Taking another look at the high capacity and shuttle effect of electroactive sulfur at high content, and considering the demands of hybrid capacitors for cathode materials, we propose a use of highly conductive porous carbon loaded a small amount of sulfur as a cathode to well match LIB-type anode. In this situation, the small amount of sulfur filled in the pores of the carbon materials can provide high specific capacity and restrict the dissolution of polysulfides, and the problem of huge capacity difference between cathode and anode of hybrid capacitors will be overcome. Additionally, the kinetics of sulfur based on the redox reaction is similar to that of most anode materials, which narrows the kinetics gap between two electrodes and makes the cathode kinetically match well with the anode.Herein, we reported the use of carbon-sulfur composite as the cathode to improve the energy density of hybrid capacitors. The re- sultant composite cathode delivered a high specific capacity of 212.2 mAh g−1 (424.4 F g−1) at 4 A g−1, much better than that of the activated carbons without sulfur. Benefiting from the high capacity and moderate kinetics of the carbon-sulfur composite cathode, the fabri- cated hybrid capacitors delivered a high energy density of 258.4 Wh kg−1 at 995 W kg−1 and high cycle stability over 3000 running. This result clearly indicates that the carbon-sulfur composite is a promising candidate for high energy density hybrid capacitors, which will give further impetus to explore the fundamental science and applications of sulfur in the context of electrochemical energy storage.
