“Secondary Battery With A Deformation Inducing Groove”
Abstract: A secondary battery includes a first electrode plate and a second electrode plate, a case accommodating the electrode plates, and a cap assembly to seal the case. The cap assembly has a short-circuit hole and a cap plate electrically connected to the first electrode plate. The battery also includes an inversion plate spaced from a short-circuit plate. The inversion plate is positioned in or over the short-circuit hole and bent toward the case. The short-circuit plate is electrically connected to the second electrode plate. When an internal pressure of the battery exceeds a value, the inversion plate moves to contact the short-circuit plate, which, in turn, breaks a fuse. A groove is included in the gap assembly adjacent the short-circuit plate. When the inversion plate moves under excessive pressure, an edge portion of the gap assembly deforms away from the short-circuit plate.
