英文摘要Cobalt-based composites are generally investigated as cathode for supercapacitor due to its excellent electrochemical properties. Here, we explore its application as anode with the potential window of -0.3 -0 V in 6 M KOH aqueous electrolyte. Interconnected Co3O4/CoO/Co(OH)(2) nanosheets array is one-step electrodeposited on the surface of active carbon cloth, but showing low capacitance. Surprisingly, after in-situ compositing with MnO2 (ratio of Mn4+ is similar to 23%), the hybrid MnO2/cobalt composites nanosheets array anode delivers similar to 705 F g(-1) at 0.68 A g(-1), much higher than that of similar to 161 F g(-1) for pristine Co3O4/CoO/Co(OH)(2). Besides, using NiCO2S4 nanosheet array@ nickel foam as cathode, the asymmetric supercapacitor exhibits high specific capacitance of 198 F g(-1) at the current density of 0.5 A g(-1). This work manifests a promising strategy to explore novel anode material and improve their properties, which holds great promise in energy storage/conversion devices.
