POSITIVE ELECTRODE ACTIVE MATERIAL FOR SODIUM SECONDARY BATTERY, AND METHOD FOR PREPARING SAME

摘要

The present invention relates to a positive electrode active material for a sodium secondary battery, and a method for preparing the same. The positive electrode active material for the sodium secondary battery according to the present invention is structurally more stable by replacing a part of the transition metal with Li, and accordingly, the thermal stability and life characteristics of the sodium battery comprising the positive electrode active material are greatly improved.
