    摘要： A zinc/air button cell having an adhesive sealant applied to a portion of the inside surface of the cell's cathode casing. The adhesive sealant can be applied to the inside surface of a recessed annular step surrounding the cell's positive terminal on the cathode casing. The adhesive is preferably applied in a pattern which conforms to the shape of the annular recessed step. An electrolyte barrier sheet, preferably of Teflon, can be applied to the adhesive pattern on the inside surface of said recessed step, preferably so that the adhesive bonds the edge of the barrier sheet to the step. The adhesive prevents electrolyte from leaking from the cell. The adhesive is applied preferably by preparing a plate having a desired pattern etched thereon, filling the etching in the plate with an adhesive mixture, applying a silicon pad to the etching to transfer the adhesive pattern to the pad, then applying the pad to the inside surface of the cathode casing step to transfer the adhesive pattern thereto. The adhesive is preferably a solvent based mixture comprising a polyamide.

    摘要： A primary lithium cell having a wound electrode assembly. The electrode assembly comprises an anode comprising lithium, a cathode comprising a manganese dioxide and an electrolyte permeable separator therebetween. The electrode assembly comprises a cathode sheet, an anode sheet and electrolyte permeable separator sheet therebetween. The sheets are wound into a spiral roll. An exposed edge of each revolution of the separator sheet is then heat treated, for example, by applying a heated platen thereto to mold said exposed edge into a continuous separator membrane. The continuous separator membrane, so formed, covers and seals off said edge of adjacent revolutions of the cathode sheet and thus provides electrical insulation therefor. The electrode assembly can then be inserted into the cell casing so that the continuous separator membrane abuts a surface of the casing and provides electrical insulation between the casing and the wound cathode sheet. This reduces the total amount of electrical insulation needed between the cell casing and wound electrodes and thereby frees up void volume which can be used for additional active material, for example, by making the anode and cathode sheets wider.

    摘要： A high-rate, low-temperature, primary electrochemical cell. The cell in accordance with the invention includes an elongated cylindrical metal housing within which a vertical array of battery stack components is disposed and exposed to a cathodelectrolyte solution. Each of the battery stack components has an opening therein through which an elongated metal rod located centrally within the housing passes and serves as an electrical terminal for the cell.The components of the battery stack include a plurality of thin, flat, circular, lithium anode discs secured to the metal rod, and a plurality of carbon current collector cathode/insulator structures arranged in the array in alternation with the lithium anode discs. Each of the carbon current collector cathode/insulator structures includes a generally circular, thin, metal current collector spaced from the metal rod by way of the opening therein and having a size and shape so as to generally conform to the interior configuration of the housing and make direct physical contact with an interior wall of the housing. First and second circular, flat, thin, porous carbon layers are disposed on opposite sides of the metal current collector and spaced from the metal rod by way of the openings therein. First and second circular, flat, porous fiberglass insulators integrated with the first and second porous carbon layers, respectively, are in direct physical contact with adjacent ones of the lithium anode discs and separate the porous carbon layers from the adjacent lithium anode discs.

    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. 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： An electrochemical cell is disclosed, having a sealed prismatic housing with two opposing, internal side surfaces defining therebetween an internal cavity having width and length. One of the side surfaces defines a convex arc, and the other of the side surfaces has a center portion opposing the convex arc of the one side surface, and features extending toward the one side surface and straddling the convex arc. An electrode stack is contained within the internal cavity of the housing, having positive and negative electrode sheets arranged in face-to-face relation. The electrode stack is arranged between the side surfaces of the housing such that the stack is retained between the one side surface and the extending features of the other side surface, and deflected to follow the convex arc to maintain contact pressure between the positive and negative electrode sheets. The stack is thus stretched across an inwardly crowned surface of the housing. The invention can, by maintaining good intersheet contact pressure within the stack, provide good overall active material utilization (for high cell capacity) and can help to inhibit housing distension of cells with broad sides. Methods of construction are also disclosed.
