“…This result proves that no chemical interactions occur after the addition of ZnO, and hence its only physical interactions between PVA and ZnO are involved. Mansour et al 37 was reported the same findings where there are no chemical interaction between PVA and ZnO. Further, Figure 4b shows the FTIR spectra of PVA/4 wt% ZnO at different KOH concentrations.…”

Aluminum-air battery is a promising future energy storage device because it has a high energy density and is eco-friendly. The effects of zinc oxide filler on polyvinyl alcohol/alkaline solid polymer electrolyte for aluminum-air battery applications have been investigated. From the impedance measurement, the highest ionic conductivity achieved was 1.61 × 10 −2 S cm −1 by PVA/4 wt% ZnO/2 M KOH at room temperature. From XRD analysis, crystallinity intensity decreased when KOH was added into the system. The FTIR also showed that the O-H and C-O bonds shifted to a high wavenumber, from 3282 to 3383 cm −1 and 1092 to 1103 cm −1 , respectively, as the KOH concentration increased, which strengthened the bonding in the film. Thus, LSV analysis showed that the highest stability achieved by PVA/4 wt% ZnO/2 M KOH was ±2.15 V, which proved that this film is suitable in aluminum-air battery applications. Furthermore, in the aluminum-air coin cell, the longest discharge voltage time was achieved by PVA/4 wt% ZnO/2 M KOH in which the cell voltage was maintained at 1.49 to 1.53 V for almost 20 hours at 0.8 mA/cm 2 .
