摘要： A fixture in which an attractive magnetic force is utilized to join two parts of a container or housing together is discussed. The fixture comprises a fixture body portion, a fixture base portion and a removable fixture plate portion. At least one body magnet resides within the fixture body portion and at least one plate magnet resides within the removable fixture plate. The fixture body and plate magnets are positioned such that when they are brought together, an attractive magnetic force pulls the plate towards the fixture body. Therefore, when the respective housing portions are positioned within the fixture, the magnetic force compresses the housing portions together.

摘要： An electrochemical cell comprising a conductive casing housing an electrode assembly provided with a stack holder surrounding the electrode assembly is described. The stack holder is of a shape memory material that serves to maintain the anode and cathode in a face-to-face close physical proximity alignment throughout discharge. This is particularly important in later stages of cell life. As the cell discharges, anode active material is physically moved from the anode to intercalate with the cathode active material. As this mass transfer occurs, the cathode becomes physically larger and the anode smaller. This can lead to gaps forming between the anode and the cathode. However, the stack holder inhibits the formation of such gaps by maintaining a compressive force on the electrode assembly throughout cell discharge.
