Abstract:

Lithium-ion conducting nanocomposite solid electrolytes were synthesized from polyethylene oxide (PEO), poly(methyl methacrylate) (PMMA), LiClO4, and Li1.3Al0.3Ti1.7(PO4)3 (LATP) ceramic particles. The synthesized nanocomposite electrolyte consisted of LATP particles and an amorphous polymer. LATP particles were homogeneously distributed in the polymer matrix. The nanocomposite electrolytes were flexible and self-standing. The lithium-ion conductivity of the nanocomposite electrolyte was almost an order of magnitude higher than that of the PEO/PMMA solid polymer electrolyte.

This paper describes the preparation and characterization of proton conducting nanocomposite polymer electrolytes based a polyvinylidene fluoride-co-hexapropylene (PVDF-HFP) for protonic electrochemical cells. The electrolytes were characterized by Differential Scanning Calorimetry (DSC) and Impedance Spectroscopy (IS). It is observed that the crystallinity of the PVDF-HFP-NH4CF3SO3 system slightly increase upon addition of SiO2 nanofiller.

The effect of ZnO nanoparticles on the structure and ionic relaxation of LiI salt doped poly(ethylene oxide) (PEO) polymer electrolytes has been investigated.

The electrical conductivity of the nanocomposites is found to increase due to incorporation of ZnO nanoparticles. We have shown

Abstract:

Composite polymer electrolytes provide an emerging solution for new battery development by replacing liquid electrolytes, which are commonly complexes of polyethylene oxide (PEO) with ceramic fillers. However, the agglomeration of fillers and weak interaction restrict their conductivities. By contrast with the prevailing methods of blending preformed ceramic fillers within the polymer matrix, here we proposed an in situ synthesis method of SiO2 nanoparticles in the PEO matrix. In this case, robust chemical interactions between SiO2 nanoparticles, lithium salt and PEO chains were induced by the

Abstract:

Elementary processes of electro mass transfer in the nanocomposite polymer electrolyte system by pulse field gradient, spin echo NMR spectroscopy and the high-resolution NMR method together with electrochemical impedance spectroscopy are examined. The new nanocomposite polymer gel electrolytes consisted of polyethylene glycol diacrylate (PEGDA), salt LiBF4 and 1—ethyl—3—methylimidazolium tetrafluoroborate (EMIBF4) and SiO2 nanoparticles. Kinetics of the PEGDA matrix formation was studied by isothermal calorimetry. The flexible polymer–ionic liquid films were studied by IRFT spectroscopy, diffe

Abstract:

The problems of development portable low-temperature hydrogen-air solid polymer electrolyte fuel cells (SPEFC), medium-temperature methane-air fuel cells (SOFC) and supercapacitors (SC) with pseudocapacity effect are described in the article. These devices are promising to use in a variety of vehicles, including the sector of the magnetic levitation transport, as an alternative to low-speed movement. The current trends in the development of nanocomposite electrode materials, electrolytes SPEFC, SOFC and the SC are analyzed briefly. Examples of the use of materials synthesized by various method

Abstract:

A kind of nanocomposite polymer based on poly(acrylonitrile-methyl methacrylate) [P(AN-MMA)] copolymer was prepared by in situ polymerization of monomers on the surface of TiO2 nanoparticles, which come from the hydrolysis of Ti(OC4H9)4. Analysis of Fourier transform-infrared (FT-IR) spectra indicated that the acrylonitrile (AN) monomers copolymerized with the methyl methacrylate (MMA) monomers by breaking their own double bonds. The dependence of ionic conductivity on temperature for the resulting nanocomposite polymer electrolyte (NCPE) followed the Arrhenius equation. The ionic conductivity

Abstract:

Nanocomposite solid polymer electrolytes comprise of PMMA (poly methyl methacrylate), PVP (poly vinyl pyrolidone), MSA (methanesulfonic acid) and TiO2 as nanofiller were prepared by solution casting technique at different compositions. Sample with 1 mol% incorporated TiO2 has shown maximum conductivity and its value was found as 2.82 ×10-5 S/cm. The value of conductivity has been enhanced to about 31% upon the addition of nanofiller. The relaxation time for all the prepared composites as well as for the composite having maximum conductivity at various isotherms have been calculated from the lo

Abstract:

Nanocomposite polymer electrolytes (NPEs) were synthesized using sodium alginate (Alg) and either sodium (SCa-3-Na+)- or lithium (SCa-3-Li+)-modified montmorillonite clays. The samples were characterized by structural, optical, and electrical properties. SCa-3-Na+ and SCa-3-Li+ clays’ X-ray structural analyses revealed peaks at 2θ = 7.2° and 6.7° that corresponded to the interlamellar distances of 12.3 and 12.8 Å, respectively. Alg-based NPEs X-ray diffractograms showed exfoliated structures for samples with low clay percentages. The increase of clay content promoted the formation of intercala

Abstract:

Lithium metal batteries (LMBs) are a key product for sustainable and efficient electric transport. Long-life and safe LMBs require the development of solid or semisolid (e.g., gel polymer) electrolytes capable of blocking lithium dendrites. In this context, Janus double-faced membranes (JMs) offer interesting perspectives, as they allow for modulating the properties of each side according to specific requests. In this paper, we report on facile fabrication via the solvent casting of JMs based on poly(vinylidene fluoride hexafluoropropylene) (PVDF-HFP). Here, an electronically insulating layer
