Abstract
The present invention provides a secondary battery including an insulating plate which enables easy gas discharge and is not broken at high temperature. For this purpose, disclosed is a secondary battery comprising: a case including a space therein through an opening; at least one electrode assembly inserted into the space of the case; an insulating plate formed at an upper part of the electrode assembly; and a cap plate which is coupled to the opening of the case and includes a vent, at least one region of which has a thinner thickness than other regions, wherein the insulating plate includes a plurality of gas discharge holes disposed at a region corresponding to the vent.

A secondary battery comprising:
- a case including a space therein through an opening;
- at least one electrode assembly inserted into the space of the case;
- an insulating plate formed at an upper part of the at least one electrode assembly;
- and
- a cap plate which is coupled to the opening of the case and includes a vent, at least one region of which has a smaller thickness than other regions,
- wherein the insulating plate includes a plurality of gas discharge holes disposed at a region corresponding to the vent, the plurality of gas discharge holes are partitioned by at least one partition to be separated from each other, the at least one partition defines an upper surface of the insulating plate at the region corresponding to the vent, and the gas discharge holes extend to the upper surface and pass therethrough.
