Ion transport in gel electrolytes

Electrochimica Acta, 1995
Abstract Gel electrolyte films were prepared by a redox initiated copolymerization of oligo(ethylene glycol) 23 dimethacrylate and acrylonitrile in the presence of oligo(ethylene glycol) 11 dimethyl ether as a plasticizer and LiCF 3 SO 3 . The influence of the polar comonomer acrylonitrile on the conductivity and the cationic transference number ...

Proton conducting polymer gel electrolytes

Solid State Ionics, 1999
Abstract Novel proton conducting gel electrolytes from poly(vinylidene fluoride)-dimethylformamide-H 3 PO 4 system are synthesized and characterized by impedance spectroscopy, infra-red spectroscopy and differential scanning calorimetry. Highly conducting (5×10 −4 S/cm at 20°C) colorless polymeric membranes are obtained in a relatively narrow ...

Plasticized pectin-based gel electrolytes

Electrochimica Acta, 2009
Abstract Pectin is a natural polymer present in plants and, as all natural polymers has biodegradation properties. Chemically, pectin is a polysaccharide composed of a linear chain of 1→4 linked galacturonic acids, which is esterified with methanol at 80%.

PMMA-based aprotic gel electrolytes

Solid State Ionics, 2004
Aprotic electrolytes are essential for lithium batteries, electrochromic windows, electrochemical supercapacitors and similar systems. These materials can be also used in the solid-state electrochemical sensors. This paper deals with the basic properties of gel polymer electrolytes based on propylene carbonate immobilised by polymethylmethacrylate (MMA)
