PROBLEM TO BE SOLVED: To establish a method for stably producing cobalt, nickel and lithium manganate powder having excellent uniformity at low cost. SOLUTION: A metal selected from the group consisting of cobalt, nickel and manganese is used as an anode and an oxide, hydroxide or oxyhydroxide of the selected metal is obtained by electrolyzing a lithium salt aqueous solution as an electrolyte. These composite oxides are electrodeposited, and then, if necessary, after adjusting the amount of lithium in the aqueous lithium salt solution as an electrolyte, Preferably, at least one of the selected metal oxides, hydroxides or oxyhydroxides, or an electrodeposit of a composite oxide thereof and an aqueous solution of a lithium salt as an electrolyte are both spray-dried, and Bake and crush. |
