Abstract:Flexible supercapacitors are challenged by low energy density and short discharge time. We report a new type of biomimetic pyruvate dehydrogenase complex (BIMPDC) supercapacitors having the self-assembling membrane (SAM) offer orders of magnitude higher in power, energy density, and current density compared with the reported flexible supercapacitors, based on nanobiomimetic reversible membrane potential and an asymmetric design with features of flexibility and tenability under the conditions of electrolyte-free and without metal catalyst. Two models are used for assembling the prototype supercapacitors: (1) Supercapacitor #1 with a feature of a flat and vertical nano bridged structures and supercapacitor #2 has a nanopore structure in one side and another side is a flat and poreless structured membrane electrode assembling (MEA). The results shown both supercapacitors are turntable for three different angles from 450, 900 to 1800. They are switchable in connection from both ends having the reversible membrane potential (RPM) characteristics. The current density reaches 1.25 A/cm2, power density is 7.74 kW/g, and the energy density is 13.1 kwhr/kg for the bridged supercapacitor 1 and the specific capacitance is 54,112 F/g which is two orders of magnitudes higher than the reported performance for flexible supercapacitors.
