It was reported by CIAC scientists on their recent published paper that a novel supercapacitor system with a graphene paper electrode in the redox-electrolyte of K3Fe(CN)6 based on the system-level design principle was shown for the first time. By combining electric double-layer capacitance and pseudocapacitance, the specific capacitance could be increased 5-fold compared with the conventional electrode–electrolyte system. This large improvement is attributed to the additional redox reactions on the grapheme paper electrode via the constituent ions of K₃Fe(CN)₆ in the redox-electrolyte, during which the discharge process is highly enhanced. More importantly, the potential interval could reach as high as 1.6 V beyond the limited operating voltage of water (∼1.23 V). After 5000 continuous cycles, 94% of the initial capacitance was retained. The newly designed novel supercapacitor system is binder-free, conducting additive-free and can deliver higher capacitance. This designed graphene-paper-electrode/redox-electrolyte system can provide a versatile strategy for high capacitance supercapacitor systems.
