Rechargeable battery
The present invention discloses a rechargeable battery that has an improved mounting structure for an electrode terminal and a second protective device used therein. This improved structure improves the function of the rechargeable battery. The rechargeable battery comprises an electrode assembly that has first electrode plate, a second electrode plate, and a separator for insulating the electrode plates from each other, all of which are wound together. It also includes a can that contains the electrode assembly therein, a cap assembly that has a cap plate for sealing a top opening of the can, an electrode terminal that is insulated and inserted into a terminal through-hole formed on the cap plate, and a terminal groove formed on the top of the terminal through-hole with a shape corresponding to that of the head of the electrode terminal so that the head of the electrode terminal can be housed therein. The rechargeable battery of the present invention also includes a protective device groove spaced at a predetermined distance from the terminal groove and a second protective device housed in the protective device groove with one end connected to the top surface of the electrode terminal.
