It is crucial to develop flexible and wearable electronic devices that have attracted
tremendous interest due to their merits on compactness, flexibility and high capacitive
properties. Herein we report the continuously ordered macroscopic poly (ionic liquid)-
graphene fibers by wet spinning method via liquid crystal assembly for supercapacitor
application. The fabricated all-solid-state supercapacitors exhibited a high areal capacitance
(268.2 mF cm− 2) and volumetric capacitance (204.6 F cm− 3) with an outstanding areal …
