1,149,307. Current collector-terminal strip assemblies for electric cells. GENERAL ELECTRIC CO. 7 April, 1967 [8 April, 1966], No. 16036/67. Heading H1B. The current collector 1 of an electrode assembly is a conductive sheet 5 folded to form a plurality of troughs 7 opening from one face forming a plurality of projections on the opposite face and has a compacted powder electrode interlocking with the projections and a terminal strip 3 fitted into at least the trough of a fold. A compacted powder electrode is formed on the current collector 1 with the terminal strip 3 folded in as shown in Fig. 1. After the compacted electrode current collector assembly is removed from the mould the strip 3 is folded out as shown in Fig. 3. Slit 15 (Fig. 1) enables the strip 3 to be folded out to nearly twice the diameter of the electrode. The strip can be fixed into the trough by crimping, soldering, riveting, adhesively or merely held by friction. A silver-zinc cell 21 (Fig. 3) is described with two layers 37, 39 of polypropylene felt adjacent the zinc electrode 31 and two layers 41, 43 of a fabric-supported vinyl-acrylic membrane of controlled pore size separated therefrom by a regenerated cellulose sheet 45, layers 37, 39, 41, 43 forming a capillary matrix for the alkaline electrolyte. |
