Abstract
Disclosed herein is a secondary battery including an electrode assembly that can be charged and discharged, wherein the electrode assembly includes an electrode ('safety electrode') composed of a material that effects an electrochemical reaction when the secondary battery is overcharged (Overcharge reaction material'). The safety electrode according to the present invention is not directly added to components related to the operation of the secondary battery. Consequently, the safety electrode does not deteriorate the performance of the battery during the normal operation of the battery, and the safety electrode consumes the overcharge current through the electrochemical reaction, when the battery is overcharged, whereby the safety of the battery is fundamentally secured.
