Abstract

La présente invention concerne un procédé de préparation et une application d'un précurseur d'oxyde de cobalt et de lithium dopé au tellure. Une solution de sel de cobalt, un précipitant et un agent complexant sont ajoutés dans une solution de base pour réaction, le précipitant étant une solution mixte de dioxyde de tellure dissous dans de l'hydroxyde de sodium, et la solution de base étant une solution mixte d'eau ammoniacale et de thiosulfate ; et lorsque le matériau de réaction atteint une taille de particule cible, le matériau de réaction est vieilli, et une séparation solide-liquide est effectuée pour obtenir un précurseur d'oxyde de cobalt et de lithium. Selon la présente invention, le tellure est réduit en anions de tellure au moyen de thiosulfate, du tellurure de cobalt est généré, et un coprécipité est formé avec de l'hydroxyde de cobalt, de telle sorte que le dopage du tellure dans un précurseur est obtenu.The present invention relates to a preparation method and an application of a tellurium-doped lithium cobalt oxide precursor. A cobalt salt solution, a precipitant, and a complexing agent are added into a stock solution for reaction, the precipitant being a mixed solution of tellurium dioxide dissolved in sodium hydroxide, and the stock solution being a mixed solution of ammonia water and thiosulfate; and when the reaction material reaches a target particle size, the reaction material is aged, and solid-liquid separation is performed to obtain a lithium cobalt oxide precursor. According to the present invention, tellurium is reduced into tellurium anions by means of thiosulfate, cobalt telluride is generated, and a coprecipitate is formed with cobalt hydroxide, so that doping of tellurium into a precursor is achieved.
