中国锂离子电池系统钴代谢分析
Cobalt flow analysis of lithium-ion battery system in China
摘要
Abstract
By implementing the method of substance flow analysis,cobalt flow analysis model of lithium-ion battery system was developed based on the cobalt substance flow diagram of lithium-ion battery system in its life cycle,the relationship between lithium-ion battery system and its external environment was established and the elementary rules of cobalt substance flow in lithium-ion battery system were obtained.The resource efficiency and environment efficiency of cobalt were chosen as the evaluation parameters of cobalt flow state in the lithium-ion battery system in 2012 with statistics,literatures and interviews.The results indicate that the resource efficiency and environment efficiency of cobalt in lithium-ion battery system are 1.185 t/t and 2.749 t/t respectively.Improving the cobalt cycle rate and decreasing the cobalt discharge rate are efficient ways to increase the resources efficiency and environment efficiency of cobalt in lithium-ion battery system.关键词
