Transport of Neutral and Ionic Solutes: The Gel/Electrode and Gel/Electrolyte Interfaces [PDF]
Langmuir, 2009 Transport through a polysaccharide gel phase has been investigated voltammetrically using both redox voltammetry at a gel covered electrode and ion transfer voltammetry across the gel/liquid interface (Gel/L). The apparent diffusion coefficients, D(app), of a range of neutral and ionic electroactive species have been determined in both uncharged and ...

Journal of Visualized Experiments, 2022
Supercapacitors (SC) have attracted attention as energy storage devices due to their high density and long cycle performance. SCs used in devices operating in stretchable systems require stretchable electrolytes. Gel polymer electrolytes (GPEs) are an ideal replacement for liquid electrolytes.

Gel Polymer Electrolytes Design for Na‐Ion Batteries
Small Methods, 2022AbstractNa‐ion battery has the potential to be one of the best types of next‐generation energy storage devices by virtue of their cost and sustainability advantages. With the demand for high safety, the replacement of traditional organic electrolytes with polymer electrolytes can avoid electrolyte leakage and thermal instability.

Ion transport in gel electrolytes
Electrochimica Acta, 1995Abstract 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 ...

Thermoreversible polymer gel electrolytes
Polymer, 1994Abstract Thermoreversible polymer gel electrolytes with ionic conductivities in the region of 10−3 S cm−1 (even at −20°C) have been prepared from a variety of commercially available polymers and organic solvents by gel casting from high-temperature solutions at polymer/solvent ratios down to 10 90 .

Proton Batteries with Hydroponics Gel as Gel Polymer Electrolyte
Electrochemical and Solid-State Letters, 2007A proton conductor gel polymer electrolyte based on hydroponics gels (HPG) mixed with 10 M ammonium nitrate (NH 4 NO 3 ) was found to yield a very high electrical conductivity of 0.60 S cm -1 . The optimized composition, i.e., the HPG-10 M NH 4 NO 3 , was then used in our proton battery to make a Zn + ZnSO 4 ·7H 2 O/HPG-10 M NH 4 NO 3 /MnO 2 system ...

Synthesis and characterization of highly conducting gel electrolytes
Electrochimica Acta, 1994Abstract The electrochemical properties of gel electrolytes formed by the immobilization in a poly(acrylonitrile) matrix of solutions of common lithium salts (eg LiClO4, LiAsF6 and LiN(CF3SO2)2) in organic solvents (eg the propylene carbonate—ethylene carbonate mixture, γ-butyrolactone or the γ-butyrolactone-ethylene carbonate mixture) have been ...

An electrolyte is a major component that influences battery performance. The electrolytes for lithium-ion batteries can be mainly divided into liquid electrolyte, gel polymer electrolyte and solid electrolyte. The liquid electrolyte used in commercialized lithium-ion batteries is based on lithium salt dissolved in organic solvents.

Proton-conducting gel electrolyte
Solid State Ionics, 2002Abstract Proton conduction in solid state xerogels and polymeric gels are reported. Xerogels, doped with known proton conductors, were prepared by “sol–gel” method starting either from inorganic precursor sodium metasilicate (termed as hydrogel) or organic precursor tetraethyl orthosilicate (termed as silica or SiO 2 alcogel). The dopants chosen for
