THERMAL BATTERY WITH ACTIVE INSULATING STRUCTURE

摘要

The present invention relates to a thermal battery with an active insulating structure capable of greatly improving stability and the operation time of the thermal battery by applying a bidirectional active insulating structure to the thermal battery and by maintaining the inner temperature of the thermal battery with minimum operation temperate or more for a long time. According to one embodiment of the present invention, the thermal battery with an active insulating structure, in a thermal battery including a battery stack part formed by stacking unit batteries which are activated by a heat source, includes a first heat supply part located in the first surface of the battery stack part; and a second heat supply part located on the second surface of the battery stack part.
