Abstract
A precipitating agent is added to an aqueous solution of a nickel salt to prepare a first slurry of nickel hydroxide fine particles, polyvinylpyrrolidone is added to the first slurry to prepare a second slurry of composite fine particles including nickel hydroxide fine particles and polyvinylpyrrolidone, and composite fine particles are obtained by being separated from the second slurry.
Claims8
A method for manufacturing composite fine particles of nickel and polyvinylpyrrolidone, the method comprising:
- obtaining a first slurry that is an aqueous slurry of nickel hydroxide fine particles by adding a precipitating agent to an aqueous solution of a nickel salt;
- obtaining a second slurry that is an aqueous slurry including the nickel hydroxide fine particles and polyvinylpyrrolidone by adding polyvinylpyrrolidone to the first slurry;
- and
- obtaining the composite fine particles of the nickel hydroxide fine particles and polyvinylpyrrolidone or composite fine particles of nickel oxide fine particles and polyvinylpyrrolidone by separating the composite fine particles of the nickel hydroxide fine particles and polyvinylpyrrolidone from the second slurry,
- wherein the obtaining the composite fine particles further includes
- obtaining a solid material by drying the second slurry and
- disintegrating the solid material.
