METHOD FOR PREPARING HIGH PERFORMANCE CATHODE ACTIVE MATERIALS FOR LITHIUM SECONDARY BATTERIES AND LITHIUM SECONDARY BATTERIES COMPRISING THE SAME

摘要

The present invention provides a mixed solution by dissolving an insoluble lithium compound and an insoluble metal compound in an acid solution as a raw material; Removing the solvent of the mixed solution to form a homogeneous dry matter; It provides a method for producing a lithium metal oxide for a lithium secondary battery positive electrode active material comprising the heat treatment at a temperature in the range of 500 ~ 1500 ^o C and a lithium metal oxide prepared according to the lithium secondary battery, .
