Definitions

  • the present invention relates to a secondary battery such as a lithium secondary battery.
  • the secondary battery according to the first aspect of the present invention includes an electrode group for charging and discharging electricity, an opening, a can in which the electrode group is accommodated, and welded to the opening of the can, A lid for sealing the part, a positive electrode connecting member and a negative electrode connecting member, one end of which is electrically connected to the electrode group and the other end of which penetrates the lid and protrudes to the outside of the lid,
  • the positive electrode connecting member and the negative electrode connecting member are provided with a positive external terminal and a negative external terminal connected to the positive electrode connecting member and the negative electrode connecting member, respectively, by caulking, and the positive electrode connecting member and the negative electrode connecting member are spread outside the lid.
  • FIG. 1 is an exploded perspective view showing a winding group in a first embodiment of a secondary battery according to the present invention.
  • FIG. 6 is a longitudinal sectional view showing a first caulking step of the lid / terminal assembly of FIG. 5.
  • FIG. 7 is a longitudinal sectional view showing a second caulking step of the lid / terminal assembly of FIG. 6.
  • the electrode group 6 includes a positive electrode body 1 in which a positive electrode active material 2 is applied on both sides of a positive electrode metal foil, and a negative electrode body 3 in which a negative electrode active material 4 is applied on both sides of the negative electrode metal foil. 5 is wound around in a flat shape.
  • the positive electrode metal foil is made of, for example, aluminum having a thickness of 30 ⁇ m
  • the negative electrode metal foil is made of, for example, copper having a thickness of 15 ⁇ m.
  • the separator 5 is made of, for example, a porous polyethylene resin. Electric power is charged and discharged between the positive electrode active material 2 and the negative electrode active material 4 of the electrode group 6.
  • the lid / terminal assembly 200 includes a lid 11, positive and negative current collector plates 14 and 31, positive and negative electrode connection terminals 15 and 16, a gasket 10, an insulating member 12, and positive and negative electrodes. External terminals 13 and 32 are provided, and are integrated in a process described later.
  • the positive and negative current collector plates 14 and 31 are metal plates bent along the side surface shape of both end portions in the axial direction of the electrode group 6, and are made of aluminum and copper, which are the same as the material of the positive and negative electrode bodies 1 and 3.
  • the thin flat portion 15e15e Since the positive electrode connection terminal 15 on the positive electrode side is made of aluminum, the thin flat portion 15e15e has a high reflectance with respect to the laser beam. In order to increase the absorption rate of the laser beam, it is necessary to make the laser beam enter perpendicularly to the thin flat portion 15e15e, and it is desirable to minimize the inclination of the thin flat portion 15e and make the surface as flat as possible.
  • the range of the welded portion 30 is set to a narrower circumferential angle range and all the welded portions 30 are brought closer to the through hole 13b, the electric resistance is further reduced.
  • the bias of the caulking portion 17d is increased, which may be disadvantageous with respect to the caulking strength.
  • This embodiment has an effect that the manufacturing cost of the welding process can be reduced in addition to the effect of the first embodiment.
  • a third embodiment of the secondary battery according to the present invention will be described with reference to FIG.
  • the same or corresponding parts as those in the first and second embodiments are denoted by the same reference numerals, and differences will be mainly described.
  • the number of thin flat portions is one, which is a smaller number than in the first embodiment.
  • the electrode group has been described as a wound electrode group in which a long positive and negative electrode body is wound together with a separator, but the present invention can also be applied to a rectangular sheet-shaped laminated electrode group.
  • the secondary battery according to the present invention has been described as a secondary battery for driving a rotating electric machine of a hybrid vehicle or an electric vehicle, it can be used as a driving power source for various rotating electric machines of a railway vehicle or a construction machine. Or it can utilize also as a battery cell of the power supply device for electric power storage.
  • the present invention includes an electrode group housed in a battery can, a positive and negative external terminal that is exposed outside the battery can in order to connect the electrode group to an external load, an electrode group, and a positive and negative electrode
  • the present invention can be applied to various secondary batteries having positive and negative electrode connecting members that electrically connect external terminals. Therefore, the shape, structure, arrangement, and the like of the electrode group, the positive and negative external terminals, and the positive and negative electrode connecting members are not limited to the embodiments.
  • the positive and negative current collecting plates and the positive and negative electrode connecting terminals may be made from one material.
