Quantitative Analysis of the Coupled Mechanisms of Lithium Plating, SEI Growth, and Electrolyte Decomposition in Fast Charging Battery Lithium ion battery (LIBs) degradation under fast-charging conditions limits its performance, yet systematic and quantitative studies of its mechanisms are still lacking.
Cycling degradation in lithium-ion batteries refers to the progressive deterioration in performance that occurs as the battery undergoes repeated charge and discharge cycles during its operational life . With each cycle, various physical and chemical processes contribute to the gradual degradation of the battery components .
Degradation mechanism of lithium-ion battery . Battery degradation significantly impacts energy storage systems, compromising their efficiency and reliability over time . As batteries degrade, their capacity to store and deliver energy diminishes, resulting in reduced overall energy storage capabilities.
