Li2SnO3 has been synthesized by the sol-gel method using acetates of lithium and tin. The Li2SnO3 precursor was then characterized by thermogravimetric analysis (TGA) and X-ray diffraction (XRD) to determine the suitable calcination temperature and confirm the formation of Li2SnO3. The chemical diffusion coefficient of lithium ion, in Li2SnO3 was determined from two different electrochemical methods i.e. cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The of Li2SnO3 obtained from CV technique was 1.31 x 10(-10) cm(2) s(-1) whereas the determined from EIS analysis were in the range from 10(-12) to 10(-14) cm(2) s(-1) for Li2SnO3 cell at different cycles.
