Three-dimensional porous graphene frameworks functionalized with redox molecules can be used for the fabrication of highly flexible solid-state supercapacitors as demonstrated by Xiangfeng Duan and co-workers on page 5779. These devices reveal superior capacitive performances and extraordinary mechanical flexibility. The cover design is by Nathan Weiss.
