Description
Summary:In this dissertation, the lithium ions chemical diffusion coefficients (Du) for lithium vanadium pentoxide (LixV20 5 ), in different voltages, were determined by two methods, cyclic voltammetry (CV) and Galvanostatic intermittent titration technique (GITI). In CV method, three values were obtained in anode peaks, and for GITI we only calculate one. The order of all determined values were 10-10 cm2 s-1 , higher than most lithium oxide.
