Title:
板状水酸化ニッケル粒子、その製造方法及びこれを原料とするリチウム・ニッケル複合酸化物粒子の製造方法
Document Type and Number:
Japanese Patent JP4066472
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide platy nickel hydroxide particles each having a large primary particle diameter capable of comfortably be used for producing a positive electrode material of a non-aqueous electrolytic lithium ion secondary cell and a method for producing the platy particles. SOLUTION: This platy nickel hydroxide particle has an average major axis diameter of a primary particle within the range of 1-50 μm and an average thickness within the range of 0.1-10 μm, and a specific surface area by an N2 -BET method within the range of 0.1-5 m<2> /g. The platy nickel hydroxide particle is produced by heating a usual granular (spherical) nickel hydroxide particle or a nickel salt in an aqueous solution of ammonia, an alkali hydroxide and an ammonium salt at 120-350 deg.C.
