PRECURSOR COMPRISING MULTI LAYERED TRANSITION METAL OXIDES FOR PRODUCING CATHODE ACTIVE MATERIAL AND CATHODE ACTIVE MATERIAL PRODUCED USING PRECURSOR FOR LITHIUM SECONDARY BATTERY

摘要

Provided are a precursor for producing cathode active material and cathode active material produced using the precursor for a lithium secondary battery the precursor which is for producing cathode active material for a secondary battery comprising: a core containing transition metal hydroxides comprising nickel (Ni) and manganese (Mn) or transition metal hydroxides comprising nickel (Ni) manganese (Mn) and cobalt (Co); and a shell containing transition metal hydroxides comprising cobalt (Co).
