The Influence of Carbon Material on the Low-Temperature Performance of Lead-Acid Battery

Storage battery is an indispensable energy storage device at present. It is widely applied to industries like electric automobiles due to its advantages such as safety, reliability, low cost, etc. However, like most storage batteries, lead-acid battery has a series of problems in the low temperature environment such as the plunge of capacity, difficulty of charge, and so on, which deeply influence its application effect. To improve the low temperature performance of lead-acid battery, carbon materials could be added to the cathode of lead-acid battery. By measuring the properties like HRPSoC cycle and dynamic charging under different carbon (graphite) content, this article concludes that the addition of carbon material could improve the low-temperature performance of lead-acid battery. When the carbon content is between 0.3% and 0.9%, the improvement effect is relatively better. The research result of this article has a reference function to the design and development of low-temperature lead-acid batteries.
