锂电池负极包覆材料Coating material for graphite based anode of Lithium-ion batteries

新能源产业快速发展带动储能需求，新型储能中锂电池储能技术趋近成熟，占据主导路线。表面包覆工艺能有效提高负极石墨材料的循环稳定性和可逆容量，有效抑制剥离现象。The main material used for the anode of lithium-ion batteries is graphite. Graphite anode is prone to form SEI, which has an adverse effect on the performance of the battery. Our pitch-based coating material can improve the charging efficiency and cycling performance of the batteries.
