Recent progress in synthesis and surface modification of nickel-rich layered oxide cathode materials for lithium-ion batteries

Abstract Nickel-rich layered oxides have been identified as the most promising commercial cathode materials for lithium-ion batteries (LIBs) their high theoretical specific capacity. However, poor cycling stability of nickel-rich is one major barriers large-scale usage LIBs. The existing obstructions that suppress capacity degradation are a result phase transition, mechanical instability, intergranular cracks, side reaction, oxygen loss, and thermal instability during cycling. Core–shell structures, oxidating precursors, electrolyte additives, doping/coating synthesizing single crystals effective methods to improve materials. Herein, recent progress surface modification, e.g. coating doping, in summarized based on Periodic table provide clear understanding. Electrochemical performances mechanisms modified structure discussed detail. It hoped an overview synthesis modification can be presented perspective LIBs given.
