Abstract

Linvention concerne un matériau danode et une batterie. Le matériau danode comprend du graphite artificiel, dont lintérieur et/ou la surface sont poreux. Le matériau danode a une capacité dabsorption dhuile de O mL/100 g, un volume poreux de V cm3 /kg et une surface spécifique de S m2 /g, où 400 ≤ O*V*S ≤ 1500. Le matériau danode améliore les performances dadsorption et dinfiltration de lélectrolyte, et renforce les performances de charge-décharge à régime élevé, sans affecter les performances de préparation.
