▎ 摘 要
NOVELTY - Self-supporting lithium-sulfur battery positive electrode material comprises three-dimensional reinforced graphene-sulfur compound. USE - The self-supporting lithium-sulfur battery positive electrode material is used as positive electrode for lithium-sulfur batteries without adding conductive carbon black and polyvinylidene fluoride (PVDF) (claimed). ADVANTAGE - The lithium-sulfur battery has simple operation, low cost, environmental protection, high utilization rate of active material and excellent cycle stability and alleviates problems of poor conductivity, shuttle effect and volume expansion.
