1364628 Metal-air batteries JOSEPH LUCAS (INDUSTRIES) Ltd 15 Nov 1971 [21 Nov 1970] 55519/71 Heading H1B In a method of making a metal-air battery a strip 11 of micro-porous P.T.F.E. has placed thereon along its centre a narrow band 12 of a polyamide material and layers 13 of catalyst and conductive material, constituting the air electrodes, are applied at intervals to the strip. A strip 16 of porous insulating material, e.g. a polyamide, is placed over the strip 11 and layers 13 and metal anodes 14 having a lead 15 are placed on the strip adjacent the layers 13. The strip 11 is folded along its centre line so that each anode 14 is positioned between a pair of interconnected air electrodes 13. The leads 15 penetrate the strip 16 so that each anode 14 is connected to the pair of cathodes 13 of the following cell. Each cell, comprising an anode 14 and pair of cathodes 13, is formed by heat sealing along lines 17 whereby the polyamide of the strip 16 melts and bonds together the two opposite faces of the strip 11. The strip assembly is now folded as shown in Fig. 2 and placed in a battery casing 22. |
