A review on the key issues of the lithium ion battery degradation among the whole life cycle

The lithium ion battery is widely used in electric vehicles (EV). The battery degradation is the key scientific problem in battery research. The battery aging limits its energy storage and power output capability, as well as the performance of the EV including the cost and life span. Therefore, a comprehensive review on the key issues of the battery degradation among the whole life cycle is provided in this paper. Firstly, the battery internal...
