“…On addition of MWCNTs into the polymer matrix, the T D values decrease which confirm, the intermolecular interaction between the polymer and fillers. 73,74 The TGA curves for blend polymers based pn PVA-PEG + NaNO 3 + x wt % of MWCNTs-based composite electrolytes (x = 2.5, 5, 7.5, and 10 wt %) are shown in Figure 5ii(a− blend polymer shows thermal stability 310 °C as reported in Sadiq et al 51 The influence of filler on the polymer blend-salt matrix decreases the thermal stability, which is due to the leading to polymeric backbone because of the disorder the bonding and thermal resistance of the polymers reported in Hirankumar et al 75 The thermal stability of the polymer blend composite electrolytes raises up to above 230 °C for the 7.5 wt % MWCNTs fillers. Consequently, standard polymer electrolyte is thermally more stable as compared with liquid electrolyte and favored when used in portable all solid-state electrochemical energy storage devices.…”

“…The FTIR technique has been used to understand structural, microstructural and chemical structure variations in the intensity of the distinctive bands in the polymer composites. , The salt (NaNO 3 ) and polymer (PVA-PEG) interaction with filler MWCNTs has been investigated by using an FTIR spectrophotometer. The analysis of FTIR spectra of pure PVA, pure PEG, and blended PVA-PEG are discussed in the previous work of Sadiq et al The spectra and data of polymer blend PVA-PEG + NaNO 3 + x wt % of MWCNTs and attached functional groups are shown in Figure ii(a–d) and Table , respectively. In the FTIR spectra of the MWCNT-doped polymer blend the salt complex exhibits the peaks related to pure PVA, pure PEG, NaNO 3 , and MWCNTs fillers and confirmed the formation of the composite. − The spectrum also confirmed the interaction between the polymer’s functional group and the fillers.…”

New polymer blend composite electrolytes (PBCEs) were prepared by the solution casting technique using poly(vinyl alcohol) (PVA)-polyethylene glycol (PEG), sodium nitrate (NaNO3) as a doping salt and multiwalled carbon nanotubes (MWCNTs) as fillers. The X-ray diffraction pattern confirms the structural properties of the polymer blend composite films. FTIR investigations were carried out to understand the chemical properties and their band assignments. The ionic conductivity of the 10 wt % MWCNTs incorporated PVA-PEG polymer blend was measured as 4.32 × 10–6 S cm–1 at 20 °C and increased to 2.253 × 10–4 S/cm at 100 °C. The dependence of its conductivity on temperature suggests Arrhenius behavior. The equivalent circuit models that represent the R s(Q1(R1(Q2(R2(CR3))))) were used to interpret EIS data. The dielectric behavior of the samples was investigated by utilizing their AC conductance spectra, dielectric permittivity, dielectric constant (εi and εr), electric modulus (Mi and Mr), and loss tangent tan δ. The dielectric permittivity of the samples increases due to electrode polarization effects in low frequency region. The loss tangent’s maxima shift with increasing temperature; hence, the peak height rises in the high frequency region. MWCNTs-based polymer blend composite electrolytes show an enhanced electrochemical stability window (4.0 V), better transference number (0.968), and improved ionic conductivity for use in energy storage device applications.

Herein, we present the synthesis of a nanocomposite blend of polyvinyl alcohol (PVA), polyethylene glycol (PEG), sodium nitrate (NaNO3), and various weight percent of nanofillers, BaTiO3, using a simple standard solution casting technique. The prepared nanocomposites are characterized in detail via techniques such as X‐ray diffraction technique, field‐emission scanning microscope, FTIR, and Raman spectra for confirming the crystal structure, morphology, and chemical bond formation within the samples, respectively. The suitable ionic conductivity of prepared samples is in the range of 10−4–10−8 S/cm at room temperature. Further, its maximum electrochemical stability window is ~4.1 V, and the ionic transference number is about 0.96 (15 wt%) at room temperature. The results associated with the optimized polymer nanocomposite motivated us to check its practical applicability for supercapacitors. The cyclic voltammetry of the fabricated cell based on optimized polymer as separator cum electrolyte appears as a distorted rectangle with no redox peaks. The cell charge storage mechanism is explored to be the electric double layer (EDLC) in nature. The maximum specific capacitance exhibited by the cell is nearly 4.4 F/g at a scan rate of 3 mV/s. The energy and power densities delivered by the same cell are equal to 27.7 W h kg−1 and 9972 W kg−1, respectively, which sustain for 100 cycles. The results of the designed cell reveal that both blend polymer composite electrolyte films and the composite electrode can be implemented to be used for EDLC supercapacitor.

“…Rechargeable solid-state sodium ion (Na + ) polymer batteries are excellent candidates for advanced charge storage devices. SPEs based on Na salts have been extensively developed and studied for battery applications [ 3,4 ] because they are alternative to the lithium (Li) saltsbased SPEs used since a long time. It is well known that the Li compounds are hazardous.…”

We studied the effect of titanium dioxide (TiO2)nanoparticles (NPs)on ion conductivity of Na+ ion-conducting nanocomposite solid polymer electrolyte (NCSPE) composed of polymers poly(ethylene oxide) (PEO) and polyvinyl pyrrolidone (PVP), sodium metaperiodate (NaIO4)at concentration 10 wt%, and with added TiO2NPs of average size ∼ 10 nm at concentration from 1 wt% to 5 wt%. The electrical response of thin films (150μm) of PEO/PVP/NaIO4/TiO2 was characterized by employing the complex electrical impedance spectroscopy. The changes in ion-conducting properties of the examined NCSPEs induced from the included TiO2 NPs, were explained.
