| Abstract: | We report properties of lithium-intercalated MoO3 crystalline and thin-film which are potential cathode materials for high energy density batteries. Discharge and charge reactions of MoO3 electrodes in a non-aqueous Li+-electrolyte have been studied. The kinetically accessible discharge range amounts to 0 x1.5 for Li insertion in Li
x
MoO3. Transport parameters such as the Li+ chemical diffusion coefficient, thermodynamic factor and ionic conductivity are investigated during the Li+ insertion process and discussed with respect to the crystallinity of the cathode material. |
