HIGH-CONDUCTIVITY SULFUR-BASED POSITIVE ELECTRODE MATERIAL FOR SECONDARY BATTERY AND SECONDARY BATTERY

A high-conductivity sulfur-based positive electrode material for a secondary battery and a secondary battery are provided. The sulfur-based positive electrode material is formed by evenly mixing highly isotactic polyacrylonitrile as a precursor with elemental sulfur and then heating to undergo a chemical reaction. The highly isotactic polyacrylonitrile is synthesized from an acrylonitrile monomer by means of a free radical polymerization or inclusion polymerization reaction under the action of a template agent.
