Stepwise assembled nickel-cobalt-hydroxide hetero-accumulated nanocrystalline walls on reduced graphene oxideickel foams: an adjustable interface design for capacitive charge storage

摘要

To achieve a balance of a high specific capacitance between the electroactive materials and electrodes with adjustable specific energy and power, evaporation-induced nickel-cobalt-hydroxide hetero-accumulated nanocrystalline walls on reduced graphene oxideickel foams are presented by different Ni-doping and dipping numbers. The flexible solution-based strategy promotes a new interface design for capacitive charge storage.
