Method Of Making An Aluminum Base Alloy Anode
US Patent:
4865651, Sep 12, 1989
Filed:
May 17, 1988
Appl. No.:
7/194732
Inventors:
Ralph L. Horst - New Kensington PA
Assignee:
Aluminum Company of America - Pittsburgh PA
International Classification:
C22F 104
US Classification:
148 2
Abstract:
An aluminum alloy that may be used as an anode in a battery displays high voltage and high coulombic efficiency when used with a caustic electrode by the presence of about 0. 03 to 0. 2 percent tin. Additionally, about 0. 03 to 0. 07 percent gallium and/or 0. 002 to 0. 006 percent silicon may be added. It is preferred that the purity of the aluminum be at least as pure as 99. 995%. A heat treatment enhances voltage and efficiency.
