Flammability of Gel Polymer Electrolytes

ECS Meeting Abstracts
Gel 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, 2001
New 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, 2007
Multifunctional 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, 1999
Abstract 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, 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%.

Swelling of ionic gels in electrolyte solutions

Industrial & Engineering Chemistry Research, 1990
Etude du gonflement de gel copolymeres acrylamide/acrylate de sodium et acrylamide/N-[(trimethylammonio-3) propyl] methacrylamide dans les solutions aqueuses de pH et force ioniques variables. Le degre de gonflement des gels depend fortement de la concentration des ions antagonistes mobiles.

Electrochemistry of polyvinyl acetate gel electrolytes

Solid State Ionics, 2002
Abstract This paper describes the first example of polyvinyl acetate (PVAc) used as a gel electrolyte with a short-chain polyethylene glycol (MPEG-400) as a plasticizer. The polymer films are solid and sticky. Background cyclic voltammetry (CV) shows a potential window between +0.4 and −0.7 V vs. AgQRE.

A gel polymer electrolyte of magnesium triflate

Solid State Ionics, 2000
Investigations leading to understanding and development of solid state rechargeable magnesium batteries are important in view of the fact that the Mg is free from hazards, it's stability is high and it's natural resources are abundant. A $Mg^{2+}$ ion conducting gel polymer electrolyte (GPE) is investigated for a possible application in solid state ...

Gel electrolytes with plasticizers of different polarity

Solid State Ionics, 1996
Abstract Gel electrolytes were prepared by photopolymerization of oligo(ethylene glycol)23 dimethacrylate ((EG)23DMA) in the presence of LiCF3SO3 and various oligo(ethylene glycol) derivatives as plasticizers. The influence of the chain length and the end groups, i.e.
