Fabrication of Green Template Based Flexible Electrodes for Hybrid Supercapacitors

Abstract

For rapid charging transfer and ion transport, multichannel-porous carbon generated from wood can act as a conductive substrate, supporting the high-theory capacitance of pseudocapacitive materials. High-performance supercapacitor electrode materials for NiCo2S4 nanosheets that are hierarchically porous and anchored on the surface of carbonized wood were proposed. The NiCo2S4 nanosheet accumulation was successfully reduced, and the hybrid wood-derived porous carbon-NiCo2S4 nanosheet material (NCS-CW) electrode displayed an 821 F g-1 specific capacity. We believe NCS-CW will be used as an electrode material that holds a lot of potential for energy storage devices because of its excellent electrochemical performance.
