Title:

METHOD FOR MANUFACTURING CATHODE MATERIAL FOR SECONDARY BATTERY ELECTRODE

Document Type and Number:

WIPO Patent Application WO/2020/059927

Kind Code:

A1

Abstract:

The present invention provides a method for manufacturing a cathode material for a secondary battery and, more specifically, provides a method for manufacturing a cathode material for a secondary battery, the method comprising a step of binding graphene oxide onto the surface of a Prussian white structure and then reducing the graphene oxide. A secondary battery manufactured by comprising an electrode using the cathode material can have excellent initial capacity and lifetime characteristics.
