Abstract

The cell constitutes an accumulator. It encloses, in a plastic leaktight casing, main electrodes (10 to 13) interleaved with a separator (14), as well as an auxiliary electrode (15). These electrodes are connected respectively to three connection terminals each comprising two collectors (20 and 21) fixed to the inner and outer faces of a wall of the casing and connected by a weld spot (24) passing through a hole (18) in the wall. With a view to avoiding leakages of electrolyte, a thin layer (22, 23) of a fatty acid polyamide is interposed between each collector and the corresponding wall of the casing. <IMAGE>
