Cellulose acetate biopolymer electrolyte from oil palm empty fruit bunch doped with LiClO4 was synthesized by solution casting method. Structural properties of this biopolymer electrolyte were characterized by Fourier Transform Infra Red (FTIR) and X Ray Diffraction (XRD). Result of FTIR analysis, the addition of LiClO4 caused shifted in wavenumber to the lower wavenumber in C=O functional group and shifted in wavenumber to the higher wavenumber in C-O functional group. Based on the results of XRD analysis, the presence of LiClO4 caused the crystalline phase of cellulose acetate to be a more amorphous phase. These indicated an intermolecular interaction between cellulose acetate and LiClO4 and LiClO4 dissociate in polymer matrix of cellulose acetate. © Published under licence by IOP Publishing Ltd.
