| 摘要 |
The invention provides a metal-air button cell (10) that provides improved leak-proof properties without requiring a significant expense in manufacturing costs. The cell (10) is composed of a cathode can (12), a saucer-shaped cover (14) which is electrically insulated from the can by a grommet (16) that extends over the outer sides and the rim of the cover. A cathode assembly (24) is located in the cathode can (12) and extends to the walls (18) thereof. A resilient washer (44) is placed between the cathode assembly (24) and that part of the grommet (16) that covers the rim of the cover (14). Anode material (40) is provided together with a separator (36) to prevent shorting between anode and cathode material. The cell (10) is sealed by crimping the top edge of the can (12) against the grommet (16) which compresses the cathode between the can and the washer (44). |
