Sintesis dan Karakterisasi Membran Kitosan/LiOH sebagai Elektrolit Padat Baterai Sekunder

Abstrak

The synthesis and characterization of chitosan/LiOH membranes was carried out aimed to determine the effect of  chitosan/LiOH on the electrolyte membrane microstructure of secondary batteries. Synthesis of chitosan/LiOH membranes was carried out by casting method with concentration variations w/w LiOH. The characterization was carried out using FTIR (Fourier Transform Infra Red) and SEM (Scanning Electron Microscopy). The results FTIR of chitosan/LiOH membrane showed an interaction between chitosan/LiOH. At a wavelength of 3500 nm a new -OH functional group is formed and at 1500-945 nm a bending bond is formed between the -OH group and –NH₃. The SEM results show that agglomeration is formed by increasing the concentration of LiOH in the solution. A distribution of homogeneous particles occurs on the surface of the membrane. This shows that there is the effect of adding LiOH to the formation of membranes which results in increasingly tenuous / unstable atomic bonds and increasingly conductive materials.
