摘要
Abstract
As one of the cathode materials for lithium ion batteries,lithium manganese phosphate has the advantages of high energy density,good safety and low cost,and is considered as the ideal upgrade of lithium iron phosphate.However,the low conductivity and Li+ diffusion coefficient of lithium manganese phosphate limit its commercial appli-cation.The properties of lithium manganese phosphate material were introduced,and the advantages and disadvanta-ges of synthesis method such as high temperature solid state method,coprecipitation method,sol-gel method and hy-drothermal/solvothermal method were summarized.the modification strategies such as carbon coating,nanocrystalli-zation,morphology control and ion doping were summarized.It was pointed out that lithium manganese phosphate materials should have a suitable atomic ratio of manganese and iron.On the basis of summarizing previous research achievements,the future research directions of lithium manganese phosphate cathode materials were prospected.关键词
