Introduction Lithium-ion batteries are accompanied by volume expansion, including structural expansion and gas production expansion, during the process of formation, cycling, storage, and overcharging. The charge-discharge rate determines the rate of the lithium-deintercalation reaction of the battery cell, and it is also accompanied by different degrees of heat generation or lithium evolution. When researchers study …
