Abstract:
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.

US Patent:
6593024, Jul 15, 2003
Filed:
Jun 20, 2002
Appl. No.:
10/176240
Inventors:
Michael A. Fetcenko - Rochester MI
Kwo Young - Troy MI
Cristian Fierro - Northville MI
Assignee:
Ovonic Battery Company, Inc. - Troy MI
International Classification:
H01M 1034
US Classification:
429 60, 4292182, 429223, 429232, 296231
Abstract:
A hydrogen storage battery with improved cycle life and a method for making the same. The battery has a negative electrode with an electrochemically active negative material and a negative electrode capacity and a positive electrode electrochemically coupled with the negative electrode, the positive electrode having a positive electrode capacity and an electrochemically active positive material with a precharge. Also described herein is a positive electrode material for a hydrogen storage battery and a method for making the same. The positive electrode material includes a preoxidized positive active material which is partially non-oxidized. The preoxidized material may be used to provide a precharge to the positive electrode.

US Patent:
7364717, Apr 29, 2008
Filed:
Dec 4, 2003
Appl. No.:
10/727413
Inventors:
Cristian Fierro - Northville MI, US
Gabriel E. Benet - Angola IN, US
Avram Zallen - West Bloomfield MI, US
Tim Hicks - Redford MI, US
Michael A. Fetcenko - Rochester MI, US
Assignee:
Ovonic Battery Company, Inc. - Rochester Hills MI
International Classification:
C01B 17/96
US Classification:
423544, 423146, 4231505
Abstract:
A preferred embodiment of the present invention provides a process for making nickel sulfate by converting nickel metal into nickel sulfate, which may be converted to nickel hydroxide. Nickel metal is dissolved in sulfuric acid and oxygen containing gas is introduced to produce a nickel sulfate solution having nickel sulfate and water as illustrated in the following chemical equation. Ni+HSO+O→NiSO+HOThe nickel sulfate is filtered and sulfuric acid is continually added to maintain stoichiometry within a reactor until the nickel metal is dissolved. The sulfuric acid, oxygen containing gas and nickel metal may be heated to facilitate the desired reaction. Then, the nickel sulfate may be utilized to produce nickel hydroxide.
