Kupplung zwischen Stromkollektor und Endpol für primäre oder sekundäre Lithiumbatterie |
摘要 |
A rod-shaped coupler (72) for connecting a current collector (70) to a terminal pin (88), is described. The coupler is secured to the entire width of the current collector, preferably the cathode (64) in a cell of a case negative design, and is generally aligned along the longitudinal axis of the electrode assembly. An extension portion (82) of the coupler extends beyond the electrode assembly and is of a hollow, tubular structure crimped or otherwise collapsed into surrounding contact with the terminal pin. The coupler (72) and terminal pin (88) are then welded (94) together. Preferably, the terminal pin is roughened prior to effecting the connection. This method of attachment is suitable for either primary lithium or secondary lithium ion cells, particularly those powering implantable biomedical devices. <IMAGE> |
