  • Seal for electrochemical cell
    Patent number: 6878486
    Abstract: The invention is an injection-molded thermoplastic seal member for use in an electrochemical cell and a cell containing the seal member. The thermoplastic material comprises a mixture of a polyolefin matrix, comprising more than 30 weight percent of the thermoplastic material, and an aromatic polymer having a repeating unit that comprises at least one aromatic functional group. The material has excellent molding properties and results in a seal member that forms a superior compressive seal in the electrochemical cell.

  • Electrochemical cell with low volume cover assembly
    Patent number: 6861174
    Abstract: An electrochemical battery cell comprising a metal container with an open end closed with a metal cover. The top portion of the container side wall has a torus above an inward necked area, and the cover has a flange shaped around the outside of the torus and extending into the necked area. The inside diameter of the cover flange is smaller than the outside diameter of the torus, so that the cover is locked onto the top of the can. The components sealing the top of the cell require a small volume so that the internal volume for active materials and electrolyte is large. The cell can be closed and sealed with little downward force on the can side wall below the neck, allowing use of a thinner can.

  • Electrochemical cell having venting current collector and seal assembly
    Patent number: 6855454
    Abstract: A low profile collector and seal assembly for sealing the open end of a container of an electrochemical cell and providing venting of pressurized gases. An electrochemical cell has a can with a closed bottom end and an open top end, positive and negative electrodes disposed in the can, and a collector and seal assembly disposed in the open top end of the can for closing the open top end of the can. The collector and seal assembly includes a current collector and an annular seal that move relative to each other from a sealed position to a vented position when the internal cell pressure reaches a pressure threshold to vent pressurized gases.

  • Method of prediction of in-vivo polymer performance by external experimentation
    Publication number: 20040215403
    Abstract: A method is disclosed of using external polymeric analytical techniques to predict in-vivo polymeric performance, more particularly, viscoelastic property characterization for performance modeling of biomedical devices that incorporate a polymeric component and are load-bearing during service. Time-Temperature Superposition can be used to accelerate external testing of pertinent properties. Boltzmann's superposition provides a mathematical methodology for determining the time-dependent strain that develops in response to an imposed stress history. The modeling of the present invention provides an opportunity to describe and predict behavior of the device during in-vivo service, as well as it providing a basis for evaluating alternate “candidate” polymers for use in the construction of the device.

  • Battery cell with improved pressure relief vent
    Publication number: 20040157115
    Abstract: An electrochemical cell with a pressure relief vent formed in a metal plate disposed in at least one of the closed end and the open end of the container. The pressure relief vent has an annular ring that includes a reduced thickness groove, interrupted in at least two places by unthinned sections of the plate. When the vent opens to relieve pressure from within the cell, the area of the plate within the annular ring remains attached to the remainder of the plate by at least one of the unthinned sections. A can with such a pressure relief vent formed in the can bottom is useful as an electrochemical cell container.

  • Increased volume electrochemical cell
    Patent number: 6759162
    Abstract: An electrochemical cell is provided having an anode cup, a gasket, and a cathode can.

  • Method and apparatus for managing congestion in a data communication network
    Publication number: 20030103451
    Abstract: A method for managing data congestion and/or contention occurring at a point-of-traffic concentration. The method includes reading a time value associated with a data packet, the time value being representative of when the data packet entered the network. The time value is within the header of the data packet. The age of the data packet is determined from the time value. The data packet is discarded if the age of the data packet is above a threshold value. Alternatively, a first time value determined from a time reference is associated with, a data packet at a first node. The data packet is transmitted to a second node and the first time value is compared to a second time value to provide a result. The second time value is also determined from the time reference. The data packet is discarded if the result exceeds a threshold value.

  • Electrochemical cell with improved gasket and seal
    Patent number: 6468691
    Abstract: Disclosed is an electrochemical cell using a gasket with projections on both surfaces of an upstanding wall. When used as a seal member between two parts of the housing of an electrochemical cell, a plurality of high compressive stress areas is formed in the gasket wall. When projections on opposite sides of the gasket are not horizontally aligned, an effective seal can be achieved with a thinner-wall gasket, providing more internal cell volume for active materials. Also disclosed is a process for assembling the cell.

  • Crimping die employing powered chuck
    Patent number: 6427302
    Abstract: A forming die includes a base and at least two die segments. At least a first one of the die segments is moveably mounted to the base for shifting between closed and opened positions. The die segments together define a cavity having an opening when the first die segment is in the closed position. A punch is moveably mounted to the base for shifting between a retracted position and an extended position wherein the punch crimps a part positioned within the cavity. A powered actuator is connected to at least the first one of the die segments, and shifts the first die segment between the closed and opened positions such that a part positioned within the cavity can be removed after crimping by shifting of the first die segment to the open position. The forming die is particularly well-suited for crimping electrochemical cells.
