Summary:This negative electrode material for a lithium ion secondary cell includes carbonaceous particles that have a BET-method specific surface area (water-vapor-adsorption specific surface area) of 0.095 m2/g or less as calculated from the amount of water vapor adsorbed when the relative pressure is 0.05-0.12. Le matériau d'électrode négative pour batterie secondaire au lithium-ion de l'invention contient des particules carbonées qui présentent une surface spécifique de méthode BET (surface spécifique d'adsorption de vapeur d'eau) calculée à partir d'une quantité d'adsorption de vapeur d'eau lorsque la pression relative est comprise entre 0,05 et 0,12, inférieure ou égale à 0,095m2/g. リチウムイオン二次電池用負極材は、相対圧が0.05~0.12のときの水蒸気吸着量から算出したBET法比表面積(水蒸気吸着比表面積)が0.095m2/g以下である炭素性粒子を含む。
