α-NiO/Ni(OH)₂/AgNP/F-Graphene Composite for Energy Storage Application.

ABSTRACT: The α-NiO/Ni(OH)₂/AgNP/F-graphene composite, which is silver nanoparticles preanchored on the surface of fluorinated graphene (AgNP/FG) and then added to α-NiO/Ni(OH)₂, is investigated as a potential battery material. The addition of AgNP/FG endows the electrochemical redox reaction of α-NiO/Ni(OH)₂ with a synergistic effect, resulting in enhanced Faradaic efficiency with the redox reactions of silver accompanied by the OER and the ORR. It resulted in enhanced specific capacitance (F g^-1) and capacity (mA h g^-1). The specific capacitance of α-NiO/Ni(OH)₂ increased from 148 to 356 F g^-1 with the addition of AgNP(20)/FG, while it increased to 226 F g^-1 with the addition of AgNPs alone without F-graphene.
