Preparation and characterization of electrospun poly(acrylonitrile) fibrous membrane based gel polymer electrolytes for lithium-ion batteries

Fabrication and properties of polybutadiene rubber-interpenetrating cross-linking poly(propylene carbonate) network as gel polymer electrolytes for lithium-ion battery

“…41 It means that high ion conductivity of GPE is also caused by the high degree of LiPF 6 dissociation by the ether-oxygen atom and the segregated XBRPC framework, which forms more ionic transport channels aer swelling, by absorbing organic electrolyte. 42,43 Meanwhile, the solvent molecules reduce the Li + complexation degree with the oxygen atom, increasing the segmental mobility of the polymer. 9 In general, the combined action of high electrolyte retention, great degree of LiPF 6 dissociation and stable polymeric framework can result in a high ionic conductivity of GPE.…”

Electrospun Nanofibers for Sandwiched Polyimide/Poly (vinylidene fluoride)/Polyimide Separators with the Thermal Shutdown Function

“…Various electrospun membranes from different polymer materials have been attempted as separators to successfully achieve low thermal shrinkage and improved electrolyte uptake, including thermoplastic polyurethane (TPU) [12], polyacrylonitrile (PAN) [13], Poly(vinylidene fluoride) (PVDF) [14], poly(vinylidene fluoride co-hexafluoropropylene) (PVDF-HFP) [15], polyethylene terephthalate (PET) [16] and polyimide (PI) [17]. Trilayer separators basing on electrospun nanofiber membranes have been also explored to further improve the thermal shrinkage and electrochemical performance [18][19][20].…”

Compliant gel polymer electrolyte based on poly(methyl acrylate-co-acrylonitrile)/poly(vinyl alcohol) for flexible lithium-ion batteries

“…Therefore, the application of GPEs in large-scale systems is currently limited [10]. As an effective way of overcoming this intrinsic limitation of the GPE, surface coating on a mechanical framework such as polyolefins or nonwoven fabrics has been proposed [11][12][13]. However, they have several drawbacks, such as complex multi-step processes, relative low ionic conduction and relatively expensive modification of the surface of hydrophobic polyolefins or non-woven fabrics with adequate hydrophilic monomers to increase the surface energy enough to absorb the liquid electrolyte.…”
