Secondary Battery Module Having Improved Stability Of Temperature Inside Module

Abstract: The present invention relates to a heat absorption pack for a secondary battery module, and a secondary battery module comprising same. The heat absorption pack comprises a highly absorbent mat having water impregnated inside a pouch and has a structure in which a heat dissipation material is inserted between the highly absorbent mat and the pouch. Accordingly, the heat absorption pack can absorb a large amount of heat from the surroundings when heat is generated inside the module and thus can prevent rapid changes in the ambient temperature of a secondary battery which has the heat absorption pack equipped therein. In addition, the highly absorbent matrix is uniformly exposed to the heat energy in the surroundings and thus can prevent damage to the heat absorption pack due to heat generation inside the module. Therefore, a heat absorption pack comprising same can control the temperature inside the module more stably, thereby improving the performance and stability of the secondary battery, which depend on the ambient temperature.
