“…One of the possible explanations for the expansion of the ESW with the introduction of inorganic filler could be attributed to the generation of insulating oxidized species that passivates the electrode surface at high voltages [37b] . Another explanation is the intimate binding interaction of the ceramic fillers with the polymer‐salt chain, altering the polymer physical properties and hindering the decomposition of electrolytes and thereby expanding the ESW [95b] …”

Solid state zinc ion batteries (ZIBs) and aluminum ion batteries (AIBs) are deemed as promising candidates for supplying power in wearable devices due to merits of low‐cost, high safety, and tunable flexibility. However, their wide‐scale practical application is limited by various challenges, down to the material level. This review begins with elaboration of the root causes and their detrimental effect for four main limitations: electrode‐electrolyte interface contact, electrolyte ionic conductivity, mechanical strength and electrolyte voltage stability window. Thereafter, various strategies to mitigate each of the described limitation are discussed along with future research direction perspectives. Finally, to estimate the viability of these technologies for wearable applications, economic‐performance metrics are compared against Li‐ion batteries.

“…The rise of conductivity values resulted from an increase in the number of charge carriers and mobility by rising ZnO concentration. An extra loading of ZnO NPs caused extra accumulation of ZnO NPs at the surface of the film which might decrease its conductivity as the charge carrier mobility decreased [63]. For 10 wt%, it was found that the conductivity reached a maximum value of 1.2 × 10 −7 Sm −1 .…”

Polymethyl methacrylate (PMMA)/Palm oil/ZnO nanocomposite films of concentrations 0, 0.5, 1, 2, 5, 10, and 15 wt% were prepared by solution casting technique. Tween 80 was used as a surfactant. The prepared films were characterised by different techniques in addition to antimicrobial and cytotoxicity tests. The scanning electron microscope (SEM) micrographs of fractured surfaces of the films showed that palm oil (PO) and Tween 80 enhanced ZnO NPs dispersion. An excess ZnO loading led to polymer saturation with ZnO NPs which accumulate on PMMA surface. X-ray diffraction (XRD) measurements confirmed SEM results as the crystallinity increased by ZnO NPs loading and decreased by excess loading. In addition, the presence of PO and Tween 80 enhanced thermal stability of pure PMMA and the optimum concentration is 0.5 wt% ZnO NPs. Further, the permittivity (ε′), dielectric loss (ε′′), and electrical conductivity (σ) were investigated. It was found that PO addition increased the values of ε′, ε′′, and σ of PMMA. Upon ZnO loading, these values increased up to 10 wt% ZnO NPs then decreased upon reaching 15 wt% ZnO NPs. The conductivity values revealed that the prepared nanocomposites can perform as antistatic materials for lower ZnO content and electrostatic dissipation application at 10 wt% ZnO. The antimicrobial and cytotoxicity studies revealed that the prepared films are nontoxic and the antimicrobial properties of the films against Staphylococcus aureus, Enterococcus faecalis and Candida albicans were enhanced by PO and ZnO NPs addition.

The increased interest in the transition from liquid to solid polymer electrolytes (SPEs) has driven enormous research in the area polymer electrolyte technology. Solid biopolymer electrolytes (SBEs) are a special class of SPEs that are obtained from natural polymers. Recently, SBEs have been generating much attention because they are simple, inexpensive, and environmentally friendly. In this work, SBEs based on glycerol-plasticized methylcellulose/pectin/potassium phosphate (MC/PC/K3PO4) are investigated for their potential application in an electrochemical double-layer capacitor (EDLC). The structural, electrical, thermal, dielectric, and energy moduli of the SBEs were analyzed via X-ray diffractometry (XRD), Fourier transforms infrared spectroscopy (FTIR), electrochemical impedance spectroscopy (EIS), transference number measurement (TNM), and linear sweep voltammetry (LSV). The plasticizing effect of glycerol in the MC/PC/K3PO4/glycerol system was confirmed by the change in the intensity of the samples’ FTIR absorption bands. The broadening of the XRD peaks demonstrates that the amorphous component of SBEs increases with increasing glycerol concentration, while EIS plots demonstrate an increase in ionic conductivity with increasing plasticizer content owing to the formation of charge-transfer complexes and the expansion of amorphous domains in polymer electrolytes (PEs). The sample containing 50% glycerol has a maximal ionic conductivity of about 7.5 × 10−4 scm−1, a broad potential window of 3.99 V, and a cation transference number of 0.959 at room temperature. Using the cyclic voltammetry (CV) test, the EDLC constructed from the sample with the highest conductivity revealed a capacitive characteristic. At 5 mVs−1, a leaf-shaped profile with a specific capacitance of 57.14 Fg−1 was measured based on the CV data.
