Abstract: An electrode assembly, in which positive electrodes, separators, and negative electrodes are repeatedly stacked, and a positive electrode tab, through which the positive electrodes are connected to each other, and a negative electrode tab, through which the negative electrodes are connected to each other, are provided, includes a heat transfer layer made of a material having thermal conductivity greater than that of the separator and stacked between the positive electrode and the separator or between the negative electrode and the separator to disperse heat generated at a relatively high temperature point to a relatively low temperature point.

Abstract: A battery module assembly includes a battery module and a cooling plate attached to the battery module, wherein the battery module has a first paste injection hole for injecting a thermal paste into the battery module and a first paste discharge hole for discharging the thermal paste out of the battery module, and wherein the cooling plate has a second paste injection hole formed at a location corresponding to the first paste injection hole and a second paste discharge hole for allowing the thermal paste discharged out of the battery module through the first paste discharge hole to be discharged out of the battery module assembly.

Abstract: According to the present disclosure, there is a cooling device for battery cells including a heat sink with a hollow structure disposed adjacent to at least one side of a battery cell assembly and having a channel formed therein through which a coolant flows, the battery cell assembly including a plurality of battery cells, and a cooling plate configured to carry out heat exchange with the battery cells, the cooling plate including a heat absorbing part interposed between the battery cells such that one surface or both surfaces come into contact with the battery cells, and a heat emitting part extending from the heat absorbing part and exposed to the channel, wherein the heat emitting part includes at least one bent surface arranged parallel to the channel, and at least one through-hole through which the coolant goes.
