Abstract

La présente invention concerne une méthode de préparation d'oxyde cobaltosique dopé et revêtu d'étain et son utilisation. La méthode de préparation comprend : l'ajout d'une solution de sel de cobalt, d'une solution alcaline d'étain et d'eau ammoniacale dans une solution de base en parallèle pour réaction ; lorsque le matériau de réaction atteint une taille de particule cible, le vieillissement du matériau de réaction ; la réalisation d'une séparation solide-liquide pour obtenir un précipité ; la calcination du précipité en l'absence d'oxygène, puis la calcination en présence d'oxygène pour obtenir l'oxyde cobaltosique dopé et revêtu d'étain. L'oxyde cobaltosique dopé et revêtu d'étain de la présente invention améliore la stabilité du réseau cristallin du matériau principal, et la surface de revêtement de dioxyde d'étain peut réduire la dissolution de cobalt par un électrolyte, de telle sorte que les performances de cycle du matériau sont améliorées.The present invention relates to a preparation method for tin-doped and coated cobalt oxide and a use thereof. The preparation method comprises: adding a cobalt salt solution, an alkaline tin solution and ammonia water into a base solution in parallel for reaction; when the reaction material reaches a target particle size, aging the reaction material; performing solid-liquid separation to obtain a precipitate; calcining the precipitate in the absence of oxygen, and then calcining in the presence of oxygen to obtain the tin-doped and coated cobalt oxide. The tin-doped and coated cobalt oxide of the present invention improves the crystal lattice stability of the main material, and the tin dioxide coating surface can reduce the dissolution of cobalt by an electrolyte, so that the cycle performance of the material is improved.
