Structure, modification, and commercialization of high nickel ternary material (LiNi0.8Co0.1Mn0.1O2and LiNi0.8Co0.15Al0.05O2) for lithium ion batteries

LiNi0.8Co0.1Mn0.1O2(NCM811), as one of the most promising cathode materials for lithium ion batteries, has gained a huge market with its obvious advantages of high energy density and low cost. It has become a competitive material among various cathode materials. However, in NCM811, the phenomenon of cationic mixed discharge is serious, resulting the cyclic performance performing badly. In addition, the thermal stability of ternary material will also be poor with the increase of nickel when temperature is high. In view of the above-mentioned situation, researchers come up with different methods to modify LiNi(0.8)Co(0.1)Mn(0.1)O(2)by doping and coating to reduce mixing effect and improve its electrochemical performance. Here, we sketch out the structure, properties, and existing problems of NCM811 and summarize some cutting-edge modification methods. Finally, the development direction and commercial application of NCM811 cathode materials are prospected to accelerate its commercialization process.

Automated summary

NCM811, a promising cathode material for lithium ion batteries, has gained a huge market with its high energy density and low cost. However, issues such as serious cationic mixed discharge phenomenon and poor thermal stability need to be addressed by modifying methods to enhance its electrochemical performance.
