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:
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. The metal carrier strip may comprise: (1) a unimetal which is nonreactive to the positive and negative electrodes and to the electrolyte within the battery; (2) a bimetal in which the metal adjacent the positive electrode is nonreactive with respect to that electrode and the metal adjacent the negative electrode is nonreactive with respect to that electrode; (3) a trimetal whose outer two layers are nonreactive as in (2); and, (4) a bimetal or trimetal in which the metal adjacent the positive electrode is nonreactive with respect to that electrode and in which the other metal functions as the negative electrode in the battery. The particular metals employed will depend upon the electrochemical system used in the battery.
Abstract:
A thin, flat, multicell battery comprising a multiplicity of electrically conductive layers arranged in cooperative electrical association with one another to provide a plurality of cells. The layers include intercell connectors which cooperate together to form sealed enclosures for each cell, and to form electrical connections to connect the cells in series. The battery has a minimized internal resistance, a capability for high discharge rates particularly suitable for the production of pulses of current, and a discharge efficiency far superior to conventional flat cell batteries at current densities exceeding 100 milliamperes per square inch of anode. These features are achieved by the adherence and electrical bonding one to the other of the confronting faces of the several conducting layers of the battery. The preferred form of the battery is discussed in terms of the LeClanche system.
Abstract:
GIH-01 A HOLE IN THE TOP OF A BATTERY IS COVERED BY A GAS PERVIOUS, LIQUID IMPERIOUS MEMBER SECURED TO THE TOP IN A MANNER WHICH PROVIDES A LIQUID-TIGHT CLOSURE AROUND THE HOLE. THE GAS PERVIOUS, LIQUID IMPERIOUS MEMBER MAY BE EXTENDED TO AND AROUND THE EDGE OF THE TOP WHERE IT IS CRIMPED BY THE CONTAINER AND WHERE IT FUNCTIONS AS A GROMMET TO PROVIDE A LIQUID TIGHT- CLOSURE AROUND THE OERIMETER OF THE TOP. THE GAS PERVIOUS, LIQUID IMPERIOUS MEMBER MAY BE CRIMPED BETWEEN THE TOP AND AN ELECTRICCALLY CONDUCTIVE CONTACT MEMBER WHICH IS SECURED TO THE TOP. CONSTRUCTIONS ARE ILLUSTRATED IN WHICH THE GAS PERVIOUS, LIQUID IMPERIOUS MEMBER IS ELECTRICALLY NONCONDUCTIVE, WHILE OTHER CONSTRUCTIONS ARE SHOWN IN WHICH THE MEMBER IS CONDUCTIVE.
