“…Nyquist plots contain the general characteristics at a high-frequency semiarc region followed by low-frequency spikes. The semiarc corresponds to the bulk characteristics of the system, and the low frequency peak corresponds to the charge build up at the electrode–electrolyte interface. − The obtained experimental data of impedance plots were fitted with an equivalent circuit model using Zsimp Win software. The experimental data perfectly fit with the theoretical model.…”

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.

“…To measure protonic conduction within a specific range, the amplitude signal was substituted with a scan rate input, commonly set at values such as 50 mV s −1 , 10 mV s −1 , and 5 mV s −1 [128,[131][132][133]. It is worth noting that this characterization step is typically conducted before evaluating the long-term cyclability of PCPE when considering its suitability as a component in a full-cell battery setup.…”

“…Additionally, the magnitude of currents in Cell 2 is greater than that in Cell 1, further supporting the presence of proton conduction in the system. Some researchers have found that incorporating a plasticizer into PCPE can enhance protonic conduction in the system [128,133,134]. To confirm protonic conduction in a plasticized system (PEO-NH 4 PF 6 -polysorbate 80), CV techniques have been employed [132].…”

The ever-increasing global population necessitates a secure and ample energy supply, the majority of which is derived from fossil fuels. However, due to the immense energy demand, the exponential depletion of these non-renewable energy sources is both unavoidable and inevitable in the approaching century. Therefore, exploring the use of polymer electrolytes as alternatives in proton-conducting batteries opens an intriguing research field, as demonstrated by the growing number of publications on the subject. Significant progress has been made in the production of new and more complex polymer-electrolyte materials. Specific characterizations are necessary to optimize these novel materials. This paper provides a detailed overview of these characterizations, as well as recent advancements in characterization methods for proton-conducting polymer electrolytes in solid-state batteries. Each characterization is evaluated based on its objectives, experimental design, a summary of significant results, and a few noteworthy case studies. Finally, we discuss future characterizations and advances.
