| 英文摘要 | for the first time, we have shown a novel supercapacitor system with a graphene paper electrode in the redox-electrolyte of k3fe(cn)(6) based on the system-level design principle. 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 graphene 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 (similar to 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. |
