| Summary: | Daily usages of equipment such as office equipment and household equipment are increasing significantly. These equipments need an energy source, one of common energy source is lithium battery. In this battery contains liquid electrolyte between its anode and cathode. Since the using of lithium battery increase rapidly and lithium battery cannot be naturally decomposed, so it can produce environment pollution. The aim of this research is modifying electrolyte liquid of lithium battery to become biodegradable solid polymer electrolyte. The electrolyte polymer can be naturally decomposed, so that the environment pollution caused by battery waste can be minimized. In this research, the biodegradable solid electrolyte were made from polyethylene oxide (PEO) and 10% LiClO4 with addition of PCL in various compositions. These electrolyte polymers were characterized by functional group analysis using FTIR (Fourier Transform Infra Red), conductivity by EIS (Electrochemical Impedance spectroscopy), thermal analysis by DTA/TGA (Differential Thermal Analysis / Thermo Gravimetry Analysis), crystallinity analysis by XRD (X-Ray Diffraction), and surface morphology by optical microscope. Based on obtained results, the increase of PCL compositions, the conductivity and the degree of crystallinity of electrolyte polymer increase, but their thermal stability decreases. <br />
