Title:
HEAT-TRANSMISSION CONTROLLING SHEET AND BATTERY PACK
Document Type and Number:
WIPO Patent Application WO/2023/229044
Kind Code:
A1
Abstract:
Provided are: a heat-transmission controlling sheet that, even if a compressive stress applied to the heat-transmission controlling sheet is increased, can maintain heat insulating properties and prevent breakage of the sheet when an adjacent battery cell undergoes thermal runaway; and a battery pack including the heat-transmission controlling sheet.
A heat-transmission controlling sheet (10) includes inorganic particles (4) and organic particles (1), and also includes a plurality of voids (7) which are three-dimensionally linked.
