Abstract
A can-type secondary battery is adapted to induce a short circuit between metal within the secondary battery when the secondary battery deforms due to an external impact in order to reduce heat generation and improve the safety of the secondary battery.
Claims16
A can-type secondary battery comprising:
- an electrode assembly having a first electrode plate, a second electrode plate and a separator;
- a can for containing the electrode assembly and an electrolyte;
- and
- a cap assembly having a cap plate, an insulation plate, an electrode terminal, and a terminal plate, the cap assembly being coupled to a top opening of the can to seal the top opening,
- wherein at least one side of the insulation plate having a terminal through-hole for electrode terminal passage is sized corresponding to the terminal plate mounted on a bottom surface of the insulation plate such that the terminal plate is contactable with an inner surface of the can upon can deformation due to longitudinal compression applied to the can-type secondary battery.

A cap assembly for a can-type secondary battery, the secondary battery including an electrolyte and electrode assembly having a first electrode plate, a second electrode plate and a separator, the cap assembly comprising:
- a cap plate;
- an electrode terminal insertable through the cap plate;
- and
- an insulation plate having a terminal through-hole for electrode terminal passage;
- wherein at least one side of the insulation plate is sized to correspond to a terminal plate mountable on a bottom surface of the insulation plate such that the terminal plate is contactable with an inner surface of the can upon can deformation due to longitudinal compression applied to the can-type battery.
