(JP6068865-A)      In an electrical contact device for one or more 1-50 microns thick anode foils of a lithium battery with a polymeric electrolyte, (i) at least one anode foil side edge extends beyond the corresp. edges of the cathode and its collector to form a border zone; and (ii) the contact device comprises a rigid metal layer which is compatible with lithium and which is in electrical contact with the side edge of the anode foil, but which is not in electronic contact with other cell components, the layer forming the external terminal of the battery in the unassembled condition.    Also claimed are (a) multilayer polymeric electrolyte batteries provided with the above contact device; and (b) process for prepn. of the contact device.    USE/ADVANTAGE -   The contact device is used in wound or stacked multilayer lithium batteries. It has low resistivity, is compact, is chemcially stable on ultra thin lithium anode foils, provides efficient heat exchange between the battery and external casing and allows mfr. of reliable, economical, ultra-thin polymeric electrolyte batteries.    (US5415954-A)      A polymer electrolyte Li generator comprises at least one multilayer electrochemical cell. Each layer of the cell comprises a laminated combination of at least part of an Li base strip 1-50 um thick constituting the anode, an anode collector, a cathode and a cathode collector, with a polymer electrolyte between the anode and cathode. The cathode and electrolyte are also in strip form. In each layer, at least one edge of the anode extends beyond the corresp. edges of the cathode and collectors to form anode projections, equal in number to the number of the layers. The electrical contact outlet device for the anodes is a metal layer consisting of at least one rigid metal compatible with Li (Cu, Ni, Fe or their alloys) and in electrical contact with the entire extending edges of the anodes at one end of the cell, through the anode projections. The cell is in a coiled, stacked or zig-zag arrangement.    ADVANTAGE -   Reliable, ultra thin polymer electrolyte generator.
