ASSEMBLED BATTERY, EXTERIOR TUBE EQUIPPED BATTERY, AND MANUFACTURING METHOD OF ASSEMBLED BATTERY WELDED TO BUS BAR

摘要

An assembled battery includes: a holder having a holding hole; and an exterior tube equipped battery, wherein: the holder accommodates the exterior tube equipped battery into the holding hole; the exterior tube includes a cylindrical outer-peripheral-surface adhesion portion and a toric peripheral edge covering portion that covers a surface peripheral edge portion; and;the assembled battery includes a first adhesive injected and solidified in a gap between an outer peripheral surface of that part of the exterior tube equipped battery which is placed inside the holding hole and that inner peripheral surface of the holder which constitutes a hole wall of the holding hole, and a second adhesive injected and solidified in a gap between the surface peripheral edge portion of the battery and the peripheral edge covering portion.

主权项

1. An assembled battery comprising:
a holder including a front surface, a back surface, and a holding hole, the holding hole being a cylindrical hole penetrating through between the front surface and the back surface; and an exterior tube equipped battery including
a cylindrical battery extending in an axis direction, the cylindrical battery including
a first surface placed on one end side in terms of the axis direction,a second surface placed on the other end side in terms of the axis direction, andan outer peripheral surface placed between the first surface and the second surface, anda cylindrical exterior tube including an electrical insulation property and covering the outer peripheral surface of the battery, wherein: the exterior tube equipped battery has an outside diameter smaller than an inside diameter of the holding hole; the holder accommodates the exterior tube equipped battery into the holding hole; the exterior tube includes
a cylindrical outer-peripheral-surface adhesion portion tightly adhered to the outer peripheral surface of the battery, anda toric peripheral edge covering portion that covers a surface peripheral edge portion, which is an outer peripheral edge portion of at least either one of the first surface and the second surface of the battery;the assembled battery includesa first adhesive injected and solidified in a gap between an outer peripheral surface of that part of the exterior tube equipped battery which is placed inside the holding hole and that inner peripheral surface of the holder which constitutes a hole wall of the holding hole, anda second adhesive injected and solidified in a gap between the surface peripheral edge portion of the battery and the peripheral edge covering portion.
