“…The composite polymer electrolyte (CPE) based on PEO is a promising candidate owing to the low glass transition temperature (À60 C), high Li + solvation ability and admirable interfacial stability with lithium. [5][6][7][8][9] However, the low room temperature conductivity (10 À7 to 10 À6 S cm À1 ), narrow electrochemical windows and inferior mechanical properties of PEO are the main obstacles for further development. 4,7,9 Blending is one of the valid approaches to ameliorate the properties of PEO, such as with PVP, 10 PVDF, 11 and PMMA; 12 this can decrease crystallization and enhance the fractional movement of polymer chains and the migration amount of Li + .…”

“…Apart from the scientific interest, the utilization of Na has many benefits over their lithium counterparts; Na is available in abundance at a less expensive value than atomic number lithium. A few attempts were created to develop electrolytes based on sodium/polymer complexes films [32][33][34]. So, in the present investigation, an attempt has been created to characterize the nanostructure and the electrical conduction of polymer electrolytes based on PVA complexes with NaI at totally different weight percentages to evaluate their potential in electrochemical cells.…”

Positron annihilation lifetime (PAL), AC conductivity, and impedance spectroscopy have been applied for the investigation of polyvinyl alcohol (PVA) doped with different concentrations of NaI in the range from zero to 25 wt%. Wide‐angle x‐ray diffraction measurements reveal that the addition of NaI to the PVA structure leads to a decrease in the crystallinity of the sample. The free volume size obtained from PAL measurements increases with the increase of the NaI concentration on PVA. NaI acts as an inhibitor of positronium formation on the doped polymer with inhibition constant of 0.028 (Mol%)−1. The ionic conductivity of the investigated sample was found to be correlated with the free volume size, which indicates the major role of free volume in the conduction mechanism. The AC conductivity of the prepared samples is measured at room temperature in the frequency range from 50 Hz to 5 MHz. The calculated values of frequency exponent s indicate the hopping mechanism in ionic conductivity. Impedance spectroscopy of PVA doped with different concentrations of NaI was studied. The appeared semi‐circle, in the Nyquist plot, denotes the bulk influence of PVA with different concentrations of NaI. This has been attributed to the parallel connection of bulk resistance and bulk capacitance. Also, the semi‐circle radius of Cole‐Cole plots was found to decrease with the increase of the concentration ratio (wt%) of NaI. So, the increase of the conductivity of PVA with the increase of NaI contents has been investigated.

Flexible energy storage devices have gained significant attention because of the increasing needs of bendable displays, wearable electronics, and flexible displays. Flexible Na‐based rechargeable batteries are the promising power sources in such products due to their low cost and wide availability. In this review, we firstly introduce the structural superiority of flexible Na‐based batteries and summarize their main components including cathodes, electrolytes, and anodes. Moreover, fabrication of their flexible components is discussed in detail, with specific emphasis on material selection, particularly for solid‐state electrolytes. This is followed by an overview highlighting recent progress in the development of prototypes of flexible Na‐ion batteries and beyond. Finally, perspectives on future challenges for the development of flexible Na batteries are proposed.
