WIPO Patent Application WO/2021/199488
Kind Code:
A1
Abstract:
This power supply device (100) is provided with: a cell stack (10) which is obtained by stacking a plurality of cells (1) each having an electrode terminal (2) on the upper surface of an outer package can; and a plurality of bus bars (40) each connecting electrode terminals (2) of cells (1) adjacent to each other. Each bus bar (40) is open at a window part (42) through which a part of an electrode terminal (2) of a cell (1) is visible in a state where the bus bar is overlapped with the electrode terminal (2) when viewed in plan. Consequently, even if a bus bar (40) is superposed on an electrode terminal (2), the electrode terminal (2) beneath the bus bar is visible through the window part (42) and the position or height of the connection can be seen, thereby enabling the enhancement of the connection reliability.
