Problems solved by technology

[0005] However, due to heat radiation away from the lead lugs and the battery fuse, the battery fuse does not blow properly in the low current region (eg, less than 2000A) compared to the high current region in the current range where the battery fuse needs to blow

Abstract

A rechargeable battery includes: an electrode assembly; a case housing the electrode assembly, the case comprising a side wall and having a case opening; a terminal coupled to the electrode assembly; a lead tab coupled between the terminal and the electrode assembly, the lead tab comprising a cell fuse; and a thermal insulation member at a portion of the lead tab adjacent the case opening and another portion of the lead tab adjacent the side wall.

Description

technical field [0001] Embodiments of the present invention relate to a rechargeable battery in which a battery fuse is included in a lead tab. Background technique [0002] Unlike primary batteries that are not designed to be recharged, rechargeable batteries are batteries that can repeatedly perform charging and discharging. Small-capacity rechargeable batteries are used for portable small electronic devices such as mobile phones, portable computers, and camcorders, and large-capacity rechargeable batteries are used as power sources for driving motors of hybrid and / or electric vehicles. [0003] For example, a rechargeable battery includes an electrode assembly for performing charging and discharging, a case for accommodating an electrolytic solution and the electrode assembly, a cap plate coupled to an opening of the case, and a cap for electrically connecting the electrode assembly to an electrode terminal. Lead lugs. [0004] In the rechargeable battery, the lead tab ...
