This work reports on the development of ionic liquid (IL)/poly(vinylidene fluoride) (PVDF) actuator composites. ILs sharing same anion (bis(trifluoromethylsulfonyl)imide, [TFSI]−), and different cations belonging to families pyridinium, imidazolium, ammonium ions, comprising an alkyl side chains with variable length, were used. The physical–chemical properties, thermal behavior, mechanical, electrical, bending responses PVDF/IL composites evaluated. incorporation into PVDF matrix leads...
The application of microporous structures as active fillers for solid polymer electrolytes (SPEs) affects battery performance and this review presents the state art materials (MOFs zeolites) SPE in solid-state batteries.
Environmental issues related to energy consumption are mainly associated with the strong dependence on fossil fuels. To solve these issues, renewable sources systems have been developed as well advanced storage systems. Batteries main system mobility, and they applied in devices such laptops, cell phones, electric vehicles. Lithium-ion batteries (LIBs) most used battery based their high specific capacity, long cycle life, no memory effects. This rapidly evolving field urges for a systematic...
The use of metal–organic frameworks in the separator membrane lithium-ion batteries is an interesting subject study for next generation energy storage devices. In this work, different poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) / framework (MOF) based separators were prepared using three distinct MOFs, and properties these membranes studied. selected MOFs MOF-808, UiO-66-NH2 MIL-125 are characterized by sharing a common building block (cluster or linker) possessing relatively...
The growing demand for energy storage devices calls the development of more efficient and sustainable systems. As current lithium-ion batteries present several safety issues, as well environmental hazards, some alternatives need to be taken into consideration. area organic materials based is gaining interest they allow replacing currently used metals, with significant impact at levels extractions processing, by redox-active materials, that are recyclable environmentally friendly. In this...
In the realm of polymer composites, there is growing interest in use mora than one filler for achieving multifunctional properties. this work, a composite separator membrane has been developed lithium-ion battery application, by incorporating conductive silver nanowires (AgNWs) and titanium dioxide (TiO2) nanoparticles into poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) matrix. The membranes were manufactured solvent casting thermally induced phase separation, with total content...
The search for sustainable and high-performance materials lithium-ion batteries is leading to significant advances in solid polymer electrolyte (SPE) technology.

Solid polymer electrolytes (SPEs) are the necessary step towards solid-state lithium-ion batteries (LIBs). Their function as separator and electrolyte allows to increase safety of energy storage devices by elimination liquid components. In this work, three-component SPEs based on poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) host polymer, clinoptilolite zeolite, different ionic liquids (ILs) (1-ethyl-3-methylimidazolium thiocyanate ([EMIM][SCN]), 1-butyl-3-methylimidazolium...
Solid-state batteries were produced using new solid polymer electrolytes (SPEs) based on the high dielectric constant poly(vinylidene fluoride-trifluoroethylene-chlorofluoroethylene), P(VDF-TrFE-CFE) and 40 wt% of different ionic liquids (IL) sharing same bis(trifluoromethylsulfonyl)imide [TFSI] anion cations. The morphological, thermal, mechanical electrochemical properties SPEs investigated, as a function interaction between IL matrix. addition increased amorphous phase with respect to...
Renewable energy sources require efficient storage systems. Lithium-ion batteries stand out among those systems, but safety and cycling stability problems still need to be improved. This can achieved by the implementation of solid polymer electrolytes (SPE) instead typically used separator/electrolyte system. Thus, ternary SPEs have been developed based on poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) fluoride-trifluoroethylene-chlorofluoroethylene), P(VDF-TrFE-CFE) as host...
Solid polymer electrolytes (SPEs) have been produced using an ionic liquid (IL) (1-Methyl-1-propylpyrrolidinium bis(trifluoromethylsulfonyl)imide – [PMPyrr][TFSI]) embedded in different fluorinated matrices, including poly(vinylidene-fluoride) PVDF, poly(vinylidene fluoride-co-hexafluoropropylene) P(VDF-HFP), fluoride-co-trifluoroethylene) P(VDF-TrFE) and fluoride-co-trifluoroethylene-chlorofluoroethylene) P(VDF-TrFE-CFE), order to evaluate the effect of chain polarity, degree crystallinity...
