Asymmetric Super Capacitors Fibers Prepared By Wet Spinning of 2D Nano Materials and Carbon Nanotubes

Fiber-based super capacitors have yielded a considerable amount of attention owing to the ease of fabrication at the industrial scale and the ability to include novel two-dimensional nano materials. Two such materials include molybdenum disulfide (MoS2) and tungsten disulfide (WS2) which have garnered a great deal of attention and have previously been utilized as electrode materials. Herein, fibers were fabricated by a wet spinning process utilizing different dispersions of carbon nanotubes and 2D materials. The resultant fibers are assembled into an asymmetric supercapacitor, where the MoS2 fiber represents the anode material, and the WS2 fiber represents the cathode, with a sulfuric polyvinyl alcohol gel acting as the separating membrane. Finally fiber properties are characterized for overall strength and electrical properties such as conductance and capacitance.
