NOVELTY - A self-supporting high-load sulfur positive electrode comprises a self-supporting matrix, lithium polysulfide and other lithium-containing compounds. The self-supporting matrix is compositely prepared by using a porous carbon skeleton, an active catalyst and a functional polymer. USE - Self-supporting high-load sulfur positive electrode. ADVANTAGE - The self-supporting high-load sulfur positive electrode has high sulfur loading capacity, excellent confinement ability, rapid conversion kinetics, stable structure, and simple composition. The method is easy to realize, process is controllable, has excellent practicability and operability. DETAILED DESCRIPTION - A self-supporting high-load sulfur positive electrode comprises a self-supporting matrix, lithium polysulfide and other lithium-containing compounds. The self-supporting matrix is compositely prepared by using a porous carbon skeleton, an active catalyst and a functional polymer. The lithium polysulfide is of formula: Li2Sx, where x is 4-8. An INDEPENDENT CLAIM is included for preparation of self-supporting high-load sulfur positive electrode.
