Abstract

A battery module includes at least one battery cell; a first plate disposed on one side of the at least one battery cell to dissipate heat generated by the at least one battery cell externally; and asecond plate disposed on the other side of the at least one battery cell to dissipate heat generated by the at least one battery cell externally, wherein an electrode lead of the at least one batterycell is disposed between the first plate and the second plate, and is disposed to be biased toward the first plate.

Description

technical field [0001] The invention relates to a battery module. Background technique [0002] Unlike primary batteries, secondary batteries can be charged and discharged, so they can be used in various fields such as digital cameras, mobile phones, notebook computers, and hybrid vehicles. The secondary battery may include a nickel-cadmium battery, a nickel-metal hydride battery, a nickel-hydrogen battery, a lithium secondary battery, and the like. [0003] Among the secondary batteries as described above, various studies are being conducted on lithium secondary batteries having high energy density and discharge voltage, and recently used lithium secondary batteries are produced as pouched type batteries having flexibility unit, and form a module form by connecting multiple battery units. [0004] On the other hand, when the battery module is used for a long time, the battery will generate heat. In particular, the internal temperature will rise sharply during charging. Th...
