<p>PROBLEM TO BE SOLVED: To provide a storage battery of high discharge capacity by means of an electricity collection part with a large cross section and short length for welding the sealing member and collector. SOLUTION: A storage battery comprises a battery case 16 with an opening serving as one of the positive and negative electrodes terminal, sealing member 17 serving as the other electrode terminal for sealing the opening of the case, electrode assembly 10 made of positive and negative electrode plates 11 and 12 mounted in the case 16 with the collector 14 connected to at least one end the positive and negative electrodes 11 and 12. The sealing member 17 and the collector 14 are connected with a lead member consisting of a drum-like part 20 with the central part of the periphery being concave. The upper and lower ends of drum-like part are provided with blades 22 and 23 having large width part 22a, 23a and small width parts 22b, and 23b alternately arranged, so that the large width part 22a faces the small width part 23b with a gap between them, and the small width part 22b faces the large width part 23a with a gap.</p> |
