摘要 |
A spirally coiled electrode assembly has positive and negative electrodes each including a web-like collector coated with an active material on opposite surfaces thereof, and separators disposed between the positive and negative electrodes. A plurality of rectangular leads extend from opposite sides of the web-like collectors in directions perpendicular to a direction in which the positive and negative electrodes and the separators are wound. Positive and negative terminals are connected to the rectangular leads extending from the respective opposite sides of the web-like collectors. The spirally coiled electrode assembly, the rectangular leads, and the positive and negative terminals are housed in a cylindrical casing whose opposite ends are closed by respective caps. The positive and negative terminals are fixed to the caps, respectively. <IMAGE> |
