Abstract:
Duplex electrodes are constructed by placing intermittent deposits of positive and negative electrodes on opposite sides of a continuous, electrically conductive plastic carrier strip. The duplex electrodes are then assembled into multicell batteries. The assembly preferably occurs while the duplex electrodes are structurally and electrically connected by the continuous plastic carrier strip after which the carrier strip is subsequently cut between duplex electrodes to obtain structurally and electrically unconnected batteries. Alternatively, the carrier strip may be cut between duplex electrodes before those electrodes are assembled into multicell batteries.
Abstract:
A battery sealant carrier is impregnated with adhesive patches each of which is in the form of a closed loop. The surfaces of the adhesive patches rise above the surfaces of the carrier on at least one and preferably both sides of the carrier. The patches are produced by passing the carrier between a pair of applicators, the first of which has a surface that is sufficiently rigid and uncompressible so that it does not deform and the second of which has a surface that is sufficiently elastomeric so that it deforms during adhesive application. Preferably the two applicators apply adhesive to the carrier simultaneously. The adhesive patches applied by the second applicator are preferably applied at a higher viscosity than those applied by the first applicator. Preferably the sealant carrier is also the battery separator material, in which case there is an area of separator material inside each adhesive patch into which the adhesive has not been impregnated; alternatively, the sealant carrier may have a void area inside each adhesive patch, with the void area being provided to receive a piece of battery separator material.
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.
Abstract:
Duplex electrodes are constructed by placing intermittent deposits of positive and negative electrodes on opposite sides of a continuous metal carrier strip having two nonreactive metal sides. In another embodiment, duplex electrodes are constructed by placing intermittent deposits of positive electrodes on the only nonreactive side of the bimetal carrier strip, with the reactive side of the bimetal strip functioning as the negative electrode in the duplex electrode. The duplex electrodes are assembled into multicell batteries. The assembly preferably occurs while the duplex electrodes are structurally and electrically connected by the continuous metal carrier strip; the carrier strip is then subsequently cut between duplex electrodes to obtain structurally and electrically unconnected batteries. Alternatively, the carrier strip may be cut between duplex electrodes before those electrodes are assembled into multicell batteries.
