A pyrolyzed polyacrylonitrile/sulfur nanocomposite (SPAN) was used as a positive electrode material for a room temperature K-S battery operated in carbonate electrolyte. SPAN presented a high reversible capacity of 270 mA h g(-1) (710 mA h g(sulfur)(-1)) and excellent rate performance, which demonstrate that it is a promising positive electrode material for K-ion and K-batteries.
