  • Method of making an aluminum base alloy anode
    Patent number: 4865651
    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.
    Type: Grant
    Filed: May 17, 1988
    Date of Patent: September 12, 1989
    Assignee: Aluminum Company of America
    Inventor: Ralph L. Horst
