During this process, uneven element reactions can occur as lithium diffuses from the surface of the precursor inward. By doping lithium the ternary precursor, we achieve lithium-doped ternary precursors. This precursor enables uniform element diffusion during sintering, facilitating multi-element doping and reactions, which improves the rate performance of cathode materials. The introduction of lithium-doped ternary precursors provides strong support for innovation in cathode materials in the new energy industry.
