  • Patent number: 7794868
    Abstract: A battery module is provided. The battery module includes a plurality of unit cells stacked proximate to one another. The plurality of unit cells define flow channels therebetween. Each unit cell of the plurality of unit cells is longitudinally positioned at a predetermined angle in a range between 3 and 14 degrees relative to a wall of an input port for a respective flow channel. The battery module further includes a cooling system that routes a coolant through the flow channels between the plurality of unit cells such that the coolant contacts the plurality of unit cells.

  • Publication number: 20090325043
    Abstract: Disclosed herein is a middle- or large-sized battery module comprising a plurality of stacked unit cells, each unit module including two or more plate-shaped battery cells electrically connected with each other, each battery cell having electrode terminals formed at opposite sides thereof. The battery module is manufactured by connecting electrode terminals of a pair of unit modules by welding, mounting a sensing unit, including a sensing member, to the welding part and bending the welding part such that the unit modules are stacked, and repeatedly performing the above processes until all the unit cells are stacked.

  • Patent number: 7288318
    Abstract: The present invention provides a hybrid material comprised of an active component for raw materials for cosmetics and a layered metal hydroxide, showing good stability, low toxicity, low irritation, good sustained release and good dispersibility. The present invention provides a method for preparing the hybrid material, using the coprecipitation method, the ion-exchange method or the adsorption method, depending on properties of the active component for raw materials for cosmetics. The method may further comprise a step of coating the surface of the hybrid material after preparation of the hybrid material. The present invention provides cosmectics comprising the above hybrid material.

  • Publication number: 20070126396
    Abstract: Disclosed herein is a battery module including a plurality of unit cells stacked one on another. The battery module has a cooling system that accomplishes contact type cooling by a coolant flowing through gaps (flow channels) defined between the unit cells, and the flow channels defined between the unit cells are at a predetermined angle to the flowing direction of the coolant at inlet ports of the flow channels. The contact rate of the coolant to the unit cells in the battery module is increased and a large number of turbulent flows are created by the changing the flow channel through which the coolant flows. Consequently, the occurrence of the velocity gradient of the coolant in the flow channel defined between the unit cells is prevented, and therefore, the cooling efficiency of the battery module is improved.
