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

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

“…6) although the dissociation degree of the salt increases with increasing CyMA content of the polymer. However, this behaviour corresponds with the reduced mobility of the plasticizer molecules at higher CyMA contents as detected by DSC and DMA [21].…”

Polyhedral oligomeric silsesquioxane containing gel polymer electrolyte based on a PMMA matrix

“…[28][29][30][31][32][33][34][35] The obtained results reveal that inorganic nano-particle llers usually improve GPE performances through the following micro-effects: the capillary action produced by nano-particles can tightly capture the plasticizer in GPE and evidently increase ionic conductivity and electrochemical stability of GPE; 36 the Lewis acid and base action existing between nanoparticles and the lithium salt in GPE can promote the extent of lithium salt dissociation and enhance the conductivity; 37 the tremendous surface area of nanoparticles endows GPE with improved mechanical strength and leads to easier membrane formation.

“…The most outstanding advance in this eld has been the incorporation of inorganic nanoparticle llers into GPE.

A gel polymer electrolyte based on a novel synthesized matrix of a self-doped polymer of h-poly(methyl methacrylate-vinyl trismethoxy silane)

“…So in some reports, these monomers such as MMA, AN, EO and VDF were chosen to synthesize copolymer used as matrix for GPE. In addition, designing special structure such as combshape, 27 gra-shape, 28,29 star-shape 30 and crosslink-shape 31 for polymer matrix is also a very interesting measure. Each structure can promise characteristic property in one aspect.…”

“…To quest for improving comprehensive properties of GPE by incorporating inorganic nanoparticles into electrolyte system is another promising method. The inorganic nanoparticles includes metal oxide, such as MgO, 32,33 ZnO, 34 Al 2 O 3 , [32][33][34][35] TiO 2 , [34][35][36][37][38]42 15,[43][44][45][46][47][48] carbon nanotube, 14 clay mineral 29 found in many references. However, the high surface energy from large surface area of all inorganic nanoparticles usually leads to particle agglomeration, which negates any benets associated with the nanoparticles.…”
