Abstract
Abstract A method of constructing multicell batteries includes placing intermittent deposits of electrodes along Zones No. 1, No. 2 and No. 3. Zone No. 1 is defined as a composite of a first continuous strip of electrically conductive plastic and a second continuous strip of electrically conductive material; intermittent deposits of positive electrodes are placed on the plastic side of Zone No. 1. Zone No. 2 is defined as a composite of a first continuous strip of electrically conductive plastic and a second continuous strip of electrically conductive material; intermittent deposits of negative electrodes are placed on the plastic side of Zone No. 2. Zone No. 3 is defined as a continuous strip of electrically conductive plastic; intermittent deposits of positive and negative electrodes are placed along Zone No. 3, each deposit of positive electrode being on the other side of a Zone No. 3 from and substantially opposite a deposit of negative electrodes. The continuous Zones with the electrodes deposited thereon are collated so that at least one Zone No. 3 is between a Zone No. 1 and a Zone No. 2, so that the electrically conductive plastics in Zone No. 1 and No. 2 are facing the inside of the collation, and so that a deposit of positive electrode on one Zone is opposite a deposit of negative electrode on an adjacent Zone. A separator and electrolyte is placed between each adjacent pair of electrodes in the collation, after which the Zones are sealed together around and between the electrode deposits. Zones No. 1, No. 2 and No. 3 may be structurally connected portions of a continuous web while the electrodes are being applied, in which case the web is cut to structurally disconnect the Zones after electrode application. Alternatively, Zones No. 1, No. 2 and No. 3 may be structurally unconnected during electrode application. The second continuous strips of electrically conductive material which are members of the composites in Zones No. 1 and No. 2 may be: foils of metals such as steel, aluminum, lead or zinc; metalized deposits such as flame strays, vapor deposits, sputtering, and others; or films impregnated with metallic or other conductive particles. One of these second continuous strips may be wider than and extend beyond the edge of the conductive plastic strip to which it is joined: the extension is wrapped around the edge of the collation and overlaid above the other composite Zone on the other side of the collation to produce a battery having both terminals on one face.
