Title:
ASSEMBLED BATTERY
Document Type and Number:
WIPO Patent Application WO/2013/001644
Kind Code:
A1
Abstract:
In the present invention, an assembled battery is provided with a plurality of battery cells with positive electrode terminals and negative electrode terminals made of different materials, and the plurality of battery cells are electrically connected to each other by a conductive plate. The positive electrode terminal of each battery cell is provided with a positive-electrode-side projection part, and the negative electrode terminal of each battery cell is provided with a negative-electrode-side projection part. The conductive plate comprises: a primary plate that bridges between the negative electrode terminal of one battery cell and the positive electrode terminals of other battery cells adjacent to that battery cell; and a secondary plate that is connected to the end section on the positive electrode side of the primary plate. The conductive plate is provided with a positive-electrode-side engagement part that engages with the positive-electrode-side projection part and a negative-electrode-side engagement part that engages with the negative-electrode-side projection part. The primary plate is a metal plate made of the same material as the negative electrode terminals, and one side of the primary plate is disposed to face the positive electrode terminals and the negative electrode terminals and is welded to the negative electrode terminal of one battery cell. The secondary plate comprises a metal plate made of the same material as the positive electrode terminals and is welded to the positive electrode terminal of another battery cell that neighbors the above one battery cell.
