BATTERY HAVING CELL TAB CONNECTING STRUCTURE WITH RESISTANCE WELDING

摘要

PURPOSE: A battery having a cell tab connecting structure is provided to improve contact stability, and to reduce the number of components because of relatively simple structure. CONSTITUTION: A battery(100) having a cell tab connecting structure by resistance weld comprises a plurality of many cells having a pair of tabs consisting of a negative electrode tab(111a) and a positive electrode tab(111b). The tabs have plate-shape. The tabs are projected to face of the plate sides of the negative electrode tab and the positive electrode tab each other along one side of the cell. A supporting member(120) for fix-supporting the location of the cell is inserted between the cells.
