n this research, we studied the effects of lithium doping on the transport properties of MoO<sub>3</sub> ceramics. A series of lightly lithium-doped MoO<sub>3</sub> ceramics was prepared: 2, 4 and 8 mol% Li-doped MoO<sub>3</sub>. The x-ray diffraction analysis confirmed that the typical MoO<sub>3</sub> structures were retained at the low doping. However, from laser-induced-breakdown spectroscopy, the differences in the peak intensities of the doped samples clearly indicates that lithium ions are successfully incorporated into the lattices in different amounts. To see the effects of the lithium doping on the transport properties in the MoO<sub>3</sub> lattices, impedance spectroscopy is used in the capacitor geometry. A systematic increase in the overall bulk conductivity and a faster relaxation behavior were observed when the doping level was increased. Lastly, when the doping level was increased the activation energy was drastically decreased, which indicates that the lithium facilitates transport along a 2D path.
