Title:
アルミニウム元素勾配分布を有するニッケルコバルトアルミニウム前駆体材料及び正極材料を製造する方法
Document Type and Number:
Japanese Patent JP6395951
Kind Code:
B2
Abstract:
Provided are methods for preparing a nickel-cobalt-aluminum precursor material and a cathode material with a gradient distribution of aluminum element. The precursor material and the cathode material based on the precursor material prepared by the methods are of sphere or sphere-like shapes in which the distribution of the aluminum element is changed in a gradient manner, and the particle size distribution is uniform. The synthesized material has a high tap density, is not sensitive to ambient carbon dioxide and moisture, and has a good processability, a high specific capacity and a good stability property.
