A new membrane was synthesized containing pure alginate, crosslinking agent (CaCl 2 ), and plasticizer (glycerol). Characterization studies of the membrane were applied to determine the characteristics and morphology using field emission scanning electron microscope, EDX, FTIR, XRD, and atomic force microscopy analysis. The half-cell performance test of the membrane was verified by several tests, including proton conductivity and methanol permeability. The best membrane had high proton conductivity (10.1 3 10 23 S cm 21 ) and very low methanol permeability (1.984 3 10 27 cm 2 s 21 ), which consequently resulted in very high selectivity (5.0907 3 10 4 Ss cm 23 ). Glycerol had a positive modification and good influence on the alginate characteristics. Furthermore, the poor mechanical properties of the alginate biopolymer were enhanced by calcium chloride and glycerol inside the polymer. V C 2018Wiley Periodicals, Inc. J. Appl. Polym.

“…This reduction in conductivity is also thought to be caused by the aggregation of ions that reduce the amount of charge carriers and limit the movement of ions [32]. This reason was also previously reported [33], which said that the empirical formulas-associations by ions cause less chargecarrying motion and form larger ion clusters that limit ionic motion, thus causing ionic conductivity to decrease. In Table 1.…”

Lithium-ion batteries (LIBs) are favorable power source devices at the last two decades, owing to high energy density, rechargeable, long life cycle, portable, safe, rechargeable, good performance and friendly environment. To support their development, in this research has been successfully prepared polymer electrolyte membrane, a main component of LIBs, based on 1-ethyl-3-methylimidazolium acetate ([EMIm]Ac) ionic liquid-plasticized methyl cellulose/lithium perchlorate (MC/LiClO4).[EMIm]Ac ionic liquid was easy synthesized by metathesis reaction between 1-ethyl-3-methylimidazolium bromide ([EMIm]Br) ionic liquid and potassium acetate (CH3COOK) at ambient temperature, for 1 hour.[EMIm]Ac ionic liquid was functional groups analyzed with Fourier Transform Infra-red (FT-IR) and structural analyzed with 1 H-Nuclear Magnetic Resonance (NMR) and 13 C-NMR.[EMIm]Ac ionic liquidplasticized MC/LiClO4 biopolymer electrolyte membrane was prepared by casting solution, with [EMIm]Ac ionic liquid content, 0, 5, 10, 15, 20, 25, and 30% (w/w). Effect of 15% (w/w) [EMIm]Ac ionic liquid incorporation to MC/LiClO4 showed the best condition and selected as the optimum condition with conductivity, tensile strength, elongation break, and thermal stability of 9.160×10 -3 S.cm -1 , 24.19 MPa, 36.43%, ~256 and ~370 ºC, respectively. These results confirm that [EMIm]Ac ionic liquid can plasticize biopolymer electrolyte membranes of MC/LiClO4 to be appealing performances to fulfill the LIB's separator requirement.

“…The development of polymer electrolytes based on biodegradable polymers such as cellulose [1][2][3], starch [4,5], agar [6,7] and carrageenan [8][9][10] has been greatly proposed in these recent years. Besides being abundant, cost effective, non-toxic and environmentally friendly, the natural polymers have been reported to show enhanced chemical and physical properties, good ionic conductivity, high thermal stability, and high level of mechanical strength [1][2][3][4][5][6][7][8][9][10].…”
