“…Alginate also had been applied in solid biopolymer electrolytes system (SBEs) and doped with ammonium bromide, NH 4 Br. Fuzlin and Samsudin 122 claimed the changes of peak at COO − group of alginate was due to the complexation between alginate and NH 4 Br, that they had been worked on. This impacted to an improvement in the electrolytes amorphous phase and thermal stability of solid biopolymer electrolytes (SBEs) system.…”

The emergence of biopolymers as polymer electrolyte membrane for non-Nafion used fuel cell application in recent years was an impactful finding. This review gives a different approach to researchers, by exposing the characterization analysis perspectives of developed materials from biomass sourcesalginates, carrageenan, cellulose, chitosan and polyhydroxyalkanoates. Their membrane performances are proven in this work through chemistry understandings, hence assuring a clear picture to gain information of these biopolymers' behavior as PEM. These five bio-precursor materials are believed to perform as high potential PEM alternatives, thus this study appeared to be an insightful guidance to the industry replacing high cost Nafion membrane to a lower cost membrane sources for future massive production economically benign. HIGHLIGHTS• Biopolymers are one of the promising natural sources to be utilized as the essential PEM in fuel cell • These biopolymers to be highlighted in this review are alginates, chitosan, carrageenan, cellulose and starch • Electronic biopolymers like carbon composites, hydrogels, nucleic acid, polyester, polysaccharide and protein imposed great features with their abundant functional groups, strong electrical conductivity, excellent ion conduction, versatility and stability

With a huge upsurge in the energy requirements all over the world, development of energy storage devices with high safety standards without compromising the ecological aspects has become the need of the hour, that propelled the scientific community to search for alternative yet promising sources of energy that would prevent the exhaustion of natural resources. Numerous attempts have been undertaken to utilize the renewable biopolymers in the evolution of solid‐ state electrolytes, as a substitute for liquid electrolytes which are prone to cause leakage leading to hazardous accidents. Despite strenuous efforts, it is still challenging to strike a right balance between the biopolymer elements and the conducting additives. In this review, we aim to lay out a recap on the progress achieved in recent times by employing biopolymers as electrolyte components and its future prospects, that would assist the researchers across the globe to inch one step closer in their quest to find the best electrolyte system for flexible electronics.

A composite based on natural polymer xanthan gum (XG) and expanded graphite nanosheets (GNs) was prepared for application as a flexible and ecofriendly solid polymer electrolyte (SPE). To evaluate the ionic conductivity, electrochemical impedance spectroscopy was performed at different temperatures, ranging from 25 to 80 C, reaching high values of 1.1 Â 10 À3 and 2.43 Â 10 À3 S cm À1 at room temperature and 40 C, respectively, for the sample containing 0.5% by weight of GNs. Additional characterizations including X-ray diffraction, scanning electron microscopy, transmission electron microscopy, ultraviolet-visible spectroscopy, Raman spectroscopy, Fourier transform infrared spectroscopy, thermogravimetric analysis, and cyclic voltammetry were implemented to get full structural, morphological and optical relevant features of these samples. The results showed that flexible SPEs based on XG/GNs are very promising and can be used as electrolytes with high potential of application in a wide variety of electrochemical devices.
