METAL-DOPED CATHODE ACTIVE MATERIAL FOR SODIUM SECONDARY BATTERY, METHOD FOR MANUFACTURING THE SAME, AND SODIUM SECONDARY BATTERY COMPRISING THE SAME

Other Metals are uniformly doped in a sodium transition metal oxide particle to obtain a cathode active material. As a result, it is possible to improve the battery performance by improving the physical properties of the material itself and stabilizing the structure during the charge/discharge process as well as electrochemical properties.
