    There is a picture showing the degradation mechanisms and various interplaying factors within a Li-ion cell. The aging mechanisms are complicated and a lot of things can happen at the same time, or lead to one another.

    Taking the battery capacity decay as an example, this phenomenon could be related to various microscopic behaviors, such as changes in the structure of the positive electrode, dissolution of the surface transition metal, an increase in the positive electrode solid electrolyte layer (SEI), an increase in the negative electrode solid electrolyte layer, and decomposition of the electrolyte...
