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 FLAT CELL BATTERY HAS A WRAPPER CONSISTING OF TWO PIECES, EACH OF WHICH IS IN CONTACT WITH AN END ELECTRODE SO AS TO SERVE AS A BATTERY TERMINAL. ONE OF THESE WRAPPER PIECES OR A LAMINATED LAYER THEREOF IS WRAPPED AROUND THE EDGE OF THE BATTERY AND OVERLAYS THE OTHER WRAPPER PIECE TO PRODUCE A BATTERY HAVING BOTH TERMINALS ON ONE FACE. PREFERABLY THE WRAPPER PIECES ARE LMINATES OF METAL AND ELECTRICALLY CONDUCTIVE PLASTIC, WITH THE PLASTIC BEING IN CONTACT WITH THE END ELECTRODES AND AN EXTENSION OF THE METAL IN THE LAMINATE SERVING AS THE TERMINAL WHICH IS WRAPPED AROUND THE EDGE OF THE BATTERY, THE WRAPPED AROUND EXTENSION, WHICH MUST BE ELECTRICALLY INSULATED FROM THE WRAPPER PIECE OVER WHICH IT IS OVERLAID, MAY BE SECURED TO THE OTHER WRAPPER PIECE BY NONCONDUCTIVE ADHESIVES OR HEAT SEALS.
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:
A BATTERY HAS A WRAPPER CONSISTING OF TWO PIECE SEALED AROUND THEIR PERIMETERS. EACH WRAPPER PIECE COMPRISES A LIMITE OF METAL AND ELECTRICALLY CONDUCTIVE PLASTIC, THE CONDUCTIVE PLASTIC IN EACH OF THE LAMITES BEING IN CONTACT WITH AN END ELECTRODE WITHIN THE BATTERY. THE WRAPPER PIECE ARE CLOSED AROUND THEIR PERIMETERS TO PREDUCE A LIQUID IMPERIOUS SEALED BATTERY. PREFERABLY, THE METAL IN EACH OF THE TWO WRAPPER LAMINATES COMPRISES A FOIL OF STEEL. THE LAMINATED WRAPPER PIECES MAY BE USED TO ENCLOSE EITHER MULTI-CELL OR SINGLE CELL BATTERIES.
Abstract:
A DEPLEX ELECTRODE IS CONSTRUCTED BY FIRST COATING BOTH SIDES OF A CONTINUOUS METAL CARRIER STRIP WITH ELECTRICALLY CONDUCTIVE ADHESIVE MATERIAL AND THEN PLACING INTERMITTENT DEPOSITS OF POSITIVE AND NEGATIVE ELECTRODES ON OPPOSITE SIDES OF THE COATED CARRIER STRIP. THE DUPLEX ELECTRODE IS THEN ASSEMBLED INTO A MULTICELL BATTERY. THE ASSEMBLY PREFERABLY OCCURS WHILE THE DEPLEX ELECTRODES ARE STRUCTURALLY AND ELECTRICALLY CONNECTED BY THE CONTINUOUS CARRIER STRIP FTER WHICH THE CARRIER STRIP IS SUBSTANQUENTLY CUT BETWEEN DEPLEX 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. PREFERABLY, THE CARRIER STRIP IS ZINC, ALUMINUM, OR STEEL.
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.
