Abstract
A process for obtaining lithium-based thin sheets, generally used for the production of negative plates for accumulators. The thin sheets are formed by adding magnesium to a bath of molten lithium, transforming the alloy into a solid product in a form suitable for rolling, and rolling the solid product obtained by passing it between steel cylinders a plurality of times at ambient temperature to obtain thin sheets.
