Title:
HEAT TRANSFER SUPPRESSION SHEET FOR ASSEMBLED BATTERY AND ASSEMBLED BATTERY
Document Type and Number:
Japanese Patent JP2022152840
Kind Code:
A
Abstract:
To provide a heat transfer suppression sheet for an assembled battery which is used in an assembled battery in which a plurality of battery cells are connected in series or in parallel, efficiently diffuses the heat generated in the battery cells to the outside of the heat transfer suppression sheet during normal use, and can prevent a chain of thermal runaway by suppressing heat transfer between battery cells in the event of an abnormality.SOLUTION: A heat transfer suppression sheet 10 for an assembled battery is used in an assembled battery in which a plurality of battery cells are connected in series or in parallel, is provided between the battery cells, and includes a pair of heat insulators 11a and 11b, and at least one high thermal conductivity layer 12a disposed between the heat insulators. The heat conductivity of the high thermal conductivity layer 12a is higher than that of the heat insulator, and the thickness of the high thermal conductivity layer 12a increases toward the one end surface side. The high thermal conductivity layer 12a is exposed on one end surface side of the heat transfer suppression sheet 10.SELECTED DRAWING: Figure 1
