Chitin nanofibres (CNF) are synthesized from a biopolymer chitin by ultra-pure chemical curing method. The nanocomposite solid polymer electrolytes (CSPE) based on PEO-LiBOB with chitin nanofibres as inert nanofiller are prepared by membrane hot-press method. The polymer membrane obtained is subjected to various electrochemical studies such as impedance analysis, cyclic voltammetry and compatibility studies. The crystalline behavior and structural changes in CSPE are investigated by means of XRD and FT-IR analyzes. The filler incorporated membrane shows better electrochemical properties as compared to filler free membrane. The addition of chitin nanofibre in polymer matrix enhances the ionic conductivity and achieves a maximum of 10-3.8 S/cm. Cyclic voltammetry study is used to know the electrochemical activity of prepared polymer electrolytes at ambient temperature. The compatibility studies reveals that the filler incorporated nanocomposite solid polymer electrolytes reduce the value of interfacial resistance (Ri) and it is better compatible with lith- ium interface.
