Review on Defects and Modification Methods of LiFePO 4 Cathode Material for Lithium-Ion Batteries

In recent years, domestic and international researchers have been committed to the research of lithium-ion batteries. As the key to further improving the performance of the battery, the quality of the cathode material directly affects the performance indicators of the lithium battery; thus, the cathode material occupies the core position in the lithium-ion battery. LiFePO4 is a relatively excellent material for lithium-ion batteries, which has many advantages of low cost, high capacity, and environmental friendliness. However, as a result of the low conductivity of lithium iron phosphate and the slow diffusion rate of lithium ion, the development of lithium iron phosphate in the power battery industry is…
