Problems solved by technology

[0007] However, the pouch type battery is not durable against external shocks and does not dissipate heat easily
In addition, since a pouch-type battery does not have a structure to fix its external shape, it is difficult to manufacture a pouch-type battery by stacking using battery modules
[0008] Metal can type batteries are strong but heavy and difficult to dissipate internal heat to the outside

Abstract

A rechargeable battery is disclosed. It comprises a case having a recess and an electrode assembly disposed within said recess, wherein the case includes a heat dissipating flange to disspate heat generated by the battery.

Description

technical field [0001] The technology described generally relates to rechargeable batteries and battery modules. More specifically, the described technology generally relates to rechargeable batteries and battery modules with improved structural housings. Background technique [0002] Unlike primary batteries, which cannot be recharged, rechargeable batteries can be recharged and discharged. Low-capacity rechargeable batteries are commonly used as power sources for small portable electronic devices such as mobile phones, laptop computers, and camcorders, while large-capacity rechargeable batteries are commonly used for driving e.g. hybrid The power supply of the electric motor of the power car. [0003] Large-capacity high-power rechargeable batteries with high energy density using non-aqueous electrolytes have been developed, and rechargeable batteries are generally formed by connecting multiple rechargeable batteries in series or in parallel in a large-capacity high-powe...
