Title:
POSITIVE ELECTRODE ACTIVE MATERIAL FOR SODIUM ION BATTERY AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/039639
Kind Code:
A1
Abstract:
The present invention relates to a positive electrode active material for a sodium ion battery and a manufacturing method therefor, wherein a surface sodium byproduct is inhibited by adjusting the content of sodium in a synthetic procedure. The manufacturing method for a positive electrode active material for a sodium ion battery according to the present invention comprises the steps of: preparing a metal oxide powder represented by Na1-xMO2 (M=Mn, Fe, Co, Ti, Ti, Mg, Cr, V, or Ni, and 0
