Embodiment 1

[0190] (Example 1) Example of nickel manganese cobalt hydroxide

[0191] As the reaction material A, nickel sulfate, manganese sulfate, and cobalt sulfate were prepared into a 1.6 M liquid at a ratio of 1:1:1. As the reaction material B, 25% concentration of sodium hydroxide was used, and as the reaction material C, 25% concentration of ammonia water was used. In order to carry out a specific reaction, ammonium sulfate, hydrogen peroxide, ethanol, glycerin, etc. were added to the reaction material A to adjust the solvent, and an example in which 0.1 M ammonium sulfate was added is shown here.
