摘要
Abstract
Li-ion battery was an environment friendly new power source,but the difficulty of charging at a subzero temperature was an obstacle for the development.20％ soft carbon was added into MCMB,and analyzed the charging,discharging and cycle life performance at low temperature were analyzed.As a result,with 20％ percentage of soft carbon added,charging at-10 ℃ and-20 ℃,compared with 25 ℃,the total charging capacity is 91.11％ and 81.74％;cycle at-20 ℃ for 50 times,the residual capacity is about 91.91％ of the first cycle.关键词
