Abstract

We have explored a new method to produce flexible and all-solid-state graphene fiber supercapacitors (GFSs) from wet-spun graphene fibers. The GFSs exhibited high capacitance (3.3 mF cm−2) and good stability (almost no changes occur after 5000 charge cycles and bending cycles). Moreover, we decorated GFSs with polyaniline nanoparticles and the resulting pseudocapacitors exhibited a capacitance of 66.6 mF cm−2.
