Abstract
La présente invention concerne un procédé de préparation d'un précurseur d'oxyde de cobalt et de lithium à base d'étain, et une application du précurseur. Le procédé de préparation comprend : l'ajout d'une solution de sel de cobalt, d'un précipitant et d'un agent complexant pour une réaction permettant d'obtenir un précipité, le précipitant étant une solution mixte de carbonate et de stannate ; la calcination du précipité ; le mélange du matériau calciné avec du dioxane, et la réalisation d'un broyage à boulets ; et le chauffage et la mise sous pression du produit broyé à boulets pour obtenir le précurseur d'oxyde de cobalt et de lithium à base d'étain. Dans la présente invention, par mélange de carbonate et de stannate avec un sel de cobalt, un co-précipité de carbonate de cobalt et de stannate de cobalt est généré ; un mélange d'oxyde cobaltosique et de dioxyde d'étain est formé après calcination ; le dioxane est utilisé pour effectuer un pressage à chaud de solvant, de telle sorte que des particules sont liées les unes aux autres, et un canal de limite de grain est formé, ce qui permet d'améliorer la conductivité d'un matériau tandis que l'étain est dopé.
