Abstract:
(EN) Provided is a sulfur-carbon material composite body which enables a secondary battery to be less susceptible to deterioration in the cycle characteristics during charging and discharging of the secondary battery if this sulfur-carbon material composite body is used for an electrode of the secondary battery. A sulfur-carbon material composite body that contains: a first carbon material which has a graphene multilayer structure; a spacer which is at least partially arranged between graphene layers or at an end of the first carbon material; and sulfur or a compound containing sulfur, which is at least partially arranged between graphene layers or at an end of the first carbon material.
(FR) L'invention concerne un corps composite de matériau soufre-carbone qui permet à une batterie secondaire d'être moins susceptible de se détériorer dans les caractéristiques de cycle pendant la charge et la décharge de la batterie secondaire si ce corps composite de matériau soufre-carbone est utilisé pour une électrode de la batterie secondaire. Un corps composite de matériau soufre-carbone qui contient : un premier matériau carboné qui a une structure multicouche de graphène; un espaceur qui est au moins partiellement disposé entre des couches de graphène ou à une extrémité du premier matériau carboné; et du soufre ou un composé contenant du soufre, qui est au moins partiellement disposé entre des couches de graphène ou à une extrémité du premier matériau carboné.
(JA) 二次電池の電極に用いたときに、二次電池の充放電時におけるサイクル特性を劣化させ難い、硫黄-炭素材料複合体を提供する。 グラフェン積層構造を有する第1の炭素材料と、第1の炭素材料のグラフェン層間又は端部に少なくとも一部が配置されている、スペーサーと、第1の炭素材料のグラフェン層間又は端部に少なくとも一部が配置されている、硫黄又は硫黄を含む化合物と、を含む、硫黄-炭素材料複合体。
