为了探索硫在水溶液二次电池中的潜在应用，采用一锅法制备了硫-聚吡咯（S@PPy）核壳复合材料。由于聚吡咯涂层，硫在Li 2SO 4水溶液电解质中表现出非常高的容量（473 mA h g（-1））和良好的循环稳定性。
In order to explore the potential application of sulfur in aqueous rechargeable batteries, core-shell sulfur-polypyrrole (S@PPy) composites were prepared through a novel one-pot and surfactant-free method. Sulfur exhibits a very high capacity of 473 mA h g(-1) and good cycling stability in an aqueous Li2SO4 electrolyte due to the polypyrrole coating.
