Nanobiomimetic supercapacitors with high rate high energy storage

Abstract

Nanobiomimetic supercapacitors comprise an 'Electron Well' and an 'Electron-Dam' Membrane Electrode Assembling (MEA); the “Electron-Well” MEA compromises an electrode comprising a substrate of glassy carbon; a self-assembling membrane comprises a polymer matrix; wherein the polymer matrix is comprised of an electrically conductive copolymer; wherein the copolymer is further comprised of one or more first β-cyclodextrin molecules having at least one or more free acetyl groups; one or more polyethylene glycol molecules; one or more poly(4-vinylpyridine) molecules; and one or more second β-cyclodextrin molecules; the self-assembling membrane having a surface structure comprising one or more nanopores and pillars; the nanopores and pillars are vertically oriented on the substrate to form nanopore and pillar array; the “Electron-Dam” MEA compromises the nanopore/pillar layer sealed with an embedded hydrophobic aromatic substance having a flat lid structure; Wherein the MEA can be as either said positive or negative electrode; wherein the “Electron-Well” also can be either said as positive or negative electrode; separated by a porous insulator wetted by an electrolyte-free and air-independent organic solution; at least two current collectors are at each of the end of the MEAs.
