Abstract
Disclosed is an electrochemical device including a gas discharge member disposed in inner volumes thereof or used as an element for forming the device, wherein the gas discharge member comprises: (a) a core portion containing a compound that discharges gases other than oxygen at a predetermined temperature range; and (b) a polymeric shell portion for encapsulating the compound and surrounding the core portion. A center pin for an electrochemical device having the gas discharge member inserted into the interstitial volumes of the device is also disclosed. The electrochemical device comprising the gas discharge member, which discharges a large amount of gas at a predetermined temperature and is inserted into the inner volumes of the device, is prevented from ignition or explosion under overcharge and high-temperature storage conditions with no drop in the performance.
