CATHODE ACTIVE MATERIAL FOR LITHIUM SECONDARY BATTERY, CATHODE FOR LITHIUM SECONDARY BATTERY AND LITHIUM SECONDARY BATTERY

Abstract: a cathode active material for a lithium secondary battery has a structure of a lithium transition metal oxide. a ratio of a crystallite size of a (003) plane to a crystallite size of a (110) plane measured by an x-ray diffraction (xrd) analysis is in a range from 0.7 to 2.0, and a ratio of the crystallite size of the (003) plane to a crystallite size of a (104) plane measured by the xrd analysis is in a range from 0.7 to 2.0. a cathode for a lithium secondary battery and a lithium secondary battery include the cathode active material for a lithium secondary battery.
