Ultralight and flexible supercapacitor electrodes made from Ni(OH)₂nanosheets doped with Ag nanoparticle/3D graphene composite

Abstract

Ag nanoparticle doped Ni(OH)₂nanosheets are deposited on flexible 3D graphene by a facile hydrothermal method. The electrode shows high specific capacitance with an increase of ~23% and excellent rate capability. The electrode also has good cycle stability.
