Facile and controllable synthesis of sea urchin-like CuCoO on Ni foam for high-performance supercapacitors.

CuCoO is considered to be an attractive electrode material for supercapacitors due to its low toxicity, high theoretical capacity and low cost. However, the low specific capacity, poor cycling performance and low intrinsic conductivity limit the further application of CuCoO. In this research, CuCoO arrays with different morphologies (rods, sea urchin-like and flakes) were synthesized on the surface of nickel foam (NF) a solvothermal method and calcination.
