退役三元18650电池的性能测试
Performance evaluation of retired 18650 ternary lithium-ion power batteries
摘要
Abstract
With the retired 18650 ternary lithium-ion power batteries as research objects,the residual capacities of the batteries were analyzed under the condition of GB/T 34015-2017,the cycle life and cycle discharge characteristics of the batteries were studied,and the safety performances were tested under the condition of GB/T 40165-2021.The results show that the residual capacities of the batteries are in the range of about 63％-80％of the rated capacity.The discharge capacity and cycle life of re-tired batteries are related to the rate.The cycle life of retired batteries increases significantly at low current rates,and when the residual capacity of retired batteries is lower than 75％of the rated ca-pacity,their cycle performance decreases significantly.The residual capacity of retired battery cells is between 75％and 80％,with no significant difference in cycle life,and can demonstrate good safety performance through multiple safety tests.关键词
