Lithium manganate battery.solar battery generator

　　Lithium manganate is one of the more promising lithium ion positive materials. Compared with traditional orthopedic materials such as cobaltate, lithium manganate has the advantages of rich resources, low cost, pollution -free, good safety, and good performance. Power battery positive materials, but its poor circulation performance and electrochemical stability have greatly limited its industrialization. Lithium manganate mainly includes lithium spine -lithium manganate and lithium -shaped structures. Among them, the structure of spinel -galginite lithium manganate is stable and easy to achieve industrialized production. Today, the market products are all in this structure. Speed stone -shaped lithium manganate belongs to the cubic crystal system, FD3M space group, and the theoretical ratio is 148mAh/g. Due to the three -dimensional tunnel structure, lithium ions can be removed from the spinel stone lattice, which will not cause the structure. The collapse has excellent perception performance and stability.

　　Today, the disadvantages of traditional lithium manganate energy density and poor circulation performance have been greatly changed (Wanli New Energy Typical Value: 123mAh/G, 400 times, high -circulating typical value of 107mAh/g, 2000 times). The surface modification and the effective modification of the doped electrochemical properties, surface modification can effectively suppress the dissolution and electrolyte decomposition of manganese. Duplicate can effectively suppress the Jahn-Teller effect in the process of charging and discharge. It is believed that the combination of surface modification and doping can undoubtedly improve the electrochemical properties of materials, and it is believed that it will become one of the directions for the study of tsubite lithium mangible in the future.
