Title (EN) SEPARATOR HAVING FINE PATTERN, WOUND BODY, AND NON-AQUEOUS ELECTROLYTE BATTERY
(FR) SÉPARATEUR AYANT UN MOTIF FIN, CORPS ENROULÉ, ET BATTERIE À ÉLECTROLYTE NON AQUEUX
(JA) 微細パタンを有するセパレータ、捲回体および非水電解質電池
Abstract:
(EN) A separator used for a non-aqueous electrolyte battery comprises a substrate, and a plurality of protruding patterns on at least one principal surface of the substrate, wherein the substrate includes one or more layers, and the value of T1/T2 is 0.3 or more where T1 is the distance between an approximately flat surface formed at the top of the protruding pattern and an approximately flat surface formed at the bottom of the protruding pattern, and T2 is the total thickness of the separator.
(FR) L’invention concerne un séparateur utilisé pour une batterie à électrolyte non aqueux qui comprend un substrat, et une pluralité de motifs en saillie sur au moins une surface principale du substrat, le substrat incluant une ou plusieurs couches, et la valeur de T1/T2 étant supérieure ou égale à 0,3, où T1 est la distance entre une surface approximativement plate formée au sommet du motif en saillie et une surface approximativement plate formée au fond du motif en saillie, et T2 est l’épaisseur totale du séparateur.
(JA) 非水電解質電池に用いられるセパレータが、基材と、該基材の少なくとも一方の主面に複数の凸形状のパタンと、を有し、該基材は、単数又は複数の層を含み、かつ該凸形状のパタンの頂部で形成される略平面と該凸形状のパタンの底部で形成される略平面との距離(T1)、及び該セパレータの総厚(T2)を用いて表されるT1/T2の値が、0.3以上である。
