Study on the Mechanism of Cycle and Storage Process of Lithium-Ion Battery

Abstract

The changes of battery performance, crystal structure, fine structure and microstructure of positive and negative active materials in the processes of cycle and storage of lithium-ion battery were studied experimentally, and the change of battery performance was related to the structure change of positive and negative active materials. The mechanism of cycle and storage process was revealed, and the attenuation mechanism of battery cycle performance and storage performance was discussed. The method and action mechanism of improving cycle-storage performance are introduced.
