Abstract

Cette invention concerne des matériaux composites élaborés sans phase secondaire et à faible coût en utilisant un procédé réactionnel simple qui permet la synthèse de 40 g en une seule manipulation. Les éléments utilisés au départ sont considérés abondants et moins couteux, en plus de leur non-toxicité. Ces nouveaux matériaux sont prometteurs pour une application dans la cathode des batteries, qui permettent datteindre des valeurs de capacité élevées et réversibles ainsi lobtention de plateaux définis au voisinage de 3 V.
