  • Publication number: 20260011813
    Abstract: A heat absorbing pack for a secondary battery module includes a super absorbent matrix and a heat-dissipating structure. The super absorbent matrix is impregnated with water inside the pouch and the heat-dissipating substrate is inserted between the super absorbent matrix and the pouch, so that it can absorb a large amount of heat from the surroundings when heat is generated inside the module. Therefore, it is possible to prevent the ambient temperature of the secondary battery from changing rapidly. Furthermore, the super absorbent matrix can be uniformly exposed to ambient thermal energy to prevent damage to the heat absorbing pack due to heat generation inside the module. Accordingly, the heat absorbing pack provides more stable temperature control inside the module, which can improve the performance and stability of the secondary battery according to the ambient temperature. A secondary battery module including the same is also provided.

    Abstract: A heat absorbing pack for a secondary battery module and a secondary battery module including the same are provided. The heat absorbing pack has a structure including a superabsorbent matrix impregnated with water inside a pouch, and a heat-dispersing structure is inserted between the superabsorbent matrix and the pouch. Accordingly, the heat absorbing pack can absorb a large amount of heat from the surroundings when heat is generated inside the module, and thus, when it is provided in a secondary battery module, it is possible to prevent a rapid change in the ambient temperature of the secondary battery. Furthermore, the superabsorbent matrix of the heat absorbing pack can be uniformly exposed to the heat energy of the surroundings to prevent damage to the heat absorbing pack due to heat generation inside the module.
