| Zusammenfassung: | To reduce time taken to produce a lithium-containing cobalt oxide having a spinel-type crystal phase.SOLUTION: A method for producing a lithium-containing cobalt oxide having a spinel-type crystal phase includes the steps of: dissolving a metal acetate in an aprotic polar solvent to obtain a mixed solution; vaporizing and drying the mixed solution to obtain a precursor; and burning the precursor. The uniform and particulate precursor is obtained by a vaporizing and drying method using the metal acetate and the aprotic polar solvent, and the precursor is burnt, so that the spinel-type lithium cobaltite can be produced in a short time.SELECTED DRAWING: Figure 1
【課題】スピネル型結晶相を有するリチウム含有コバルト酸化物の製造時間を短縮する。【解決手段】金属酢酸塩をプロトン性極性溶媒に溶解させて混合溶液を得る工程と、混合溶液を蒸発乾固して前駆体を得る工程と、前駆体を焼成する工程とを備える、スピネル型結晶相を有するリチウム含有コバルト酸化物の製造方法とする。金属酢酸塩とプロトン性極性溶媒とを用いた蒸発乾固法により均一かつ微粒子状の前駆体を得て、当該前駆体を焼成することで、短時間でスピネル型コバルト酸リチウムを製造することができる。【選択図】図１ |
