“…The Fe-O and Ni-O stretching modes are present at 574 cm −1 and 422 cm −1 , indicating the creation of NiFe 2 O 4 NPs [18,35]. For (85/15 wt/wt%) PVDF/PEO, according to previous literature [18,36,37], band at 1400 cm −1 corresponds to wagging modes of CH 2 , 1231 cm −1 attributed to CH 2 twisting mode of PEO. The band at 1170 cm −1 is due to the stretching mode of CF 2 of PVDF.…”

Pure nickel ferrite nanoparticles (NiFe2O4 NPs) were prepared by the solvothermal method. Different concentrations of NiFe2O4 were added to PVDF/PEO blend to prepare the PVDF/PEO-NiFe2O4 nanocomposite films. The films were characterized using different techniques in detail. Pure NiFe2O4 NPs images have a semispherical shape and roundness of the edges, with average particle size ~ 4.3–8.8 nm, and polycrystalline structure. Pure NiFe2O4 NPs show that micrometrical agglomeration suggests the presence of pore-free crystallites on the surface. The spectroscopic techniques such as XRD, FTIR, and UV–visible have confirmed the interaction between PVDF/PEO and NiFe2O4 NPs. Still, the nanocomposites exhibit a smooth surface with typical spherulitic clusters revealing the semi-crystalline structure of the PVDF/PEO-NiFe2O4 nanocomposites. The values of ε′ and ε″ were increased as an increase of NiFe2O4 due to the high value of dielectric permittivity of NiFe2O4. The appearance of semi-circles in the plot of M″ with Log confirms the single phase of the samples. The dielectric measurements show that M′ is inversely proportional to ε′. At higher temperatures, M′ levels off at frequencies higher than those at lower temperatures because the relaxation processes were spread over a range of frequencies. The values of saturation magnetization of PVDF/PEO-NiFe2O4 films were linearly increased as an increase of NiFe2O4 indicates improvement in the magnetic vector arrangement. Due to the enhancement of the magnetic properties, they can further exploit the films for magnetic applications.

“…This was due to the formation of free volume provided by alginate from their chain and created unoccupied spaces for migration of ions [37]. The enhancement of ionic conductivity is also attributed to overall mobility of ion and polymer which determined by the free volume; hence, it will leads to the increased in ionic and segmental mobility that will assist ion transport and practically compensate the retarding effect of ion clouds [38]. The segmental motion of the polymer chain and dissociation of the dopant increased due to vibrational energy occurred in the space around its own volume of which believed to push against the hydrostatic pressure imposed by its neighboring atoms [39].…”

In this present work, the conduction properties of biopolymer electrolytes (BEs) based alginate incorporation with LiNO 3 was studied. FTIR analysis showed there is complexation occurred when incorporation with LiNO 3 via COO − group of alginate. The interaction between alginate and LiNO 3 shown an improvement in ionic conductivity of BEs where was increased from 3.24×10 -7 S cm −1 for un-doped sample and achieved optimum value at 1.14×10 -4 S cm −1 for sample containing with 15 wt. % LiNO 3 . The prepared samples shown that it has thermally assisted when the temperature is increased and shown Arrhenius behavior. Deconvolution approached revealed that the present ionic conduction of BEs influenced by ionic mobility and diffusion coefficient.

However, whether active or inert fillers are added to the polymer in the form of randomly distributed nanoparticles, the agglomeration of fillers will be caused by the excessive addition of fillers, which leads to long migration paths and high transport resistance of lithium ion in electrolyte.…”

Summary Polymer solid electrolyte with high ionic conductivity at room‐temperature is most likely to be widely used in solid‐state lithium batteries. In this work, the novel surface lithiated TiO2 nanorods were firstly used as ionic conductor in polymer solid electrolyte. The surface lithiated TiO2 nanorods‐filled polypropylene carbonate polymer composite solid electrolyte (CSE) has an uniform composite structure with a thickness of about 60 μm. The ionic conductivity at room‐temperature is 1.21 × 10−4 S cm−1 and the electrochemical stability window is up to 4.6 V (vs Li+/Li). The assembled NCM622/CSE/Li solid‐state battery shows a stable cycle performance with a retention capacity of 120 mAh g−1 after 200 cycles at the current density of 0.3 C and a high coulomb efficiency of 99%. Compared with TiO2 particles, this novel surface lithiated TiO2 nanorods can provide more continuous ion transport channels and more Lewis acid‐base reactive sites, provide a novel way to enhance the lithium ion transport in polymer solid electrolyte.
