  • Publication number: 20180219209
    Abstract: The present invention relates to an electrochemical storage battery (A) containing lithium, comprising an electrochemical bundle (F), two current collectors, one of which is connected to the bundle anode and the other to the bundle cathode, and a housing (6) elongated along a central axis (X) and having a lid (9), a bottom (8) and a side casing (7) joined to both the bottom and the lid, the housing being designed to receive the bundle in a sealed manner, and some of the current collectors forming the poles (40, 50) extending through the housing. According to the invention, a circuit-breaker device is provided, which has a housing bottom wall that deforms in the plastic deformation range, as well as a rated breaking line provided around the central portion of the collector, which can tear in order to electrically separate said central portion, connected to the bottom, from the main external surface of the current collector, which is connected to one end of the electrochemical bundle.

  • Patent number: 9859546
    Abstract: A method for producing an electrochemical bundle of a lithium battery, such as an Li-ion battery, with a view to electrically connecting same to the output terminals of the battery, wherein it includes the combination of two steps of folding an electrochemical bundle of a lithium battery which are carried out separately, i.e. a radial folding with plastic deformation and an axial compacting, which make it possible to obtain two separate areas on at least one, and preferably both, of the lateral ends of the bundle. The invention also concerns a method for producing an electrical connection part between the electrochemical bundle and one of the output terminals of the battery, and an associated current collector.
