FIELD: electronics.
SUBSTANCE: invention relates to connecting lithium electrode to contact lead in rechargeable battery. Electrode comprises sheet or foil of lithium or lithium alloy with tab protruding from an edge of sheet or foil. Contact lead comprises electrically conductive lead with end portion made of second metal that does not alloy with lithium and has plurality of through holes. End portion of contact lead and tab of electrode are positioned so that, there is substantial overlap between end portion and tab. Metal of tab is then caused, for example, by pressing and welding, to penetrate via through holes of end portion so as to join electrode to contact lead.
EFFECT: providing good electrical and mechanical contact between electrode and lead.
