Cationic transport in gel electrolytes on basis of oligo(ethylene glycol) dimethacrylate

Modern generation of polymer electrolytes based on lithium conductive imidazole salts

“…in the systems with very high passive/charge transfer resistance (more than order of magnitude higher than electrolyte one) [26,27]. Bruce and Vincent method was also used in the oligo(ethylene) systems [28]. It was also a practical advantage to use this method.…”

Polymer gel electrolytes synthesized by photopolymerization in the presence of star-shaped oligo(ethylene glycol) ethers (OEGE)

“…Therefore, both cross-linking monomers and plasticizers including segments of oligo(ethylene glycol) (EG n ) have been studied as components for gel electrolyte films [4][5][6][7][8][9][10].…”

Star-shaped oligo(ethylene glycol) ethers (OEGE) as a new type of plasticizer for polymer gel electrolytes

“…Studies on such gels showed that an increase of the polarity by insertion of a polar comonomer or by use of polar plasticizers leads to a decrease of the ionic association, but not in significantly higher ionic conductivities [15,17,18]. This was explained by a diminished mobility due to the partial incorporation of plasticizer molecules in the polymer matrix [13,19] and dipol -dipol interactions of the polar plasticizers with itself and the polymer [17,18].…”

“…This was explained by a diminished mobility due to the partial incorporation of plasticizer molecules in the polymer matrix [13,19] and dipol -dipol interactions of the polar plasticizers with itself and the polymer [17,18]. The ionic conductivity seems to be more dependent on the oligomerization degree n of the EG n based monomer and plasticizer, i.e.…”

“…The ionic conductivity seems to be more dependent on the oligomerization degree n of the EG n based monomer and plasticizer, i.e. it depends on the ability of the plasticizer to coordinate the Li + cations in competition to the polymer [17,18]. That means, it can be increased by use of EG n DMA with low n for the polymer and use of EG n DME with high n as a plasticizer.…”
