Characterization of Solid Polymer Electrolyte Membrane made of Methylcellulose and Ammonium Nitrate

Abstract

Nowadays, the application of portable electronics devices such as smartphone, notebook and tablet playing important role in daily life. This portable electronic devices required portable powering sources such as battery. However, the current battery technology containing liquid electrolyte which is hazardous and harmful when leaking. Therefore, the major purpose of this study was to propose a new biodegradable, safe and low cost solid polymer electrolyte (SPEs) mainly from Methylcellulose (MC) doped Ammonium Nitrate (AN). The study was conducted by using casting method as it is the most appropriate technique due to its simplicity and low cost. Methylcellulose (MC) as the host was doped with different weight percentage (wt%)of Ammonium Nitrate (AN) to fabricate SPEs. The result shows the adding of AN onto MC was significantly enhanced the physical properties of SPEs. The loading of 2g MC with 25% AN (MC2_25AN) yield the highest conductivity at 3.5 × 10−7 Sm−1 at room temperature. Furthermore, the MC2_25AN poses a good stability with the lowest swelling rate. Therefore, the use of low cost and biodegradable MC and AN have a great potential to replace the hazardous electrolyte in electrochemical powering sources.

Synthesis and Characterization of Polymer Electrolyte Membrane Based on Cellulose-Chitosan-Alginate as Li-Ion Battery Separator

“…The results of cross-sectional SEM analysis showed differences in the membrane microstructure according to Chitra et al [27], stating that a high pore density indicates many pores with a large surface area. The less-dense the membrane structure, causes more water is absorbed, and this supports the process of ion exchange mechanisms that occur in the membrane [28]. From this statement, the morphological results on the membrane can affect the physical and mechanical properties of the polymer electrolyte gel membrane (GPE) regarding the value of tensile strength and elongation, that the denser the matrix on the membrane, the fewer cavities are produced, and the elongation value is small as shown in Figure 5 (a) HEC: SA variation.…”

“…The conductivity increased to  ´--3.12 0.58 10 S cm ( ) Ammonium nitrate (NH 4 NO 3 ) possesses low lattice energy (648.9 kJ mol −1 ) compared to other ammonium salts such as ammonium chloride (NH 4 Cl), and ammonium bromide (NH 4 Br) are 698 kJ mol −1 and 665 kJ mol −1 , respectively [59]. It has been proven that NH 4 NO 3 can increase the conductivity of polymer hosts, for example, methylcellulose [9], and polyvinyl alcohol [34], from 10 −11 and 10 −9 , respectively, to 10 −5 S cm −1 . As more salt is added to the solutions, more charge carriers are provided to conduct ions, thus increasing the conductivity [26,60,61].…”

“…It has been reported that liquid electrolytes have leakage issues, corrosion of electrodes, limited temperature range of operation, hermetic sealing issues and battery internal short circuits [2,[6][7][8]. In addition, the continuous demand for environmentally friendly energy solutions necessitates the investigation of new energy storage materials [9]. Aziz et al [10] and Hamsan et al [11], using chitosan and dextran, respectively, have shown the potential use of a bioactive and non-toxic biopolymerbased electrolyte in the manufacture of electrochemical devices, which could overcome the drawbacks of toxic synthetic polymers.…”

“…However, this magnitude is insufficient for practical use in SPEs’ technology. By modifying the chemistry of MC, it has shown promising ionic conductivity in the amorphous phase, allowing for better ion transport inside the polymer [ 6 , 19 ]. According to previous reports [ 20 , 21 ], blending polymers improves the electrochemical and physicochemical properties of the electrolyte system by expediting the ion migration process and providing additional complexation sites within the polymer matrix.…”
