Sulfur covalently bonded to porous graphiticcarbon (CB-S@PGC) as anode forlithium-ion capacitors is shown to offer an ultrawide operating potential windowof 4 V. When coupled with activated carbon as cathode, the CB-S@PGC electrode exhibits markedly high specific capacitance (412 F g-1 at0.2 A g-1) and superiorly high capacity retention. And CB-S@PGC//lithium cobalt oxide cellsexhibit high power and energy densities (e.g., a power density of 1665 W kg-1 is obtained at a energy density of 411 Wh kg-1).
