COMPOSITION FOR CATHODE ACTIVE MATERIAL SURFACE TREATMENT, METHOD FOR PREPARING SAME, AND CATHODE ACTIVE MATERIAL SURFACE-TREATED WITH SAME

摘要

The present invention relates to a composition for cathode active material surface treatment, a method for preparing same, and a cathode active material surface-treated with same and, more specifically, to a composition for cathode active material surface treatment, a method for preparing same, and a cathode active material surface-treated with same, wherein the composition comprises titanium dioxide coated with an ion activator. Therefore, the surface treatment with the composition for surface treatment of the present invention can perform a process of coating titanium on a surface while reducing residual lithium.
