Review of Research Progress on Positive Electrode Materials for Manganese-Based Lithium-ion Batteries
This article reviews four types of manganese-based cathode materials corresponding to lithium-rich manganese-based batteries,lithium manganese oxide batteries,nickel-cobalt-manganese oxide batteries,and lithium manganese iron phosphate batteries.The advantages and disadvantages of these four cathode materials are analyzed,and methods for improving material performance,including doping,coating,calcination temperature adjustment,and oxygen vacancy adjustment,are introduced.This provides an analysis for the development of positive electrode materials for manganese-based lithium-ion batteries,especially in terms of modification strategies to improve energy density,cycle stability,and safety.It is hoped to provide relevant references for the application of manganese-based lithium-ion batteries in the field of new energy through continuous innovation and optimization of materials.
