Beschreibung
Zusammenfassung:The invention relates to a preparation method of large-particle-size aluminum-coated cobaltosic oxide. The preparation method comprises the following steps of solution preparation, synthetic reaction, aluminum source coating, filtering, washing and drying. According to the invention, through application of an additive, rapid growth of particles is realized; and the coated aluminum source can be uniformly distributed in the cobaltosic oxide, so that the hydroxyl coated aluminum source is successfully realized. 一种大粒径包铝四氧化三钴的制备方法，包括以下步骤：溶液的配制，合成反应，包覆铝源，过滤、洗涤及干燥。本发明通过添加剂的应用，实现了颗粒的快速长大；所包覆铝源能均匀分布在四氧化三钴里，成功实现了羟基系包覆铝源。
