SURFACE TREATMENT METHOD FOR POSITIVE ELECTRODE LAYER PHASE STRUCTURE OXIDE FOR LITHIUM SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a surface treatment method for a layer phase structure oxide for improving thermal stability of a lithium secondary battery. SOLUTION: In this surface treatment method for the positive electrode layer phase structure oxide for the lithium secondary battery, the surface of the layer phase structure oxide is treated by coated with lithium transfer metal oxide. The lithium secondary battery manufactured by using the oxide as the active material has the superior thermal stability.
