Abstract

The separator is an important component in lithium ion batteries which is placed between the anode and cathode which serves to keep the electrodes from coming into direct contact to prevent electrical short circuits. Lithium ion battery separators are generally made of polyvinylidene fluoride (PVDF), polyacrylonitrile (PAN) polymer which has high ionic conductivity and good mechanical properties. However, these polymers and materials still have many weaknesses and modifications are needed to develop them. This study aims to see the effect of adding new polymers to the components of the separator. The new polymer used in this modification is cellulose, the cellulose derivative used is cellulose acetate. Cellulose acetate used is cellulose acetate of oil palm empty fruit bunches. The advantages of using cellulose acetate are low cost, selective adsorption, soluble in most solvents (especially organic solvents), hydrophilic and made from renewable sources. The separator was made by reflux method, the separator was made by mixing 5.6 g of PVDF, 0.7 g of Al(OH)₃ with variations of CA 0.1, 0.2 and 0.3 g. The tests carried out are thickness test, elongation test and PSA test. Based on the results of the tests conducted, the separator is feasible to use and meets the standards.
