Title:
COBALT-COATED NICKEL-CONTAINING HYDROXIDE PARTICLE
Document Type and Number:
Japanese Patent JP2021195297
Kind Code:
A
Abstract:
To provide a cobalt-coated nickel-containing hydroxide particle having excellent particle strength, thereby capable of preventing a break or crack in the particle and formation of fine powder.SOLUTION: In a cobalt-coated nickel-containing hydroxide particle, a coating layer involving cobalt oxyhydroxide is formed on a nickel-containing hydroxide particle. In the cobalt-coated nickel-containing hydroxide particle, the average size of 10 particles whose particle strength has been measured is 10.0 μm or over and 11.5 μm or under, and the cobalt-coated nickel-containing hydroxide particles have an average particle strength of 65.0 MPa or over and 100.0 MPa or under.SELECTED DRAWING: None
