Title:
ELECTRIC DEVICE MODULE AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2007/032273
Kind Code:
A1
Abstract:
A method or the like of producing a cell module capable of downsizing the entire
cell module in a constitution in which electrode tabs led out from cells are joined
by welding. The cell module (50) has cells (20) having sheet-form electrode tabs
(25a, 25b) led out from film packages, and cases housing the cells therein. The
method of producing the cell module (50) comprises the step of disposing each
cell (20) in each case to partially allow electrode tabs (25a, 25b) to overlap
each other, and the step of welding electrode tabs to each other while cooling
the electrode tabs by supplying cool air to the electrode tabs.
