摘要: Abstract Lithium-sulfur (Li-S) battery offers a superior alternative to currently commercial lithium-ion batteries because of high energy density, low cost and satisfying safety. However, during the operation, shuttle effect seriously destroys cycle life leads serious capacity degeneration. In recent years, copolymerization strategy, in which elemental sulfur is melted linear polysulfane then copolymerized with polymerizable linker monomer form stable organosulfur polymers, believed as an innovative effective method improve stability Li-S batteries. Due strong covalent bonds between copolymer framework, polysulfides dissolution could be effectively suppressed upon cycling. This paper reviews some efforts on copolymers cathode materials battery. Based these considerations, remaining challenges perspective system are also discussed.
