Transition Metal Dissolution refers to the phenomenon that during battery operation or storage, transition metal elements (such as Mn, Ni, Co, Fe, etc.) in the positive electrode material are separated from the positive electrode, enter the electrolyte and may migrate to the surface of the negative electrode.
This is an irreversible degradation reaction that usually occurs under conditions of high temperature, high voltage, or side reactions between the electrolyte and the positive electrode material.
