“…[13] The difference in mechanical properties between CMC of commercial cellulose and CMC of Nias' cacao pod husk is affected by the crystallinity index and molecular weight as previously explained above. The crystallinity of CMC of ChemistrySelect commercial cellulose is higher than that of the CMC of Nias' cacao pod husk, in addition, the molecular weight of CMC of commercial cellulose [36] is higher than the CMC of Nias' cacao pod husk as explained above. However, the tensile strength of the CMC of Nias' cacao pod husk shows almost similar to previous research which was applied as packaging.…”

“…The polymer electrolyte is preferred to change the liquid electrolytes with some drawbacks such as volatile, poor tensile strength, and corrosive [37] . Biopolymers are widely studied has the potential to fabricate solid electrolytes, including cellulose derivatives such as MC and CMC [36] . Both MC and CMC dissolve into water and can form a transparent film.…”

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.

Chemical modification of Sulfonated poly(arylene ether ketone) with carboxylate acid side chain (C-SPAEK) membranes has been conducted through partially substitution of the 4,4-bis(4hydroxyphenyl)-valeric acid (DPA) with 4,4-bis(4-hydroxyphenyl)-propane (BPA) at varies different compositions of sulfonate. FTIR and EDS analysis of the synthesized SPAEK revealed the presence of carboxylic acid, methyl, sulfonate groups and aromatic ether bonds in the SPAEK membrane. The effect of different compositions of carboxylic acid and sulfonate groups on mechanical strength, thermal stability, oxidative stability, water absorption, swelling ratio and proton conductivity of the membranes was studied. The SPAEK-50/50 membrane exhibits superior properties with high mechanical strength, high thermal and oxidative stability, good water absorption, low swelling ratio, high dimensional stability and has a proton conductivity at 80 °C of 0.102 S/cm close to the Nafion-117 membrane of 0.120 S/cm. This finding confirms that the partial substitution of the hydrophilic monomer of DPA with 50 % mole of BPA with a sulfonate group composition of 50 % resulted in an excellent SPAEK membrane.

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.
