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.

Ionic Gel Electrolytes for Electrochromic Devices
ACS Applied Materials & InterfacesIonic gels are emerging as a promising solution for improving the functionality of electrochromic devices. They are increasingly drawing attention in the fields of electrochemistry and functional materials due to their potential to address issues associated with traditional liquid electrolytes, such as volatility, toxicity, and leakage.

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

Flammability of Gel Polymer Electrolytes
ECS Meeting AbstractsGel polymer electrolytes are promising technology for next-generation lithium batteries, offering a balance between the high ionic conductivity of liquids and the safety of polymers. Although it is often suggested that gel polymer electrolytes are safer than traditional organic electrolytes, there is a lack of systematic research available on the ...

Gel polymer electrolytes based on PMMA
Electrochimica Acta, 2001New polymer gels (based on PMMA/PC) containing Li, Na, Mg, and Zn perchlorates were prepared. The conductivity of gels containing cations of smaller ionic radii (Li and Mg) is lower than that of the others.

Multifunctional Properties of Structural Gel Electrolytes
ECS Transactions, 2007Multifunctional structural gel electrolytes were prepared by the integration of conductive pathways using non-aqueous solvents into structural resin networks. Poly(ethylene) glycol (200 MW) and propylene carbonate were used as non-aqueous solvents while vinyl ester and epoxy resin were used as structural resins.

Polymer gel electrolytes for electrochromic devices
Electrochimica Acta, 1999Abstract Elastic and sticky polymer gel electrolytes were prepared by polymerisation of methacrylate resin to which solutions, containing LiBF 4 and [(C 2 H 5 ) 4 N]BF 4 in various ratios in PC, were added, keeping the ionic strength constant. A concentration cell containing two polymer samples and two equal LiHg x electrodes was used for the ...

Plasticized pectin-based gel electrolytes
Electrochimica Acta, 2009Abstract 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%.
