Abstract
A nanofoam nickel cobalt layered double hydroxide (NiCo(OH)2) electrode film is fabricated on a stainless-steel substrate with the use of a simple one-step solvothermal process. The nanofoam NiCo(OH)2 electrode exhibits a high specific capacitance of 2710.2 F/g at a current density of 9.1 A/g, and a good capacity retention of ∼70% after 2000 charge-discharge cycles at a high current density of 31.8 A/g. An energy density of 60.23 Wh/kg is obtained at a power density of 1.8 kW/kg. The excellent electrochemical energy storage performance of the NiCo(OH)2 electrode is due to the synergetic effect of a significantly improved ionic diffusion and an effective charge transfer, which is linked to a well-dispersed interconnected nanofoam morphology and binder-free direct contact with the current collector.
