Abstract

The invention provides a battery module which includes a battery cell stack, on which plurality of battery cells are stacked, and a heat conduction member disposed on one surface of the battery cell stack. The heat conduction member includes a porous insulating layer and a conductive layer disposed on a surface of the porous insulating layer.

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 secondary batteries 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 such secondary batteries, much research has been conducted on lithium secondary batteries having high energy density and discharge voltage, and recently, lithium secondary batteries have been produced as pouched type battery cells having flexibility , and is used by connecting multiple battery cells to form a module. [0004] A plurality of battery modules are combined to manufacture a battery pack. However, in the related art, in order to increase the energy density of the battery module, cooling...
