Cheng-Wei Huang, Ching-An Wu, Sheng-Shu Hou, Ping-Lin Kuo, Chien-Te Hsieh and Hsisheng Teng Gel Electrolyte Derived from Poly(ethylene glycol) Blending Poly(acrylonitrile) Applicable to Roll-to-Roll Assembly of Electric Double Layer Capacitors Advanced Functional Materials 22
A gel electrolyte derived from swelling a copolymer of poly(ethylene glycol) blending poly(acrylonitrile) with LiClO4/dimethyl formamide exhibits high ionic conductivity and excellent compatibility with carbon-based supercapacitors. The copolymer substantially reduces resistance to ionic motion across the partition zone and through the carbon/electrolyte interface. The adjustable mechanical integrity of this gel-electrolyte film makes roll-to-roll assembly of supercapacitors scalable to industrial levels.
