  • Lithium cobalt metal oxide powder, method for making the same, and method for determining content of cobalt (II,III) oxide
    Patent number: 11784309
    Abstract: A lithium cobalt metal oxide powder is disclosed in the present disclosure. The lithium cobalt metal oxide powder has a coating structure. The lithium cobalt metal oxide powder includes a lithium cobalt metal oxide matrix. The lithium cobalt metal oxide powder further includes a Co3O4 coating layer. A general formula of the lithium cobalt metal oxide powder is LiaCo1-x-yMxNyO2·rCo3O4, wherein 0.002<r?0.05, 1?a?1.1, 0<x?0.02, 0?y?0.005, and a<1+3r; M is a doping element; and N is a coating element. A method for making the lithium cobalt metal oxide powder as described above and a method for determining a content of Co3O4 therein are further provided. The material made in the present disclosure has an excellent electrochemical performance.
