Amorphous MoSx thin-film-coated carbon fiber paper as a 3D electrode for long cycle life symmetric supercapacitors†
Abstract
Amorphous MoSx thin-film-coated carbon fiber paper as a binder-free 3D electrode was synthesized by a facile hydrothermal method. The maximum specific capacitance of a single electrode was 83.9 mF cm−2, while it was 41.9 mF cm−2 for the symmetric device. Up to 600% capacitance retention was observed for 4750 cycles.
