The rechargeable lithium-sulfur (Li/S) battery system, based on the mental lithium asanode and sulfur as cathode, is increasingly attractive due to its high theoretical specificcapacity and high theoretical specific energy. In addition, sulfur also has the advantage ofabundance, low cost, environment friendly. So Li/S battery system is the most promisecandidate for high specific energy rechargeable lithium battery. However, the insulatingnature of sulfur and discharge products and the loss of polysulfides i...
