One-step electrodeposition synthesis of high performance Graphene/Cu2O nanocomposite films on copper foils as binder-free supercapacitor electrodes

Providing a good contact between electroactive materials and their substrates is an important factor for developing supercapacitors. In our work, a Graphene (Gr)/cuprous oxide (Cu2O) nanocomposite film was directly fabricated on a Cu foil by a simple one-step electrodeposition approach. The obtained binder-free electrode (referred as Gr-Cu2O nanocomposite/Cu foil) was directly used as a working electrode for supercapacitors. The electrochemical...
