Title (EN) ELECTRICITY STORAGE ELEMENT AND METHOD FOR PRODUCING SAME
(FR) ÉLÉMENT DE STOCKAGE D’ÉLECTRICITÉ ET SON PROCÉDÉ DE FABRICATION
(JA) 蓄電素子およびその製造方法
Abstract:
(EN) Provided is an electricity storage element which has improved output performance with a relatively large current. One embodiment of the present invention provides an electricity storage element which comprises a negative electrode active material layer containing a particulate amorphous carbon, and wherein: the differential pore volume distribution curve of the negative electrode active material layer has a peak within the range from 0.1 μm to 2 μm (inclusive); and the differential pore volume at the peak is 0.9 cm3/g or more.
(FR) L'invention concerne un élément de stockage d'électricité qui a des performances de sortie améliorées avec un courant relativement important. Un mode de réalisation de la présente invention concerne un élément de stockage d'électricité qui comprend une couche de matériau actif d'électrode négative contenant un carbone amorphe particulaire, et dans lequel : la courbe de distribution de volume de pore différentiel de la couche de matériau actif d'électrode négative a un pic dans la plage de 0,1 µm à 2 µm (inclus) ; et le volume de pore différentiel au pic est supérieur ou égal à 0,9 cm3/g.
(JA) 比較的大きい電流での出力性能が向上された蓄電素子を提供する。本実施形態では、粒子状の非晶質炭素を含有する負極活物質層を有し、負極活物質層の微分細孔容積の分布曲線は、0.1μm以上2μm以下の範囲にピークを有し、該ピークの微分細孔容積は、0.9cm/g以上である、蓄電素子を提供する。
