摘要: Abstract The chemical diffusion of lithium ion in Li3V2(PO4)3 were investigated by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) methods. CV results show that there exists a linear relationship between the peak current (ip) square root scan rate (ν1/2). spectrum exhibits single semicircle straight line very low frequency region. A behavior was observed for every curve real resistance as function inverse angular obtained coefficient from EIS measurements varies within 10− 9 to 10− 8 cm2·s− 1, good agreement with those results.
