Problems solved by technology

[0008] However, the electrodes of the rechargeable battery may be damaged by arc or heat generated when the fuse breaks due to abnormal current
[0009] In addition, if the fuse contacts other elements of the rechargeable battery, when an abnormal current passes through the fuse, an abnormal operation in which the fuse breaks at a temperature higher or lower than a predetermined temperature at which the fuse is to break may occur

Abstract

A rechargeable battery includes an electrode assembly; a case housing the electrode assembly; and an electrode connection assembly electrically coupled to the electrode assembly, the electrode connection assembly including: a terminal; a current collector electrically coupled to the electrode assembly; an insulating member between the terminal and the current collector, wherein a portion of the insulating member is spaced from the terminal and the current collector; and a connection member electrically coupling the terminal and the current collector, the connection member including a fuse part, wherein the portion of the insulating member overlaps with the connection member.

Description

technical field [0001] The described technology relates generally to rechargeable batteries. Background technique [0002] Unlike primary batteries, which cannot be recharged, rechargeable batteries are batteries that can be discharged and recharged. Low-capacity rechargeable batteries have been used for portable small electronic devices such as mobile phones, laptop computers, and camcorders, while large-capacity batteries have been used for driving batteries such as those used in hybrid vehicles. A power source for the motor or a bulk power storage device. [0003] In recent years, high-output rechargeable batteries using non-aqueous electrolytes with high energy density have been developed. A high-output rechargeable battery is configured as a large-capacity battery module by connecting a plurality of rechargeable batteries in series so that it can be used to drive a motor of a device requiring high power, such as an electric car. Rechargeable batteries may be formed a...
