CATHODE ACTIVE MATERIAL FOR SECONDARY BATTERY, CATHODE FOR SECONDARY BATTERY INCLUDING THE SAME, SECONDARY BATTERY INCLUDING THE CATHODE FOR SECONDARY BATTERY, AND MANUFACTURING METHODS THEREOF

The present disclosure relates to a cathode active material for a secondary battery, a cathode for a secondary battery including the same, a secondary battery including the cathode for a secondary battery and manufacturing methods thereof. More particularly, it is possible to obtain a secondary battery having excellent electrochemical characteristics by electrochemically inducing a structural phase change in the cathode active material of a secondary battery including NaCl as a cathode active material.
