摘要： A process for making a positive battery electrode material using a secondary metal. The secondary metal is preferably treated using a non-electrolytic process and formed into an active, positive battery electrode material by a precipitation reaction. Also disclosed herein is a process for making a nickel hydroxide material without the necessity of a preamine reactor. The process includes the steps of providing a metal and forming the metal into an active positive electrode material. The process for making a nickel hydroxide material may also include one or more blending steps. The step for forming may include concurrently combining the metal with ammonium ions and hydroxide ions. The step for forming may also include a continuously stirred precipitation reaction of metal ions. In a preferred aspect of the process hereof, the metal may be a secondary nickel source, such as a spent or virgin electrolyte solution from a nickel electrorefining process, nickel electroless plating process or nickel electroplating process.
