PRODUCTION METHOD FOR ELECTRIC DEVICE ASSEMBLY AND ELECTRIC DEVICE ASSEMBLY

摘要

Battery cells (20) each having sheet-form electrode tabs (25a, 25b) led out from the opposite ends are connected to each other in the following manner. First, battery cells (20) are flatly arranged in one row so that the electrode tab (25a) of one battery cell (20) and the electrode tab (25b) of the other battery cell (20) partially overlap each other. Next, the electrode tabs are connected with each other at the overlapped portions (35A, 35B) where the electrode tabs overlap. Then a plurality of battery cells (20) are laminated one upon another in a staggeringly folded up form.
