Abstract
A burr of a busbar is prevented from interfering with the electrodes of a battery cell. A busbar includes: a flat plate portion having a back surface that is to be fixed to electrodes of a battery cell through welding, wherein a burr at an outer peripheral edge of the flat plate portion protrudes only toward a surface of the flat plate portion. A busbar coupled body A includes: a plurality of plate-shaped busbars that are disposed aligned at an interval; and a coupling portion that couples opposing edge portions of the adjacent busbars to each other, wherein a boundary between the coupling portion and each of the opposing edge portions is separated through pressing.
Claims6
A busbar comprising:
- a flat plate portion having a back surface configured to be fixed to electrodes of a battery cell through welding,
- wherein a burr at an outer peripheral edge of the flat plate portion protrudes only toward a surface of the flat plate portion opposite to the back surface.
A busbar coupled body comprising:
- a plurality of plate-shaped busbars configured to be fixed to electrodes of a battery cell through welding, and that are disposed aligned at an interval;
- and
- a coupling portion that couples opposing edge portions of the adjacent busbars to each other,
- wherein a boundary between the coupling portion and each of the opposing edge portions is configured to be separated through pressing.
