Problems solved by technology

[0005] However, the cover plate is conventionally formed to have a flat shape, so the cover plate cannot quickly transfer the gas that can increase the internal pressure immediately or quickly to the vent plate
Therefore, the rechargeable battery can explode before the internal pressure builds up immediately or rapidly enough to rupture the vent panel

Abstract

A rechargeable battery for improving stability by quickly transmitting generated gas to a vent plate when an internal short circuit occurs, the rechargeable battery including: an electrode assembly including a first electrode, a second electrode, and a separator between the first and second electrodes; a case containing the electrode assembly; and a cap plate sealing an opening of the case and including an electrode terminal connected to the electrode assembly, the cap plate further including a round unit arranged at an inner side of the case.

Description

technical field [0001] Aspects of embodiments of the invention relate to a rechargeable battery. Background technique [0002] Unlike primary batteries, rechargeable batteries can repeatedly perform charging and discharging. A small-capacity rechargeable battery can be used in portable small-sized electronic devices such as mobile phones, notebook computers, and camcorders, and a large-capacity rechargeable battery can be used as an electric motor for driving a motor such as a motor for a hybrid vehicle. power supply. [0003] For example, a rechargeable battery includes an electrode assembly, a case for accommodating the electrode assembly, a cover plate combined to an opening of the case, and an electrode terminal installed in the cover plate and connected to the electrode assembly. The cover plate includes a terminal hole for installing electrode terminals and a vent hole, and a vent plate thinner than the cover plate is welded in the vent hole. When the internal press...
