Abstract
(EN)
According to the present embodiment, there is provided a non-aqueous electrolyte cell. The non-aqueous electrolyte cell is provided with a positive electrode, a negative electrode, a separator, and a non-aqueous electrolyte. The negative electrode includes a negative-electrode-material layer. The negative-electrode-material layer includes a titanium-containing oxide as a negative electrode active material. The separator is positioned at least between the positive electrode and the negative electrode. The Log differential pore volume distribution curve of the separator according to the mercury intrusion method includes a first peak and a second peak. The first peak is a local maximum at which the pore diameter is within the range of 0.02-0.15 μm. The second peak is a local maximum at which the pore diameter is within the range of 1.5-30 μm. The ratio P2I/P1I of a second peak intensity P2I and a first peak intensity P1I is greater than 1.00 and no more than 3.00. The pore specific surface area according to the mercury intrusion method is 70 m2/g or higher.

Selon le présent mode de réalisation, l'invention concerne une pile à électrolyte non aqueux. La pile à électrolyte non aqueux est pourvue d'une électrode positive, d'une électrode négative, d'un séparateur et d'un électrolyte non aqueux. L’électrode négative comprend une couche de matériau d’électrode négative. La couche de matériau d'électrode négative comprend un oxyde contenant du titane en tant que matériau actif d'électrode négative. Le séparateur est positionné au moins entre l'électrode positive et l'électrode négative. La courbe différentielle logarithmique de répartition volumique des pores du séparateur selon le procédé d’intrusion de mercure inclut une première crête et une seconde crête. La première crête est un maximum relatif auquel le diamètre de pore se situe dans la plage de 0,02 à 0,15 µm. La seconde crête est un maximum relatif auquel le diamètre de pore se situe dans la plage de 1,5 à 30 µm. Le rapport P2I/P1I d'une seconde intensité de crête P2I et d'une première intensité de crête P1I est supérieur à 1,00 et inférieur ou égal à 3,00. La surface spécifique de pore selon le procédé d'intrusion de mercure est supérieure ou égale à 70 m2/g.
