Abstract
The present invention relates to a sulfur-containing positive electrode material for a secondary battery, a preparation method thereof, and a secondary battery. The sulfur-containing positive electrode material is obtained by uniformly mixing microporous polyacrylonitrile (with a pore diameter of 0.2-2 nm) as a precursor with elemental sulfur and then performing heating treatment. The microporous polyacrylonitrile is obtained through free radical polymerization of an acrylonitrile monomer and a crosslinking agent.
