HEAT TRANSFER SUPPRESSION SHEET, HEAT TRANSFER SUPPRESSION SHEET FOR BATTERY PACK, AND BATTERY PACK

To provide a heat transfer suppression sheet which is improved in heat transfer suppression effects and also improved in mechanical strength, and a heat transfer suppression sheet for battery pack which is especially suitable for a battery pack.SOLUTION: A heat transfer suppression sheet 1 of the present invention is installed proximately to or at least partially in contact with a heating element 30. The heat transfer suppression sheet 1 comprises a first heat insulation layer 10 and a second heat insulation layer 11, and a metal layer 20 is held between the first heat insulation layer 10 and the second heat insulation layer 11. A heat transfer suppression sheet for a battery pack of the present invention is interposed between battery cells in a battery pack in which multiple battery cells are connected in series or in parallel. The heat transfer suppression sheet for the battery pack comprises a first heat insulation layer and a second heat insulation layer, and while a metal layer is held between the first heat insulation layer and the second heat insulation layer, the metal layer is positioned in a center of the sheet in a sheet thickness direction.SELECTED DRAWING: Figure 1 【課題】熱伝達抑制効果に優れるとともに、機械的強度にも優れた熱伝達抑制シート、特に組電池に適した組電池用熱伝達抑制シートを提供する。【解決手段】本発明の熱伝達抑制シート１は、発熱体３０に近接又は少なくとも一部が接触して設置される熱伝達抑制シート１であって、第１の断熱層１０及び第２の断熱層１１を有し、第１の断熱層１０及び第２の断熱層１１の間に、金属層２０が挟設されている。また、本発明の組電池用熱伝達抑制シートは、複数の電池セルを直列又は並列に接続した組電池における、電池セル間に介在される組電池用熱伝達抑制シートであって、第１の断熱層及び第２の断熱層を有し、第１の断熱層及び第２の断熱層の間に、金属層が挟設されているとともに、金属層が、シート厚み方向における前記シートの中央に位置する。【選択図】図１
