Abstract

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.
