Abstract: It introduces the research progress in blending modification cathode materials for lithium ion batteries. The cathode material is the most important part of lithium battery. It is becoming the bottleneck to the increase of energy density and the decrease of cost of lithium ion batteries. The blending modification cathode materials has been proven to be a promising approach to improve the electrochemical performance in battery production process. Blending modification cathode materials has the advantages of low-cost and simple preparation process. It has been expected to be a promising approach to design advanced electrodes based on material characteristics for future lithium-ion batteries. The article also points out that the research of properties matching, charging and discharging mechanisms and blend process were urgently needed.

Key words: lithium ion batteries, cathode material, blending modification
