▎ 摘  要

NOVELTY - A lithium sulfur battery positive electrode material is formed by alternate stacking of N-layer graphite-metal layers and sulfur layers, where N is natural number. The graphite-metal layer includes nano-graphene and nano-metal oxides. The sulfur layer includes sulfur and nanographene. The thickness of cathode material of lithium-sulfur battery is 1-200 mu m. The thickness of graphite-metal layer or sulfur layer is 0.5-50 mu m. The separated graphite-metal layers interweave to form three-dimensional network structure that is connected. USE - Lithium sulfur battery positive electrode material. ADVANTAGE - The lithium sulfur battery positive electrode material has excellent conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of lithium sulfur battery positive electrode material.
