Title:

METAL-DOPED CATHODE ACTIVE MATERIAL FOR SODIUM SECONDARY BATTERY, PREPARATION METHOD THEREFOR, AND SODIUM SECONDARY BATTERY COMPRISING SAME

Document Type and Number:

WIPO Patent Application WO/2019/017736

Kind Code:

A3

Abstract:

In sodium transition metal oxide particles serving as a cathode active material, a different metal is doped uniformly, which results in an improvement in the physical and electrochemical properties of the material itself as well as stabilizing the structure during charge/discharge cycles, with the consequent enhancement of battery performance.
