(FR) FEUILLE D'ALUMINIUM ET DISPOSITIF DE STOCKAGE D'ÉNERGIE
(JA) アルミニウム箔、及び蓄電デバイス
Abstract:
(EN) Provided is an aluminum foil having excellent penetrability and handling properties (mechanical strength). According to the present invention, the thickness of the aluminum foil is greater than 0 μm and equal to or less than 50 μm; a plurality of through-holes extend from the surface of the aluminum foil to the rear surface; the number of the through-holes having a diameter of 1-100 μm is 10/mm2 or more per unit area of the aluminum foil; the tensile strength of the aluminum foil is 50 N/mm2 or more; the wear rate RM is defined by {(M0-M1)/M0}X100, where the mass of the aluminum foil before forming the through-holes is represented by M0, and the mass of the aluminum foil after forming the through-holes is represented by M1; the aperture ratio is defined by (A1/A0)X100, where the surface area of the aluminum foil is represented by A0, and the total aperture area of the through-holes formed in the surface of the aluminum foil is represented by A1; and (RA/RM)X100 is 80-100%.
(FR) L'invention concerne une feuille d'aluminium ayant d'excellentes propriétés de pénétrabilité et de manipulation (résistance mécanique). Selon la présente invention, l'épaisseur de la feuille d'aluminium est supérieure à 0 µm et inférieure ou égale à 50 µm ; une pluralité de trous traversants s'étendent depuis la surface de la feuille d'aluminium jusqu'à la surface arrière ; le nombre des trous traversants ayant un diamètre de 1 à 100 µm est supérieur ou égal à 10/mm2 par unité de surface de la feuille d'aluminium ; la résistance à la traction de la feuille d'aluminium est supérieure ou égale à 50 N/mm2 ; le taux d'usure RM est défini par {(M0-M1)/M0}X100, où la masse de la feuille d'aluminium avant la formation des trous traversants est représentée par M0, et la masse de la feuille d'aluminium après la formation des trous traversants est représentée par M1 ; le rapport d'ouverture est défini par (A1/A0)X100, où la surface de la feuille d'aluminium est représentée par A0, et la zone d'ouverture totale des trous traversants formés dans la surface de la feuille d'aluminium est représentée par A1 ; et (RA/RM)X100 est de 80 à 100 %.
(JA) 貫通性及びハンドリング性(機械的強度)に優れたアルミニウム箔が提供される。アルミニウム箔の厚さが0μmより大きく50μm以下であり、複数の貫通孔がアルミニウム箔の表面から裏面へ延びており、直径が1μm以上100μm以下である貫通孔の数が、アルミニウム箔の単位面積当たり、10個/mm以上であり、アルミニウム箔の引張強度が50N/mm以上であり、貫通孔が形成される前のアルミニウム箔の質量がM0と表され、貫通孔が形成された後のアルミニウム箔の質量がM1と表され、減耗率RMが、{(M0-M1)/M0}×100と定義され、アルミニウム箔の表面の面積がA0と表され、アルミニウム箔の表面に形成された貫通孔の開口面積の合計がA1と表され、開口率RAが、(A1/A0)×100と定義され、(RA/RM)×100が、80%以上100%以下である。
