摘要
CONSPECTUS:Lithium−sulfur(Li−S)batteries have been extensively studied because both S and Li have high theoretical capacities,and S is abundant and environmentally friendly.However,their practical applications have been hindered by several challenges,including poor conductivity of S and its intermediates,shuttle effects of polysulfides,Li dendrite growth,etc.Tremendous efforts have been taken to tackle these issues by developing functional S host materials,separators and interlayers,solid-state electrolytes,etc.,during the past decade.Compared to structurally complicated materials and intricate preparation approaches,electrospun nanofibers have obtained tremendous interests since they have played an extremely crucial role in improving the overall performance of Li−S cells due to their unique features such as easy-setup,substantial surface area,outstanding flexibility,high porosity,excellent mechanical properties,etc.
