Abstract

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 Li(2)SO(4) electrolyte due to the polypyrrole coating.

摘要

为了探索硫在水系可充电电池中的潜在应用，通过一种新颖的一锅法和无表面活性剂法制备了核壳结构的硫-聚吡咯（S@PPy）复合材料。由于聚吡咯的包覆，硫在水系 Li(2)SO(4)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。
