  • LITHIUM MANGANESE OXIDE SPINEL AND MANUFACTURING METHOD THEREFOR
    Publication number: 20180114982
    Abstract: Lithium manganese oxide material used in lithium ion battery is disclosed herein. The lithium manganese oxide material may be doped with suitable dopant. The lithium manganese oxide material may be represented by a first formula of Li1+xMyMn2?y?xO4, wherein the value of ‘x’, in the first formula, satisfies a relation ?0.1<x<0.3 and the value of ‘y’, in the first formula, satisfies a relation a relation 0?y?0.2. The lithium manganese oxide material may further be coated with a shell capping layer. The shell capping layer may be made of a carbon or a compound having a second formula, Li1+xMyMn2?y?xO4. In an aspect, the value of ‘x’, in the second formula, may satisfy a relation ?0.1<x<0.3. Further, the value of ‘y’, in the second formula, may satisfy a relation 0?y?0.2.
