▎ 摘　　要

The alpha-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 alpha-NiO/ Ni(OH)2, is investigated as a potential battery material. The addition of AgNP/FG endows the electrochemical redox reaction of alpha-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 alpha-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. The specific capacitance of alpha-NiO/Ni(OH)2/AgNP(20)/FG further increased up to 1153 F g-1 with a change in the voltage scan rate from 20 to 5 mV/s and the Nafion-free alpha-NiO/Ni(OH)2/AgNP(20)/FG composite. In a similar trend, the specific capacity of alpha-NiO/Ni(OH)2 increased from 266 to 545 mA h g-1 by the addition of AgNP(20)/FG. The performance of hybrid Zn-Ni/Ag/air electrochemical reactions by alpha-NiO/Ni(OH)2/AgNP(200)/FG and Zncoupled electrodes indicates a potential for a secondary battery. It results in a specific capacity of 1200 mA h g-1 and a specific energy of 660 W h kg-1, which is divided into Zn-Ni reactions of -95 W h kg-1 and Zn-Ag/air reactions of -420 W h kg-1, while undergoing a Zn-air reaction of -145 W h kg-1.
