Method of preparing a negative electrode including lithium alloy for use within a secondary electrochemical cell. [Li--Al/KCl--LiCl/FeS]

A negative electrode that includes a lithium alloy as active material is prepared by briefly submerging a porous, electrically conductive substrate within a melt of the alloy. Prior to solidification, excess melt can be removed by vibrating or otherwise manipulating the filled substrate to expose interstitial surfaces. Electrodes such as solid lithium--aluminium filled within a substrate of metal foam are provided. 1 figure, 1 table.
