Abstract

A rechargeable battery comprises a housing, an electrode subassembly being accommodated in the housing and having a first flat surface, a second flat surface and a connecting part connecting the first flat surface and the second flat surface; and a supporting plate located between the housing and the electrode subassembly, wherein the supporting plate is electrically connected to the electrode subassembly and has a flat part adjacent to and overlapping with either the first flat surface or second flat surface.

Description

technical field [0001] The present disclosure relates to rechargeable batteries, and more particularly to rechargeable batteries including safety devices. Background technique [0002] Unlike primary batteries, which cannot be recharged, rechargeable batteries can be recharged and discharged. Low-capacity rechargeable batteries are often used in small portable electronic devices such as mobile phones, laptop computers, and camcorders, while high-capacity rechargeable batteries are often used to power batteries such as hybrid vehicles. Power supply for the motor. [0003] Recently, a large-capacity high-power rechargeable battery using a high-energy-density non-aqueous electrolyte has been developed. The aforementioned large-capacity rechargeable battery is formed into a large-capacity battery module by connecting a plurality of these rechargeable batteries in series or parallel in order to use the large-capacity rechargeable battery to drive, for example, a motor in an ele...
