Abstract

 Linvention concerne un matériau danode et une batterie, le matériau danode comprenant du graphite artificiel. Lintérieur et/ou la surface du graphite artificiel est poreux, et le matériau danode présente un volume poreux de V cm³/kg, une surface spécifique de S m²/g et une densité apparente de T g/mL, où 8,5 ≤ V*S/T ≤ 27. Le matériau danode et la batterie selon la présente invention permettent daméliorer les performances électrochimiques du matériau danode tout en garantissant ses performances de traitement.
