Abstract: High-nickel cathode materials have advantages such as high capacity, low cost, and environmental friendliness, and are regarded as the most potential cathode materials in the future field of lithium-ion batteries. However, in practical commercial applications, their performance is restricted by multiple factors such as excessive residues of lithium-ion compounds, insufficient structural stability, and limited rate performance. Doping modification of high-nickel cathode materials, as an effective solution, has received extensive research. Based on the high energy density and high cycling performance of high-nickel materials, an analysis and summary of the doping modification of lithium-ion battery cathode materials has been carried out, and the current challenges of high-nickel cathodes are sorted out and the future development directions are prospected. The aim is to provide a useful reference for the performance improvement of lithium-ion battery high-nickel cathode materials, and further lay a solid theoretical foundation for the development of high-nickel cathode materials in the energy industry in terms of cycling and stability.
