Abstract

Abstract:

LiFePO₄ has the characteristics of high temperature stability,good cycle performance and environmental protection etc..It has become one of the cathode materials for lithium ion power batteries.However,due to the low electronic conductivity of LiFePO₄ and the slow diffusion rate of lithium ions,the application of LiFePO₄ in power battery industry is restricted. Therefore,it was summarized the improvement of LiFePO₄ from three aspects：surface modification of LiFePO₄ with carbon coated materials,doping LiFePO₄,preparing submicron or nanometer LiFePO₄ or the LiFePO₄ with special morphology.The optimum method of improving LiFePO₄ was analyzed and its development trend in the future was predicted.

Key words: Lithium ion battery, lithium iron phosphate, cathode material
