Abstract

L'invention concerne une particule d'oxyde de cobalt sphérique poreuse et un procédé pour la préparer. Le procédé de préparation comprend les étapes suivantes consistant à : (1) mélanger une solution de sel de cobalt, de la thio-urée et de l'urée pour former une solution mixte ; (2) chauffer la solution mixte dans l'étape (1) et réaliser une réaction sous une atmosphère aérobie ; (3) réaliser une séparation solide-liquide, et torréfier le produit solide obtenu sous une atmosphère aérobie pour obtenir un matériau torréfié ; et (4) laver et sécher le matériau torréfié obtenu à l'étape (3) pour obtenir la particule d'oxyde de cobalt sphérique poreuse. La particule d'oxyde de cobalt préparée par le procédé de préparation présente une surface spécifique relativement grande, ce qui peut conduire à une augmentation significative de la capacité spécifique d'une batterie.
