Synthesis of Ni(OH) 2 /RGO pseudocomposite on nickel foam for supercapacitors with superior performance

A “pseudocomposite” with unique nano-architecture of two Ni(OH) 2 /RGO layer was in situ synthesized on nickel foam (NF) using a facile onepot hydrothermal approach, which exhibits superior capacitive performance (15.65 F cm −2 at 7 mA cm −2 , 90.6% capacity retention after 5000 cycles at 20 mA cm −2 ).
