A compsn. allowing the fabrication by rolling of anodes made from alkali metals or their alloys, comprising at least one solvent and a non-volatile additive serving as rolling lubricant, the additive being compatible with Li and comprising at least one sequence of formula L-Y-S in which L = a hydrocarbon radical with more than 8C serving as lubricant segment, S - an oligomeric segment contg. O or N heteroatoms capable of solvating metallic salts and providing the additive with electrolytic conductivity, and Y = a bond or a chemical bridging gp. between the hydrocarbon segment L and the oligomer segment S.
