Surface Pinning of Mn by Oxidation State Control for the Synthesis of Cobalt-Free, Ni-Rich, Core/Shell Structured Cathode Materials (Small 31/2024)
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. In article number 2400518, Jin Ho Bang and co-workers.
