Synthesis and characterization of chitosan - LiClO4 solid electrolyte membrán and its application in batteries

Abstract

The Synthesis of chitosan - LiCLO4 solid electrolyte membrane has been carried out. The membrane is prepared by using a casting method. Chitosan 0.6 gram, LiClO4 (Sigma-Aldrich > 95%) with variations of 10% and 40% (w / w) and 10% PVA (w / w) put into the measuring cup. Furthermore, the mixture was dissolved in a 2% acetic acid solution of 30 mL (v / v) and stirred evenly at room temperature. The solution is then put into an acrylic casting plate measuring 30x5 cm and allowed to stand dry. The electrolyte membrane was then analyzed for functional groups using FTIR and conductivity using the HICRI 3532-50 Hi-Tester LCR. The FTIR results stated that the addition of lithium caused a shift in the wave number 2871 to 2920 cm-1 which showed the presence of the OCH3 group, while the highest conductivity value was 3.98 x 10-7 - 3.16 x 10-6 at a frequency of 42 Hz - 5MHz. These results provide information that the synthesized membrane can be applied as an electrolyte membrane on the batteries.
