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.

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 provides a composite wherein NaCl nanoparticles are uniformly dispersed on reduced graphene oxide (rGO), a positive electrode active material including the same, a sodium secondary battery including the same, and a method for preparing the same. The positive electrode active material according to the present disclosure has a structure wherein NaCl nanoparticles are uniformly dispersed on rGO in a one-step process through chemical self-assembly. Therefore, the positive electrode active material according to the present disclosure exhibits superior electrochemical properties with high capacity because the small NaCl particles are dispersed uniformly and is economically favorable because the preparation process is simple.
