Hierarchical Core/Shell Structured Ag@Ni(OH)2 Nanospheres as Binder-Free Electrodes for High Performance Supercapacitors

Hierarchical Ag@Ni(OH)2 nanospheres were achieved directly on copper foam substrate through a convenient two-step process.Ag nanoflowers were formed on copper substrate EZEKIEL BREAD WHOLE GRAIN by galvanic replacement technology between AgNO3 and copper foam followed by electrodeposition of a layer of Ni(OH)2.Ag nanostructures as cores not only do
