Abstract

The studies of the Li | 1M LiClO4 in propylene carbonate | LixV2O4 cell were carried out. The results of the electrochemical and X-ray investigations indicated that the cathode reaction in this cell proceeds as an intercalation process. Cycling test shows the reversibility of this cell along 35 charge/discharge cycles. However X-ray diffraction of the electrode material shows partial oxidizing of the LixV2O4 phase yielding γ-LiV2O5. The kinetic parameters of this process such as the chemical diffusion coefficient and mobility of lithium in the LixV2O4 were calculated.
