According to an embodiment of the present invention, a rechargeable battery comprises: an electrode assembly; a case in which the electrode assembly is accommodated; a cap plate coupled to an openingof the case to seal the inside of the case and having a plurality of vent portions; a lifting member installed through the cap plate and moved by the internal pressure of the case; and a plurality ofvent plates for sealing the vent portions, respectively, wherein the vent plates are connected to the lifting member through a connection member and interlocked with the lifting member.

Description

Technical field [0001] The present disclosure relates to a rechargeable battery for simultaneously opening a plurality of ventilation units and quickly discharging internal gases. Background technique [0002] Unlike a battery that cannot be charged, rechargeable batteries can be repeated and discharged. Rechargeable batteries are used in portable small electronic devices such as smartphones, laptops, and cameras, or as a motor driven by a motor for hybrid vehicles. [0003] Rechargeable batteries include an electrode assembly including a positive electrode, a negative electrode, and a partition located between the positive electrode and the negative electrode. The electrode assembly is received in the housing to perform charging and discharge, and the electrode terminal is supplied to the housing to supply or receive current. The housing can have a square shape or may be a bag type. [0004] The ventilation unit can be supplied to the housing of the rechargeable battery. With re...
