Cathode Materials Calcination of Ni-rich core/Mn-rich shell precursors with a pre-oxidized Mn component demonstrably suppresses Mn interdiffusion. This preservation of the core/shell architecture minimizes surface Ni content, thereby enhancing interfacial stability. Consequently, the core/shell design significantly mitigates surface-induced side reactions and cross-talk effects, leading to reduced growth of interfacial impedance during battery operation.
