RECHARGEABLE BATTERY

摘要

A rechargeable battery that simplifies a structure that implements an external short circuit and that reduces a production cost is provided. The rechargeable battery includes: an electrode assembly that is formed by spiral-winding a first electrode and a second electrode that are disposed at respective surfaces of a separator interposed therebetween; a case that houses the electrode assembly; a cap plate that closes and seals an opening of the case; a first electrode terminal that is connected to the first electrode and that is installed in an insulation state in the cap plate; a second electrode terminal that is connected to the second electrode and that is electrically connected to the cap plate; and a vent plate that is installed in a vent hole of the cap plate and that is short-circuited with the first electrode terminal when the vent hole is opened.
