Intercalation-type pseudocapacitive clustered nanoparticles of nickel–cobalt phosphate thin films synthesized via electrodeposition as cathode for high-performance hybrid supercapacitor devices

Alteration of Ni : Co composition in nickel–cobalt phosphate electrodes leads morphological evolution from microspheres to nanosheets and exhibits transformation from the battery-intercalation-intrinsic pseudocapacitive-type charge storage mechanism.
