Abstract
Official abstract text for this publication.
A nickel hydroxide for an alkaline secondary battery, wherein the nickel hydroxide contains α-nickel hydroxide particles and β-nickel hydroxide particles, and the ratio of the β-nickel hydroxide to the total amount of the nickel hydroxide is less than 75% by mass.
First claim
Opening claim text (preview).
What is claimed is: 1. A nickel hydroxide, wherein the nickel hydroxide contains α-nickel hydroxide particles and β-nickel hydroxide particles, the α-nickel hydroxide particles and the β-nickel hydroxide particles independently existing in the nickel hydroxide, the ratio of the β-nickel hydroxide to the total amount of the nickel hydroxide is less than 75% by mass, and the average particle size of the β-nickel hydroxide particles is smaller than that of the α-nickel hydroxide particles. 2. The nickel hydroxide according to claim 1 , wherein the ratio of the β-nickel hydroxide to the total amount of the nickel hydroxide is 50% by mass or less. 3. An alkaline secondary battery comprising the nickel hydroxide according to claim 1 . 4. A nickel hydroxide, wherein the nickel hydroxide contains α-nickel hydroxide particles and β-nickel hydroxide particles, the α-nickel hydroxide particles and the β-nickel hydroxide particles independently existing in the nickel hydroxide, the average particle size of the β-nickel hydroxide particles is smaller than that of the α-nickel hydroxide particles, and the α-nickel hydroxide particles are contained at an amount of 50% by mass or more in the α-nickel hydroxide particles and β-nickel hydroxide particles.
