Title (EN) SECONDARY BATTERY INSULATING PLATE AND SECONDARY BATTERY EQUIPPED WITH SAME
(FR) PLAQUE ISOLANTE DE BATTERIE SECONDAIRE ET BATTERIE SECONDAIRE ÉQUIPÉE DE CELLE-CI
(JA) 二次電池用絶縁板およびそれを備える二次電池
Abstract:
(EN) This insulating plate is for use in a secondary battery that is provided with a wound-type electrode group, an electrolyte, a cylindrical battery case for housing the electrode group and the electrolyte, and a sealing body which seals an opening of the battery case and which is provided with an air release valve. The insulating plate is disposed between the electrode group and the sealing body and has a discoid shape of at least 0.1 mm in thickness T. The insulating plate has a first hole formed in the center thereof and at least one second hole formed around the first hole so as to extend along the outer circumference of the discoid shape. The ratio (=T/D) of the thickness T to the diameter D of the insulating plate is at most 0.016, and the insulating plate has an opening ratio of at most 36%.
(FR) L'invention concerne une plaque isolante destinée à être utilisée dans une batterie secondaire qui comprend un groupe d'électrodes de type enroulé, un électrolyte, un boîtier de batterie cylindrique pour loger le groupe d'électrodes et l'électrolyte, et un corps d'étanchéité qui scelle une ouverture du boîtier de batterie et qui comprend une soupape de libération d'air. La plaque isolante est disposée entre le groupe d'électrodes et le corps d'étanchéité et a une forme discoïdale d'au moins 0,1 mm en épaisseur T. La plaque isolante a un premier trou formé dans son centre et au moins un second trou formé autour du premier trou de façon à s'étendre le long de la circonférence extérieure de la forme discoïde. Le rapport (= T/d) de l'épaisseur T au diamètre d de la plaque isolante est d'au plus 0,016, et la plaque isolante a un rapport d'ouverture d'au plus 36 %.
(JA) 絶縁板は、巻回式の電極群と、電解質と、前記電極群および前記電解質を収容する円筒形の電池ケースと、前記電池ケースの開口部を封口するとともに、排気弁を備える封口体と、を備える二次電池用の絶縁板である。前記絶縁板は、前記電極群と前記封口体との間に配置され、0.1mm以上の厚みTを有する円盤形状を有する。前記絶縁板は、中央に形成された第1孔と、前記第1孔の周囲に、前記円盤形状の外周に沿うように形成された少なくとも1つの第2孔とを備える。前記厚みTの前記絶縁板の直径Dに対する比率(=T/D)は、0.016以下であり、前記絶縁板の開口率は、36%以下である。
