Unique all-graphene core–sheath fibers composed of a graphene fiber core with a sheath of 3D graphene network have been developed. Used as flexible electrodes, all-solid-state fiber supercapacitors have been fabricated, which can be managed to highly compressible and stretchable spring supercapacitors and can also be woven into a textile for wearable electronics.
