In present work, Al-Li alloys used as lithium-air battery anode material were prepared by solid diffusion method. In the system of molten LiCl-KCl-LiF with molar compositions of 55%-45%-5%, electrolytic reduction of Li-ion on solid aluminum plate was conducted; And Al-Li alloys were formed by the diffusion of metal Li into the plate. The effects of influencing factors, such as electrolysis time, cell voltage and current density, were all studied. The characteristics of Al-Li alloys were analyzed by X-ray diffraction and scanning electron microscopy. It was found that the lithium content of 15%wt. in Al-Li alloys can be obtained by solid diffusion method for 4.0 h with the current density of 0.125 A.cm<SUP>-2</SUP> at 480 °C; and the phase compositions of the Al-Li alloys were alpha- and beta-aluminum lithium from X-ray diffraction analysis.
