Connection for joining a current collector to a terminal pin for a primary lithium or secondary lithium ion electrochemical cell |
摘要 |
A rod-shaped coupler for connecting a current collector to a terminal pin, is described. The coupler is secured to the entire width of the current collector, preferably the cathode in a cell of a case negative design, and is generally aligned along the longitudinal axis of the electrode assembly. An extension portion 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 and terminal pin are then welded 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.
