Supercapacitor is one of the hot spots in the research and development of chemical energy storage devices in recent years，and electrode materials play a decisive role in its performance.In order to synthesize NiCo based two-dimensional layered double hydroxide（LDH） electrode materials with excellent supercapacitor performance，NiCo-LDH nanoarrays were first prepared on the surface of Ni foam by one-step hydrothermal method.Then，in a water-glycol system，VO3- doped NiCo-LDH nanoarrays were prepared through a secondary solvothermal reaction.Finally，electrode materials with excellent performance were obtained through alkali conversion.Using this electrode and activated carbon to assemble an all solid-state asymmetric supercapacitor device，the device showed an energy density of 0.416 mW·h/cm2 at a voltage of 0 to 1.8 V and a power density of 9 mW/cm2，and it had good cycle stability.
Key words： Ni foam; NiCo-LDH; vanadate; nanoarray; supercapacitor
