Abstract: AROUND EACH CELL OF A MULTICELL BATTERY IS A WINDOW, BOTH SIDES OF WHICH ARE ADHESIVE. THE ISIDE PERIMETER OF EACH WINDOW, WHICH OVERLAPS A PORTION OF THE INTERCELL CONNECTOR BETWEEN TWO ADJACENT CELLS, PROVIDES A FIRST SEAL AROUND A CELL TO PREVENT LIQUID FROM ONE CELL FROM MIGRATING EITHER OT ANOTHER CELL OR TO THE EXTERIOR OF THE BATTERY. THE OUTSIDE PERIMETER OF EACH WINDOW EXTENDS BEYOND THE EDGES OF THE INTERCELL CONNECTOR TO PROVIDE A SECOND SEAL WHICH ALSO PREVENTS LIQUIDS FROM MIGRATING FROM THE INTERIOR TO THE EXTERIOR OF THE BATTERY. THE WINDOWS MAY BE ELECTRICAL INSULATORS WHICH SERVE THE ADDITIONAL FUNCTION OF KEEPING ELECTRICALLY CONDUCTIVE INTERCELL CONNECTORS AND/OR LIQUID IMPERVIOUS LAYERS FROM COMING INOT ELECTRICAL CONTACT WITH EACH OTHER.

Abstract: An electrochemical cell is disclosed having a resistive element interposed between a cell electrode and its corresponding terminal. The resistive element acts as a safety resistor and is a high resistivity material which has a high temperature coefficient of resistance. The element significantly lessens the high flash amperage current which is characteristic of some electrochemical cells, such as nickel-cadmium cells. The resistance of the element preferably has a value as determined in accordance with the equation:

WHERE Ra is the ohmic value of the element; E is the open circuit voltage of the cell; Ii is the initial flash current of the cell in the absence of the element; and Ip is the flash current of the cell with the element present in the cell.

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: DUPLEX ELECTRODES ARE CONSTRUCTED BY PLACING INTERMITTENT DEPOSITS OF POSITIVE AND NEGATIVE ELECTRODED 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 ELCTRODES ARE ASSEMBLED INTO MULTICELL BATTERIES.

Abstract: A BATTERY PLAGUE IMPREGNATED WITH A METAL NITRATE IS HYDRATED BY BEING SUBMERGED IN A HOT, CONCENTRATED HYDROXIDE SOLUTION TO PRODUCE A METAL HYDROXIDE DEPOSIT IN THE PLAGUE AND A HYDROXIDE SOLUTION CONTASINING A NITRATE BYPRODUCT. THE HYDROXIDE SOLUTION CONTAINING THE NITRATE BYPRODUCT IS TRANSMITTED TO A CRYSTALLIZATION TANK WHERE UPON COOLING NITRATE CRYSTALS ARE FORMED AND RECOVERD. THE SOLUTION REMAINING AFTER CRYSTALLIZATION MAY BE RETURNED TO THE HYDRATION TANK. HYDROXIDE SOLUTION MAY BE ADDED TO MAINTAIN THE HYDROXIDE CONCENTRATION IN THE HYDRATION TANK AT A SUBSTANTIALLY UNIFORM LEVEL. BOTH BATCH AND CONTINUOUS PROCESSING MAY BE USED.

Abstract: A battery is provided with a passageway for the venting of gases generated by the cell. The passageway is outside of or in a gaspervious layer of the cell enclosure, and gases travel between the interior of the cell and the passageway by first passing through the gas-pervious layer. The passageway may be the center of a hollow, gas-pervious fiber. Alternatively, a fiber may be in a passageway between the unlaminated surfaces of an inner gaspervious layer and an outer layer which is impervious to liquids and less pervious than the inner layer to the gases generated by the cell. The gas-pervious layer may be (i) on the outside face of an end cell of the battery to provide a terminal vent, (ii) situated within a gas-pervious adhesive, or (iii) situated between the cells of a multicell battery.

Abstract: A CONTINUOUS STRIP OF SEPARATOR MATERIAL IS USED AS A CARRIER OF POSITIVE AND NEGATIVE ELECTRODES IN THE CONSTRUCTION OF MULTICELL BATTERIES. THE POSITIVE AND NEGATIVE ELECTRODES ARE FIRST PLACED ON OPPOSITE SIDES OF THE CONTINUOUS CARRIER STIP, AND SUBSEQUENTLY SEGMENTS OF THE CARRIER STRIP ARE ASSEMBLED INTO BATTERIES, EACH SEGMENT HAVING OPPOSED POSITIVE AND NEGATIVE ELECTRODES ON THE OPPOSITE SIDES THEREOF. PREFERABLY THE ASSEMBLY OF THE SEGMENT INTO BATTERIES OCCURS WHILE THE SEGMENTS ARE STRUCTURALLY CONNECTED TOGETHER AS UNDIVIDED PARTS OF THE CONTINUOUS CARRIER STRIP, BUT ALTERNATIVELY THE CARRIERSTRIP MAY BE CUT INTO STRUCTURALLY UNCONNECTED SEGMENTS BEFORE THE SEGMENTS ARE ASSEMBLED INTO BATTERIES.

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.
