Paradoxical Role of Structural Degradation in Battery Performance

【Research Background】 The performance decay of lithium-ion batteries (LIBs) is influenced by both cycling and storage. The performance decay caused by cycling is primarily due to the chemical-mechanical degradation of active materials, which has been extensively studied. However, the mechanisms of performance decay due to storage differ from those due to cycling, and research on … Read more
