“…69 Table 3 shows a comparison of the ionic conductivity obtained in this work with the ionic conductivity obtained from previous work. The highest ionic conductivity obtained in this work, that is, CMC/CMCh (80/20) + 20 wt% LiOAc was compared with the other optimum ionic conductivity reported in some previous research such as CMC + 35 wt% DTAB, 10 CMC + 25 wt% NH 4 Br, 60 CMC + 50 wt% AFT, 61 CMC/PVA + 6 wt% NH 4 Cl, 62 CMC/PVA + 6 wt% NH 4 Cl, 62 MC + NH 4 NO 3 + PEG, 63 and PVA + LiClO 4 + TiO 2 . 64 Based on the comparison, it can be stated that SPE membranes of CMC/CMCh (80/20) with various weight percentages of LiOAc have higher potential contributing conductivity.…”

Carboxymethyl cellulose (CMC) is one of the important cellulose derivatives, and it can be developed as a host polymer for solid polymer electrolyte (SPE) membrane. This study aimed to synthesis of CMC from coconut fiber cellulose and it was applied to prepare the SPE membranes. Cellulose isolation was conducted through the delignification and bleaching process, while the CMC synthesis was conducted through alkalization and carboxymethylation treatments. SPE membranes were prepared by blending CMC with carboxymethyl chitosan (CMCh) (80/20) and mixed with various weight percentages of LiOAc at room temperature. SPE membranes characterizations were conducted using FTIR, EIS, XRD, SEM, and tensile testing. Cellulose and CMC yields were 23.1% and 65.44%, respectively. Incorporating 20 wt% LiOAc into the CMC/CMCh (80/20) SPE membrane yielded the highest ionic conductivity of 1.37 × 10−3 S/cm.

Modification of Nias’ Cacao Pod Husk Cellulose through Carboxymethylation Stages by Using MAOS Method and Its Application as Li‐ion Batteries’ Biopolymer Electrolyte Membrane**

This research aimed to modify the Nias' cacao pod husk cellulose by using Microwave-assisted Organic Synthesis (MAOS) method to produce carboxymethyl cellulose and its application as lithium-ion batteries' biopolymer electrolyte membrane. There were two main stages of modification of Nias' cacao pod husk cellulose i. e. cellulose alkalization and cellulose carboxymethylation process (etherification stage). Lithium-ion batteries' biopolymer electrolyte membrane was fabricated through the casting solution technique, where the blend of Methylcellulose/Carboxymethyl cellulose (MC/CMC) (80/20) (w/w) was complexed to 10 % (w/w) of lithium perchlorate. The determinations of functional groups, molec-ular structure, crystallinities, and thermal stability were conducted using Fourier Transform Infrared, Nuclear Magnetic Resonance, X-Ray Diffraction, and Thermogravimetry Analysis, respectively. The lithium-ion biopolymer electrolyte of the 10 % lithium perchlorate-complexed MC/CMC (80/20) blend shows ionic conductivity, tensile strength/elongation at break, thermal stability are 5.91 × 10 À 3 S cm À 1 , 30.69 MPa/31.83 %, and 279.40-341.05 °C. Based on the results, the prepared biopolymer electrolyte of 10 % lithium perchlorate-complexed MC/CMC (80/20) fulfills the separator (solid electrolyte) requirement for lithium-ion battery application.

This work aimed to prepare solid polymer blend electrolytes based on carboxymethyl cellulose (CMC) and carboxymethyl chitosan (CMCh) complexed with lithium acetate (LiCH3COO) for lithium‐ion batteries application. The solid polymer blend electrolytes of LiCH3COO‐complexed CMC/CMCh (50/50) polymer blend electrolyte were prepared by using the casting solution technique, where various weight percentages of LiCH3COO were mixed into CMC/CMCh (50/50) blend as host polymer. Solid polymer blend electrolytes of CMC/CMCh + 30wt% LiCH3COO had the highest ionic conductivity as much as 2.24 × 10−5 S cm−1 among others. The CMC/CMCh blend (50/50) + 30wt% LiCH3COO degraded at temperature interval 256–473°C. Linear sweep voltammetry method shows that CMC/CMCh (50/50) + 30wt% LiCH3COO reached a decomposition voltage around 2.54 V, while CMC/CMCh (50/50) + 10wt% LiCH3COO was decomposed at a lower voltage around 1.55 V. Based on the transference number measurement appeared that the initial and final current values of 0.84 for the CMC/CMCh (50/50) + 30wt% LiCH3COO is higher than that of the CMC/CMCh (50/50) + 10wt% LiCH3COO (0.8). Based on the results obtained, it can be concluded that the CMC/CMCh blend (50/50) + 30wt% LiCH3COO meets the minimum requirements for the main parameters of ion conductivity and thermal stability as a solid electrolyte polymer membrane but needs improvement and attention to its mechanical properties.Highlights CMC and carboxymethyl chitosan (CMCh) have polar groups for ionic conduction. The CMC/CMCh blend (50/50) + 30wt% LiCH3COO has good ionic conductivity of 2.24 × 10−5 S cm−1. The CMC/CMCh blend (50/50) + 30wt% LiCH3COO has high thermal stability 256–473°C. The CMC/CMCh blend (50/50) + 30wt% LiCH3COO has high decomposition voltage around 2.54 V. The CMC/CMCh blend (50/50) + 30wt% LiCH3COO has higher transference number (0.84).
