2021-08-03Physical and chemical properties of lithium manganate
Lithium manganate is one of the more promising lithium ion cathode materials. Compared with traditional cathode materials such as lithium cobalt oxide, lithium manganate has the advantages of rich resources, low cost, no pollution, good safety, and good rate performance. It is ideal The power battery cathode material, but its poor cycle performance and electrochemical stability greatly limit its industrialization. Lithium manganate mainly includes spinel type lithium manganate and layered structure lithium manganate. Among them, spinel type lithium manganate has a stable structure and is easy to realize industrial production. Nowadays, the products on the market have this structure. Spinel lithium manganate belongs to the cubic crystal system, Fd3m is empty 345345, the theoretical specific capacity is 148mAh/g, due to the three-dimensional tunnel structure, lithium ions can be reversibly extracted from the spinel lattice without causing The structure collapses, so it has excellent rate performance and stability.
