Fig. 16 a Digital photograph of the flexible battery. b Schematic illustration of the flexible
battery configuration. c Galvanostatic charge/discharge curves of the flexible battery
nanomaterials in its composite in graphene paper form and in the conventional
electrode form with CB and PVDF binder, from which we can see both reversible
capacity and cycling stability can be improved by composite into graphene paper.
