Abstract

The present invention relates to a storage battery unit, comprising: an electrode assembly; a pouch-shaped casing for accommodating the electrode assembly; Connected to the electrode assembly and the outer lead, wherein the inner lead and the outer lead are connected by a joint, and the joint is broken when the pouch case expands.

Description

technical field [0001] The present invention relates to a battery cell, and more particularly to a pouch-type battery cell capable of interrupting the flow of current in the event of overcharging. Background technique [0002] As portable electronic products such as video cameras, portable phones, and portable PCs are gradually used, the importance of rechargeable batteries used as their driving power is increasing. [0003] Generally, unlike primary batteries that are not charged, rechargeable batteries that can be used for charging and discharging, along with devices such as digital cameras, mobile phones, laptop computers, power tools, electric bicycles, electric vehicles, hybrid vehicles, and large-capacity power The development of high-tech fields such as memory devices has been actively researched. [0004] Specifically, compared with other secondary batteries such as existing lead-acid storage batteries, nickel-cadmium storage batteries, nickel-metal hydride storage ...
