Exploring the Aging Dynamics of Lithium-Ion Batteries for Enhanced Lifespan Understanding

This review examines the aging mechanisms and performance decline of
lithium-ion batteries under various conditions, focusing on temperature effects, charge/discharge efficiency, and operational limits. It covers high-temperature aging and its impact on the solid electrolyte interphase (SEI) layer, as well as thermal runaway risks. Low-temperature aging is also discussed, emphasizing reversible capacity loss, increased resistance, and lithium plating. The review addresses degradation from overcharge/overdischarge scenarios and explores coulombic efficiency (CE) degradation and its link to capacity loss. By synthesizing current research, it provides insights into optimizing battery management and enhancing performance.
