ABSTRACT:
A method of preparing a double layered nickel hydroxide comprising the steps of spraying a first solution of nickel sulfate solution and aqueous ammonia into a first reaction bath, reacting the first solution with sodium hydroxide for a predetermined time to form a core of nickel hydroxide, injecting the core of nickel hydroxide into a second reaction bath, spraying a second solution of nickel sulfate and aqueous ammonia into the second reaction bath, reacting the second solution and sodium hydroxide with the core of nickel hydroxide and growing the core of nickel hydroxide to form an outer layer on the core of nickel hydroxide, the outer layer having a different physical property from the core, is provided.
