Abstract

A cathode material includes a lithium composite oxide matrix including lithium (Li) and at least one selected from the group consisting of cobalt (Co), nickel (Ni), manganese (Mn), and aluminium (Al), and has a surface layer which is a rocksalt structure and includes tungsten (W); and a material layer formed on the surface layer of the lithium composite oxide matrix and including tungsten (W) and lithium (Li). The cathode material of the present application provides excellent high-temperature cycle and high-temperature storage performance, and the capability of discharge at a high rate, and improves the safety performance of the electrochemical device.
