lithium manganate powder benefits

    lithium manganite  is a promising one of lithium ion battery anode materials, compared with the traditional anode materials, such as cobalt acid lithium manganese acid lithium is rich in resources, low cost, no pollution, good safety, ratio performance is good wait for an advantage, is the ideal power battery cathode material, but its poor circulation and electrochemical stability performance is greatly limits its industrialization.Lithium manganate mainly includes spinel lithium manganate and layered structure lithium manganate, among which spinel lithium manganate structure is stable, easy to realize industrial production, now the market products are this kind of structure.Spinel type lithium manganate belongs to cubic crystal system, Fd3m space group, theoretical specific capacity is 148mAh/g, due to the three-dimensional tunnel structure, lithium ions can be reversely removed from the spinel lattice inset, will not cause the collapse of the structure, thus has excellent multiplicity performance and stability.

    Now, the traditional thought of lithium manganate energy density low, poor cycling performance shortcomings have been greatly improved (Wanli New energy typical value: 123mAh/g, 400 times, high circulation type typical value 107mAh/g, 2000 times).Surface modification and doping can effectively modify its electrochemical properties, and surface modification can effectively inhibit manganese dissolution and electrolyte decomposition.The JAHn-Teller effect in charge and discharge process can be effectively inhibited by doping.The combination of surface modification and doping can undoubtedly improve the electrochemical performance of the material, and it is believed that it will be one of the research directions for the modification of spinel lithium manganate in the future.
