HEAT-GENERATING DEVICE FOR BATTERY AND BATTERY ASSEMBLY INCLUDING SAME

摘要

Disclosed are a heat-generating device for a battery and a battery assembly enabling a battery to stably produce electricity even under low-temperature conditions. The heat-generating device for a battery includes a thermal unit positioned on one side of the battery and generates heat via a reaction with the air, wherein the thermal unit comprises a thermal body generating heat via said reaction with the air, and a supporting body wrapping the thermal body to adhere to the battery. Accordingly, the internal temperature of the battery can be maintained within possible activation temperature ranges to allow the battery to produce electricity, thereby making the battery performance sustainable under low-temperature conditions.
