Cellulose triacetate‐based polymer gel electrolytes

Journal of Applied Polymer Science, 2009
AbstractNew composite polymer gels were obtained from cellulose triacetate (CTA), N‐methyl‐N′‐propylpyrrolidinium bis(trifluoromethanesulfonyl)imide (Pyr1,3TFSI), and lithium bis(trifluoromethanesulfonyl)imide (LiTFSI). Analysis by differential scanning calorimeter and scanning electron microscope showed that the ionic gel consisting of CTA, Pyr1,3TFSI,

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.

Gellan Gum-LiI Gel Polymer Electrolytes

Molecular Crystals and Liquid Crystals, 2012
Gellan-based polymer electrolytes (PEs), doped with lithium iodide (LiI), were prepared and their electrical properties were characterized. The samples are thermally stable up to 234°C and exhibit ionic conductivity of 3.8 × 10−4 S/cm at room temperature for the sample doped with 40 wt% of LiI. Addition of 10 wt% of glycerol promotes an increase of the

Bacto agar-based gel polymer electrolyte

Ionics, 2011
The biopolymer of a Bacto agar-based gel polymer electrolyte (GPE) was prepared by addition of NaI and I2 as redox couple. The prepared GPE was characterized using impedance spectroscopy and X-ray diffraction (XRD) in order to determine its electrical and structural properties, respectively.

Tailoring the Properties of Gel Polymer Electrolytes for Sodium-Ion Batteries Using Ionic Liquids: A Review.

Chemistry
Ionic liquids are an extraordinary group of compounds, fully ionic in structure like inorganic salts but with low melting points, that resemble organic molecular solvents. Their chemical, electrochemical, and thermal stability is what draws the attention

PMMA Based Gel Polymer Electrolytes

2000
Gel polymer electrolytes based on PMMA and Li salts in PC have been developed for lithium electrochemistry in batteries and electrochromics (for references, see [1]). We have developed a method for their preparation by direct polymerization of PMMA with addition of Li salts in PC, and we have applied this principle to gel electrolytes containing ...

Proton Batteries with Hydroponics Gel as Gel Polymer Electrolyte

Electrochemical and Solid-State Letters, 2007
A 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 ...

Gel Polymer Electrolyte for Aluminum-Ion Batteries

ECS Transactions, 2021
Aluminum-based batteries have potential advantages such as low flammability, low cost, and 3 electrons in the reaction that give them high charge capacity. Current research focuses on aluminum-ion batteries with carbon-derived cathodes that have achieved fast-charge capability and long-term stability; however, present some problems as: the ...
