Abstract

Electrical contact outlet for an anode sheet of a lithium generator with polymer electrolyte, consisting of one or more multilayer electrochemical cells. The cell comprises at least one lithium base sheet having a thickness between about 1 and 50 microns to constitute the anode and its collector and additionally includes a cathode and its collector as well as the polymer electrolyte. A lateral end of the anode sheet extends beyond corresponding ends of the cathode and the collector to constitute a projecting zone. A metallic layer consisting of at least one rigid metal which is compatible with lithium is in electrical contact with the lateral end of the anode sheet but without electronic contact with the other components of the cell. The metallic layer constitutes the external terminal of the generator when the latter is in non-finished condition. According to a variant, a conductive and cohesive intermediate metallic zone, which consists of lithium or lithium rich ductile alloys is in intimate contact with the lateral end of the anode sheet and the metallic layer mentioned above is therefore in electrical contact with the lateral end of the anode sheet by means of the intermediate zone of lithium. Generators provided with such contact outlet as well as a process for the preparation of these contact outlets are described.
