A rechargeable nonaqueous electrolyte secondary battery has a positive electrode which can be doped with lithium ions and de-doped thereof, a nonaqueous electrolyte solution and a negative electrode. The negative electrode active material is a carbon material including at least two component: (a) flake graphite particles; and (b) a non-flake graphite material whose surface is covered with amorphous carbon. This secondary battery has a high capacity and is excellent charging/discharging efficiency.
Cet accumulateur à électrolyte non aqueux, rechargeable, comprend une plaque positive que l'on peut doper au moyen d'ions lithium ou dont on peut supprimer le dopage au moyen de ces ions, un électrolyte non aqueux, ainsi qu'une électrode négative. Le matériau actif de la plaque négative est une matière carbonée contenant au moins deux composants: (a) des particules de graphite en paillettes, et (b) un graphite non en paillettes, dont la surface est recouverte de carbone amorphe. Cet accumulateur possède une capacité élevée, ainsi qu'une excellente caractéristique de charge/décharge.
