Abstract

A secondary battery according to the present invention comprises: a battery case having an electrode assembly and an accommodation unit for accommodating an electrolyte; a fluid inlet / outlet port formed at the battery case and having a moving path, through which a fluid can move, so as to enable discharge of an inner gas and re-injection of the electrolyte; a gas discharge unit for restricting thedischarge of the internal gas which passes through the fluid inlet / outlet port; and an electrolyte re-injection unit provided so as to enable the re-injection of the electrolyte through the fluid inlet / outlet port.

Description

technical field [0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims the benefit of priority of Korean Patent Application No. 10-2017-0084895 filed on July 4, 2017, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to a secondary battery. Background technique [0004] Unlike primary batteries, secondary batteries are rechargeable, and in addition, the possibility of miniaturization and high capacity is high. Thus, many studies on secondary batteries are recently being conducted. With technological development and increased demand for mobile devices, the demand for secondary batteries as energy sources is rapidly increasing. [0005] Secondary batteries are classified into coin-type batteries, cylindrical-type batteries, prismatic-type batteries, and pouch-type batteries according to the shape of the battery case. In such a secondary battery, an electrode assembly insta...
