Title:
電極リード及びそれを含む二次電池
Document Type and Number:
Japanese Patent JP5881228
Kind Code:
B2
Abstract:
An electrode lead is applied as a part of at least one of a cathode lead and an anode lead of a secondary battery and includes a first metal plate and a second metal plate spaced apart from each other with a gap therebetween and having coating layers formed on the surfaces thereof except for surfaces of end portions thereof facing each others, and a metal bridge made of material having a lower melting point than the first metal plate and the second metal plate and buried in the gap so that the end portions are not exposed. In this case, if an overcurrent flows through the electrode lead, a portion of the metal plate at which a metal bridge is formed is rapidly broken to irreversibly interrupt the overcurrent flowing at the secondary battery without giving a substantial influence on the temperature of the secondary battery.
