“…Samples of plasticized chitosan-based polymer electrolytes were obtained by Arof et al ,, The authors showed that chitosan plasticized with 50 wt% of ethylene carbonate and the samples plasticized with 10 wt% of oleic acid showed the ionic conductivities of 10 −5 S cm −1 . The authors of the present paper studied polymer electrolytes based on starch and hydroxylethyl cellulose , plasticized with 30−48 wt% of glycerol and ethylene glycol, respectively. The best samples showed very good ambient temperature ionic conductivity of 10 −3 S cm −1 .…”

“…The utilization of these residues can minimize the problem connected with their accumulation and the use of traditional materials. Following these trends, electrolytes based on natural polymers such as starch, 5 cellulose derivatives, 6 chitosan, 7 rubber, 8 and gelatin 9 are proposed. These polymers after physical and chemical modifications can be obtained in the transparent membrane form with very good adhesion properties to steel or glass.…”

Polymer electrolytes were obtained by the casting technique from a solution containing chitosan, hydrochloric acid, and plasticizer such as glycerol, ethylene glycol, and sorbitol. The transparent membranes with good ionic conductivity properties were characterized by impedance and UV-vis spectroscopies, thermal analysis (DSC), and X-ray diffraction. The best ionic conductivity values of 9.5 x 10(-4) S cm(-1) at room temperature and 2.5 x 10(-3) S cm(-1) at 80 degrees C were obtained for the sample containing 59 wt% of glycerol and an equimolar amount of HCl with respect to NH2 groups in chitosan. The temperature dependence of the ionic conductivity exhibits an Arrhenius behavior with activation energy of 16.6 kJ mol(-1). The thermal analysis indicates that both glass transition temperature (-87 degrees C) and crystallinity are low for this electrolyte. The samples with 13 wt% of LiCF3SO3 showed that the ionic conductivity values of 2.2 x 10(-5) S cm(-1) at room temperature and 4 x 10(-4) S cm(-1) at 80 degrees C are predominantly amorphous and showed a low glass transition temperature of about -73 degrees C.

“…The starch has also been blended with other polymers such as PEO, chitosan, poly(styrene sulphonic acid), PVA, and methyl cellulose. The initial study concerning starch-based electrolyte was reported by Pawlicka et al in 2002 for a corn starch/LiClO4/glycerol system [14]. Aside from glycerol, other types of plasticizers have been used, such as glucose, sorbitol, urea, formamide, glutaraldehyde, and ethylene carbonate.…”

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.
