全固态硫化物锂电池中NCM正极及其界面研究
A review of NCM cathode and interface characteristics in all-solid-state lithium-ion battery with sulfide electrolytes
摘要
Abstract
All-solid-state lithium-ion battery(ASSLB)with sulfide electrolyte is regarded as the most effective solution to the safety problems and energy density improvement of traditional liquid lithium-ion batteries.The cathode material largely determines the basic performance of all-solid-state lithium-ion batteries,as one of the main part of lithium-ion batteries.The NCM cathode material has attracted widespread attention due to its advantages of higher energy density,lower cost,and compatibility with sulfide electrolytes.However,NCM cathode materials have some imperfections,such as low safety and poor cycle stability,and there are still many problems to be solved at its contact interface with sulfide electrolyte.Therefore,the research on the structure and interface optimization of NCM cathode material is of great significance to improve the energy density and stability of lithium-ion batteries.This paper focuses on the research of the current mainstream NCM cathode materials and the matching research of interface problems with sulfide-based solid electrolytes,expounding the challenges,solutions and development opportunities of NCM cathode materials.Prospects are proposed for the further development and application of NCM cathodes.关键词
