Microwave heating followed by a solvothermal method to synthesize nickel–cobalt selenide/rGO for high-performance supercapacitors

Efficient microwave heating followed by a solvothermal method is used to synthesize (Ni 0.85 Se) 3 (Co 0.85 Se)/rGO nanorods with an ultrahigh specific capacitance of 2009 F g −1 at a current density of 2 A g −1 .
