The formation of lithium-aluminum alloys at pure aluminum has been studied by potentiostatic, ac impedance, and galvanostatic techniques. It is concluded that /beta/-LiAl is formed under most circumstances, some degree of nonstoichiometry being evident from the polarization curves. The diffusion coefficient for Li in /beta/-LiAl was also determined in the temperature range O to -40/sup 0/C Cycling efficiencies of the alloy electrode with respect to both lithium and aluminum were also investigated. 21 refs.
