Title (EN) POWER STORAGE ELEMENT
(FR) ÉLÉMENT DE STOCKAGE D'ÉLECTRICITÉ
(JA) 蓄電素子
Abstract:
(EN) A power storage element is provided which has sufficient energy density and sufficient output. This power storage element is provided with a negative electrode that has an active material layer containing an active material. The active material layer contains particulate graphite as the active material, and the particle diameter frequency distribution of the graphite has a first peak, and a second peak appearing at a greater particle diameter than that of the first peak. The particle diameter at the first peak is 10 μm or less, and the particle diameter at the second peak is greater than 10 μm. The active material layer further contains a particulate high hardness active material which has a higher hardness than that of the graphite
(FR) La présente invention porte sur un élément de stockage d'électricité présentant une densité d'énergie suffisante et une puissance suffisante. Ledit élément de stockage d'électricité est pourvu d'une électrode négative qui comporte une couche de substance active contenant une substance active. La couche de substance active contient du graphite particulaire comme substance active, et la distribution de fréquence de diamètre de particule du graphite présente un premier pic, et un second pic apparaissant à un diamètre de particule supérieur à celui du premier pic. Le diamètre de particule au niveau du premier pic est inférieur ou égal à 10 µm, et le diamètre de particule au niveau du second pic est supérieur à 10 μm. La couche de substance active contient une substance active particulaire à haute dureté qui présente une dureté supérieure à celle du graphite.
(JA) エネルギー密度を十分に有し且つ出力を十分に有する蓄電素子を提供する。本実施形態では、活物質を含む活物質層を有する負極を備え、活物質層は、粒子状のグラファイトを活物質として含み、グラファイトの粒径頻度分布は、第1のピークと、該第1のピークよりも粒子径が大きい方に現れる第2のピークとを有し、前記第1のピークの粒子径は、10μm以下であり、前記第2のピークの粒子径は、10μmよりも大きく、活物質層は、グラファイトよりも硬度が高い粒子状の高硬度活物質をさらに含む、蓄電素子を提供する。
