Mechanically flexible reduced graphene oxide/carbon composite films for high-performance quasi-solid-state lithium-ion capacitors

The free-standing rGO/carbon composite films were designed via a facial strategy as high-performance LIC electrodes without any addition of conductive agents or binders while enabling the fabricated flexible quasi-solid-state rGO/AC//rGO/HC LIC to possess high energy/power density and ultra-long cycle stability.
