Title:
熱伝達抑制シート及び組電池
Document Type and Number:
Japanese Patent JP7332333
Kind Code:
B2
Abstract:
To provide a heat transfer suppression sheet having an excellent heat transfer suppressing effect and having a strength capable of suppressing a decrease in the thickness of a heat insulating material even when the battery cell expands, thereby maintaining high heat insulating performance.SOLUTION: A heat transfer suppression sheet 10 includes a first heat insulating material 20 and a second heat insulating material 30. The thermal conductivity of the first heat insulating material 20 is lower than the thermal conductivity of the second heat insulating material 30. The compressive strength of the second heat insulating material 30 is higher than the compressive strength of the first heat insulating material 20. The first heat insulating material 20 is held by the second heat insulating material 30.SELECTED DRAWING: Figure 1
