description | PROBLEM TO BE SOLVED: To provide a precursor for obtaining a positive electrode active material for lithium ion battery having excellent battery capacity and excellent cycle characteristics at the same time, and to provide positive electrode active material for lithium ion battery.SOLUTION: A positive electrode active material precursor for lithium ion battery is composed of composite powder precursor secondary particles, containing at least one kind selected from a group consisting of nickel, cobalt and manganese, and formed by aggregation of primary particles having average particle size of 1 μm or less. In the secondary particles, the abundance ratio of particles of 5 μm or less is 20% or less by number conversion based on a dry granularity measurement.SELECTED DRAWING: None
【課題】電池容量及びサイクル特性がいずれも良好なリチウムイオン電池用正極活物質を得るための前駆体及びリチウムイオン電池用正極活物質を提供する。【解決手段】ニッケル、コバルト及びマンガンからなる群から選ばれる少なくとも一種を含み、且つ、平均粒子径が1μm以下の一次粒子が凝集して形成された複合粉末前駆体二次粒子からなり、二次粒子は、乾式粒度測定による個数換算にて5μm以下の粒子の存在割合が20%以下であるリチウムイオン電池用正極活物質前駆体。【選択図】なし |
