  • Patent number: 9768428
    Abstract: The invention relates mainly to a system of electrochemical cells for the production of a battery module for an electric or hybrid vehicle, comprising a stack of flexible electrochemical cells, characterized in that it comprises at least one support strip with at least one electrochemical cell disposed on the surface thereof. According to the invention, the support strip can be cut such that the number of electrochemical cells disposed on the surface is adapted to provide the necessary battery power, and the strip can be folded such as to allow the electrochemical cells to be positioned side by side and stacked on top of one another.

  • Patent number: 8920960
    Abstract: The present invention provides a lithium secondary battery using a separator including a porous film formed by binding inorganic oxide particles together with a binder. The inorganic oxide particles are treated so that an amount of alkali metal elements eluted therefrom when they are immersed in ion exchange water is reduced to 1000 ppm or less. As a result, it is possible to provide a lithium secondary battery with a high degree of reliability, whose characteristics deteriorate less when it is used or stored for an extended period.

  • Patent number: 8877367
    Abstract: In an All-Electron Battery (AEB), inclusions embedded in an active region between two electrodes of a capacitor provide enhanced energy storage. Electrons can tunnel to/from and/or between the inclusions, thereby increasing the charge storage density relative to a conventional capacitor. One or more barrier layers is present in an AEB to block DC current flow through the device. The AEB effect can be enhanced by using multi-layer active regions having inclusion layers with the inclusions separated by spacer layers that don't have the inclusions. The use of cylindrical geometry or wrap around electrodes and/or barrier layers in a planar geometry can enhance the basic AEB effect. Other physical effects that can be employed in connection with the AEB effect are excited state energy storage, and formation of a Bose-Einstein condensate (BEC).

  • Patent number: 8647763
    Abstract: A battery coolant jacket for use with a plurality of cells is provided, the jacket comprised of a hollow enclosure configured to permit a liquid coolant to flow through the enclosure, entering via a coolant inlet and exiting via a coolant outlet; a plurality of cell apertures that extend completely through the hollow enclosure, where each cell aperture is sized to fit a cell; and a plurality of coolant segregation walls that are integrated into the hollow enclosure and separate the cells into groups of cells, and where each coolant segregation wall forms a barrier between the cell group contained within that coolant segregation wall and the liquid coolant flowing through the hollow enclosure. The coolant jacket may include at least one flow control wall integrated within the hollow enclosure that controls the coolant flow pathway between the enclosure's coolant inlet and outlet, for example causing the coolant flow pathway to alternate directions between adjacent cell groups.

  • Patent number: 7638222
    Abstract: The porous, gas permeable layer substructure (5; 5a, 5b) for a thin, gas tight layer (89) can in particular be used as a functional component in high temperature fuel cells (8). This layer substructure has a smooth surface (50a) which is suitable for an application of the gas tight layer or a multi-layer system including the gas tight layer, with the application being carried out by means of a screen printing method or other coating methods. The smooth surface is formed by a compacted edge zone (50). The edge zone and a carrier structure (51) adjacent to this are made from sinterable particles of a uniform substance mixture. The porosity of the carrier structure is greater than 30 volume percent, preferably greater than 40 volume percent. The pore size of the edge zone is smaller than 10 ?m, preferably smaller than 3 ?m.
