Abstract

L'invention concerne un matériau actif d'électrode positive d'un accumulateur à électrolyte non aqueux qui ne requiert pas de définir une haute tension la première fois que la charge est terminée pour l'accumulateur à électrolyte non aqueux, et peut conférer d'excellentes caractéristiques du cycle de charge-décharge à l'accumulateur à électrolyte non aqueux. Le présent matériau actif d'électrode positive d'un accumulateur à électrolyte non aqueux (1) comporte un premier oxyde et un second oxyde.
