発明の名称
(EN) RUBBER MOLDED BODY AND BATTERY PACK
(FR) CORPS MOULÉ EN CAOUTCHOUC ET BLOC-BATTERIE
(JA) ゴム成形体及び電池パック
要約
(EN) This rubber molded body is attached to the outer periphery of at least one lithium ion secondary battery cell having a safety valve or an exhaust hole so as to cover at least the safety valve or the exhaust hole, wherein: the thermal conductivity (measurement temperature: 33°C), of the rubber molded body, measured by a steady state comparative-longitudinal heat flow method in accordance with JIS H7903:2008 is less than 1.0 W/m·K; the thickness of a portion that covers the safety valve or the exhaust hole is 0.3-10.0 mm; and the hardness of the surface measured by a Type A durometer on the basis of JIS K6253 is 50-90.
(FR) La présente invention concerne un corps moulé en caoutchouc qui est fixé à la périphérie externe d'au moins une cellule de batterie secondaire au lithium-ion ayant une soupape de sécurité ou un trou d'échappement de manière à recouvrir au moins la soupape de sécurité ou le trou d'échappement, la conductivité thermique (température de mesure : 33 °C), du corps moulé en caoutchouc, mesurée par un procédé de circulation thermique longitudinale comparatif à l'état stable selon la norme JIS H7903:2008 étant inférieure à 1,0 W/m·K; l'épaisseur d'une partie qui recouvre la soupape de sécurité ou le trou d'échappement étant comprise entre 0,3 et 10,0 mm; et la dureté de la surface mesurée par un duromètre de type A conformément à la norme JIS K6253 étant comprise entre 50 et 90.
(JA) 安全弁または排気孔を有する1個以上のリチウムイオン2次電池セルの外周に、少なくとも前記安全弁または前記排気孔を覆うように付設されるゴム成形体であって、JIS H7903:2008に準じて、一方向熱流定常比較法で測定した熱伝導度(測定温度:33℃)が、1.0W/m・K未満であり、前記安全弁または前記排気孔を覆う部分の厚さが、0.3mm以上、10.0mm以下であり、JIS K6253に基づいて、タイプAデュロメータで測定した表面の硬さが、50以上、90以下である。
