“…Gelatin properties are influenced by several factors, such as the source, animal age, and collagen type. It has widespread applications, for example, emulsifiers, foaming agents, biodegradable packaging materials, and colloid stabilizers [39]. Gelatin is a polydisperse protein that is composed of a mixture of different chain types with varying molecular weights [40].…”

With the continuing efforts to explore alternatives to petrochemical-based polymers and the escalating demand to minimize environmental impact, bio-based polymers have gained a massive amount of attention over the last few decades. The potential uses of these bio-based polymers are varied, from household goods to high end and advanced applications. To some extent, they can solve the depletion and sustainability issues of conventional polymers. As such, this article reviews the trends and developments of bio-based polymers for the preparation of polymer electrolytes that are intended for use in electrochemical device applications. A range of bio-based polymers are presented by focusing on the source, the general method of preparation, and the properties of the polymer electrolyte system, specifically with reference to the ionic conductivity. Some major applications of bio-based polymer electrolytes are discussed. This review examines the past studies and future prospects of these materials in the polymer electrolyte field.

“…Examples of commonly used plasticizers are glucose, glycerol and sorbitol [22]. According to [23], glycerol is the most suitable plasticizer because of its mechanical characteristics and transparency. Also, the increase in glycerol contents can promote mobile ions to penetrate the polymer matrix.…”

The concern about environmental problems has inspired a of energy storage devices from natural sources. In this study, solid polymer electrolyte (SPE) films made from corn starch doped with different compositions of sodium iodate (NaIO3) were prepared via the solution casting technique. The effect of dopants on the structure, morphology and electrical properties of SPE films was analysed using X-Ray diffraction (XRD), scanning electron microscopy (SEM) and electrochemical impedance spectroscopy (EIS) analysis. From the XRD, it shows that the amorphous state would influence the conductivity values of SPE films. Then, the SEM observations revealed that the films seem to be rough, porous and having branch structure, which may affect the conductivity of SPE films. The maximum conductivity of SPE film is obtained from 3 wt.% of NaIO3 with a value of 1.08 × 10−4 Scm−1 at room temperature (303K). From the results, this SPE is proposed to have a great potential in future energy storage applications.

The proliferation of portable electronic devices has resulted in an increase of e‐waste that is generated after their use. One of the most hazardous components in e‐waste are batteries, due to their content of heavy metals and toxic chemicals. Fuel cells and redox flow batteries have been recognized as more sustainable alternatives to Li‐based batteries for powering portable applications. Although they provide comparable energy and power densities, they still face some challenges because they rely on proton exchange membranes based on nonenvironmentally friendly, high‐priced perfluorosulfonic acid copolymers that require energy‐intense manufacturing and recycling procedures. In this work, eco‐friendly and sustainable biopolymer electrolyte membranes (BioPEMs) are synthesized from biopolymers like chitosan, cellulose, and starch. These BioPEMs bring forth advantages in performance, sustainability, and cost. Additionally, they present good chemical and mechanical stability, high ionic conductivity in the same order of magnitude as Nafion membranes. Two alternatives of cellulose–chitosan based BioPEMs are successfully applied into primary redox batteries using benign eco‐friendly redox chemistries, delivering open circuit voltages above 0.75 V and power output up to 2.5 mW cm−2. These results demonstrate BioPEMs capability to improve biodegradable batteries in sectors requiring a transient electrical energy, such as environmental monitoring, agriculture, or packaging.
