For making battery electrodes, a composite strip of a cast ribbon of an electrically conductive metal attached to and extending along an edge of a web of electrically conductive carbon fiber material, also called a carbon felt in some examples, with a plurality of spaced apart notches cast in the ribbon and opening to an edge of the ribbon spaced from the carbon fiber material. A rotatable drum with a mold cavity and a confronting casting shoe for supplying molten metal, such as liquid lead, to the cavity may be used in a casting machine to continuous cast the composite strip.

A shoe for dispensing a molten metal such as lead into a mold cavity of a rotating drum to continuously cast a web of a plurality of serially connected grids or battery composite electrodes of a carbon fiber material with a cast metal conductor. The shoe may have at least one elongate orifice slot in a face confronting the drum, a molten metal supply passage communicating with the orifice slot and an excess molten metal return slot opening into the confronting face downstream of the supply slot relative generally to the direction of rotation of the drum.
