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.

PMMA Based Gel Polymer Electrolytes
2000Gel 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 ...

Gellan Gum-LiI Gel Polymer Electrolytes
Molecular Crystals and Liquid Crystals, 2012Gellan-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

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 ...

Cellulose triacetate‐based polymer gel electrolytes
Journal of Applied Polymer Science, 2009AbstractNew 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,

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 electrolyte for lithium-ion batteries
Electrochimica Acta, 2008Abstract The electrochemical performance of gel electrolytes based on crosslinked poly[ethyleneoxide-co-2-(2-methoxyethyoxy)ethyl glycidyl ether-co-allyl glycidyl ether] was investigated using graphite/Li1.1[Ni1/3Mn1/3Co1/3]0.9O2 lithium-ion cells. It was found that the conductivity of the crosslinked gel electrolytes was as high as 5.9 mS/cm at room
