Abstract:
The invention relates to a method for producing an electromechanical bundle for a metal-ion battery, for electrical connection thereof to the output terminals of the battery, characterised by coiling or folding the sides of at least one of the two electrodes on itself, then compacting by packing in order to further increase the density of the coiled sides in order to weld the electrode to a current collector.
