  • Patent number: 8785020
    Abstract: Disclosed is an anode for a lithium secondary battery. The anode includes a current collector in the form of a wire and a porous anode active material layer coated to surround the surface of the current collector. The three-dimensional porous structure of the active material layer increases the surface area of the anode. Accordingly, the mobility of lithium ions through the anode is improved, achieving superior battery performance. In addition, the porous structure allows the anode to relieve internal stress and pressure, such as swelling, occurring during charge and discharge of a battery, ensuring high stability of the battery while preventing deformation of the battery. These advantages make the anode suitable for use in a cable-type secondary battery. Further disclosed is a lithium secondary battery including the anode.

  • Patent number: 8652675
    Abstract: The present invention relates to a cooling structure of a lithium ion secondary battery system. The cooling structure of a lithium ion secondary battery system according to the present invention provides cooling channels for lithium battery unit cells accommodated by a laterally partitioned arrangement of main frames, each having a heat radiation part and lattice-shaped paths, and partitioning frames, and allows air, blown by a cooling fan, to cool the lithium battery unit cells while passing through the cooling channels and the lattice-shaped paths. Each of the main frames has a pair of passage slots formed in both sides thereof to allow the air blown by the cooling fan to be directly blown to each accommodated lithium battery unit cell, thus forming each secondary cooling channel communicating with the pair of passage slots.

  • Patent number: 8642204
    Abstract: A high-reliability battery pack is described. A battery pack has a battery module unit that is formed from a plurality of arranged battery modules, each of which has a plurality of cells in a case, a cooling air flow passage where a cooling air flow flows, and a gas exhaust duct which forms a gas exhaust passage. The gas exhaust duct extends in an arrangement direction S of the plurality of the battery modules while being contiguous to the battery module unit, and takes in the gas released in the case from the cell, then exhausts the gas from the battery module. The gas exhaust duct is provided with a gas inlet for taking in the gas, which communicates with a gas emission hole formed on a surface of the case, and an air intake that serves to take in the cooling air flow.
