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

Abstract

A “pseudocomposite” with unique nano-architecture of two Ni(OH)₂/RGO layer was <italic>in situ</italic> 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).
