  • Patent number: 10381608
    Abstract: A flat type battery includes an exterior member housing an electrolytic solution and a power generating element. The power generating element contains electrodes alternating layered between electrolyte layers, and expands with use in a layering direction of the electrodes. The exterior member forms a tightly sealed space in which the power generating element is housed, and in which an extra space is formed between the exterior member and a side surface extending along the layering direction of the power generating element. The exterior member includes a volume adjustment portion allowing for an increase in the volume of the extra space by expanding in response to a pressure rise inside the tightly sealed space while the exterior member is being pressed against the surfaces intersecting the layering direction of the power generating element due to a pressure difference between the exterior and the interior.

  • Patent number: 10326126
    Abstract: Provided are a negative electrode active material and a method of preparing the same, and particularly, the present invention relates to a negative electrode active material including a core including natural graphite, and a shell surrounding the core and including a roughened amorphous carbon layer. Since the negative electrode active material according to the present invention has a roughened surface, adhesion may be improved by using a less amount of a binder due to an anchoring effect in which curved surfaces of active material particles in contact with each other are anchored. Thus, an increase in resistance due to the use of an excessive amount of the binder may be prevented while achieving high loading in a negative electrode. Also, since a specific surface area is increased due to the roughened surface, access of lithium ions becomes easy, and thus, high output of a battery may be obtained.

  • Patent number: 9629270
    Abstract: A vehicle data recording unit for installation in a motor vehicle having a housing. Within the housing is an electronic memory and control unit and a battery receptacle for receiving a buffer battery for the memory and control unit. The battery receptacle has a battery compartment delimited by a first stop and a second stop, situated opposite the first stop, for holding a first buffer battery between the first stop and the second stop. To make it easy to use buffer batteries of different physical sizes, a third stop is arranged between the first stop and the second stop, which has a smaller length than the first buffer battery, in the battery compartment between the third stop and the first stop, such that optionally the first buffer battery or the second buffer battery can be held in the battery compartment.

  • Patent number: 9614246
    Abstract: The invention discloses a high-capacity cylindrical lithium ion battery. Tab-position end face is shaped; a high frequency oscillation and pressure are applied on to make the foil bodies softened in the scope of 0.1-6.5 mm. At the instant of high-frequency oscillation, the rigidity of the foil body is greatly decreased; and the foil bodies are mutually wound and compressed together, so that the weight density of the foil body in unit volume is increased and meanwhile, the rigidity of the compressed foil body at the Tab-position end face is greatly increased, thereby laying a firm foundation for laser welding of the 1 Tab-position end face and a current collector, increasing a laser welding effective area of the Tab-position end face and the current collector, and improving the welding strength.
