摘要： A current interrupt assembly for electrochemical cells is disclosed. The current interrupter assembly may be a self-contained, sealed unit which may be separately inserted into the cell during cell construction. Several current interrupt assemblies may be inserted in the cell. The current interrupter assembly has particular utility for thin rechargeable cells and when inserted in the cell forms a portion of the electrical pathway between a cell electrode and corresponding terminal. The current interrupt mechanism comprises a thin thermally responsive member preferably comprising a disk of a shape memory metal alloy having a curved surface. The current interrupt mechanism may include a heat producing electrical resistance means, preferably a Zener diode in proximity to the thermally responsive member. When cell temperature exceeds a predetermined value the disk deflects to cause a break in the electrical pathway within the assembly. The assembly may include therein a flexible electrically conductive member which forms a part of the electrical pathway within the assembly and which is physically responsive to deflection of the thermally responsive member. The assembly may also include a pressure actuated diaphragm which may form a portion of the assembly housing. When the cell internal pressure exceeds a predetermined level the diaphragm deflects causing a break in the electrical pathway within the assembly, thereby shutting down the cell.

摘要： A current interrupt mechanism for electrochemical cells is disclosed. A thermally activated current interrupt mechanism is integrated into an end cap assembly for an electrochemical cell. The thermally responsive mechanism preferably includes a free floating bimetallic disk which deforms when exposed to elevated temperature causing a break in an electrical pathway within the end cap assembly. This prevents current from flowing through the cell and effectively shuts down an operating cell. Alternatively, the thermally responsive mechanism may include a meltable mass of material which melts when exposed to elevated temperature to break an electrical pathway within the end cap assembly. The end cap assembly may also include integrated therein a pressure responsive current interrupt mechanism. If the internal gas pressure within an operating cell exceeds a predetermined value, the pressure responsive mechanism activates to sever an electrical pathway within the end cap assembly to prevent current from passing through the cell. The pressure responsive mechanism may include a diaphragm which ruptures when there is extreme gas pressure buildup. Gas is allowed to escape from the cell interior to the external environment through a series of vent apertures within the end cap assembly.

摘要： A thin, integrated carbon/insulator structure, and a method for fabricating same, for use in a primary electrochemical cell. A quantity of a wet carbon slurry material including a mixture of carbon black, water and/or isopropyl alcohol, and a binder such as finely-divided "Teflon" in suspension, is deposited onto a porous fiberglass substrate and rolled to a prescribed thickness. The rolling operation causes a portion of the slurry material to diffuse into the surface of the porous fiberglass substrate and permanently adhere to and unite with a surface portion of the fiberglass substrate in an integrated, interlocking fashion. The fiberglass substrate having the layer of carbon slurry material integrated therewith is then dried to cause the layer of carbon slurry material to dry and shrink to the form of a layer of carbon plaque having a network of cracks produced therethrough in a random pattern as a result of the shrinkage during drying. The layer of carbon plaque at this stage represents an aggregation of porous carbon globules. The layer of carbon plaque is re-rolled to close cracks at the upper surface of the layer while simultaneously establishing a desired thickness for the layer. After curing the above arrangement to increase adherence of the carbon globules to each other and to the fiberglass substrate, an integrated carbon/insulator structure of a desired size and configuration for use in a primary electrochemical cell can be cut out from the abovedescribed arrangement.

摘要： An electrochemical cell having an on-cell tester for visually indicating the condition of the cell is provided with an electrically conductive metal ring pressed onto the negative terminal at the crimp seal end of the cell, to permit the tester lead to make an electrical contact with the negative terminal without shorting across the positive terminal of the cell. The ring has a cylindrical wall portion or gripping means which frictionally grips a corresponding mating cylindrical wall potion on the negative terminal and also has a flange portion adjacent the positive terminal. A layer of electrically insulating material disposed between the flange and positive terminal prevents electrical contact between the terminals. The tester lead is either permanently electrically connected to the ring or intermittently connected by the user, depending on the type of tester used.

摘要： A high discharge rate electrochemical battery structure is disclosed as having a perforated disc electrode stack comprising pluralities of disc electrodes respectively connected to a pair of busbars. Each disc electrode has a tab with two fins which are bent at 90 degrees to the disc electrode. Each fin is inserted between two parts of the corresponding busbar and welded thereto.

摘要： A metal current collector substrate adapted to be inserted into an elongated cylindrical housing of a primary electrochemical cell. The metal current collector substrate is employed together with porous carbon and fiberglass separator elements to form a carbon current collector electrode/separator assembly for use in the electrochemical cell.The metal current collector substrate in accordance with the invention comprises a thin, circular, metal disc (e.g., of nickel) having a plurality of curved notches around its periphery. The notches are equally-spaced about the periphery of the disc (e.g., at 45.degree. intervals) and define a plurality of deflective, resilient arcuate portions intermediate to the notches. Prior to insertion into the housing of the cell, the disc is flat and has a diameter greater than the internal diameter of the housing. The disc is inserted into the housing by pushing the disc longitudinally into the housing whereupon the arcuate portions are deflected upwardly by physical contact with the interior wall of the housing. This deflection causes the arcuate portions to move toward each other and in turn to cause the disc to generally conform to the interior cross section of the housing. The arcuate portions following the deflection thereof are at acute angles with respect to the interior wall of the housing and make direct physical contact with the wall of the housing. In addition, due to the adjacency of the notches in the disc to the wall of the housing, a plurality of passageways are established between the disc and the interior wall of the housing.
