  • Patent number: 8580439
    Abstract: 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.

  • Patent number: 8216715
    Abstract: A prismatic battery is provided with a fixing portion composed of projections 29Aa and 29Ba for fixing the position of a flat electrode assembly 11 and a battery outer can 12 by contacting with an insulating sheet 32 on at least one of a positive electrode collector member 16 and a negative electrode collector member 18. The insulating sheet 32 is provided between the projections 29Aa, 29Ba and the battery outer can 12. Tips 29Ab and 29Bb of the projections 29Aa and 29Ba project from the flat electrode assembly 11 towards the battery outer can 12 side. The height of the projections is smaller than the thickness of the insulating sheet 32. This prevents short-circuiting between the positive electrode collector member or the negative electrode collector member, and the battery outer can. Thus, a prismatic battery suitable for EVs and HEVs with excellent safety can be obtained.

  • Patent number: 8119282
    Abstract: The invention relates to a cell connector (6) for a battery, especially for absorbing, in conjunction with at least one damping element (9), the vertical forces that are caused by the impact of shocks. The cell connector (6), at one end, is connected to the positive or negative electrodes (4, 5) which are received in a housing (2) having a housing cover (3), and, at the other end, comprises at least one terminal (7, 8) projecting from the housing cover (3). The aim of the invention is to elastically dampen the electrode plates (4, 5) of an accumulator (1) which are disposed inside a housing (2). For this purpose, a terminal (6) having a supporting shoulder (11), integrally molded thereto, is used in the housing (2), a damping element (9), disposed between the housing cover (3) of an accumulator (1) and the cell connector (6), coming to rest thereon.
