead-carbon batteries. In the future, in-depth research and application development of high-performance carbon materials will still be the focus of related research work, which will further improve the performance of lead-carbon batteries and realize their large-scale applications in fields such as energy storage.
