Supercapacitors: A Three‐Layer All‐In‐One Flexible Graphene Film Used as an Integrated Supercapacitor (Adv. Mater. Interfaces 11/2017)

In article number 1700004, Wei Lv, Quan-Hong Yang, and co-workers demonstrate an all-in-one graphene-based flexible supercapacitor prepared by a step-by-step filtration followed by a selective photo-reduction assisted with TiO2, where unreduced graphene oxide (GO) layers in the middle, act as the separator and the outside reduced GO-TiO2 layers are used as active materials. This supercapacitor shows an extremely high volumetric energy density, excellent rate and cyclic performances together with a very good flexibility.
