Abstract: With the increasing support of the national policy on the electric vehicle, the bottleneck of the electrochemical performance of the Li-ion battery is becoming more and more prominent. The safety of the lithium-ion battery has not been resolved since the material's chemical performance is limited. The effects of lithium, lithium, lithium iron phosphate and ternary materials on the electrochemical performance of lithium-ion battery positive electrode material, lithium, lithium manganate, lithium iron phosphate and ternary material on the electrochemical properties of the battery were summarized.

Key words: lithium-ion battery, cathode material, mix, surface covering
