Immobilization of tungsten disulfide nanosheets on active carbon fibers as electrode materials for high performance quasi-solid-state asymmetric supercapacitors

A novel tungsten disulfide/active carbon fiber (WS₂/ACF) nanocomposite was synthesized through electrospinning and a subsequent hydrothermal method, with the WS₂ nanosheets homogeneously decorated on the surface of the one-dimensional active carbon fiber.
