A method of making a combined sinter-ready silver film and carrier (1) comprises the steps of: a) creating a carrier (2) comprising designed openings (5); b) casting a silver film layer (7) into the designed openings (5), for example casting a silver paste; and c) drying the carrier (2) and silver film layer (7) to form the combined sinter-ready silver film and carrier (1). The carrier (2) may comprise a plastic carrier, which may be created by permanently bonding two plastic films, using a plasma bonding process or using a temperature stable glue. The carrier (2) may comprise a stencil layer (3) and a backing layer (4). The stencil layer (3) may define the designed openings (5). The backing layer (4) may be configured for sealing a bottom of the designed openings (5), wherein at the start of step b), a top of the designed openings (5) may be open for receiving the cast silver film layer (7).

A machine and process for making a composite battery electrode with a conductive lead cast ribbon extending along and attached to a portion of a carbon fiber material. A lead ribbon may be continuously cast along a longitudinally elongate strip of carbon fiber material. The ribbon may be cast along an edge or edges of a longitudinally elongate strip of carbon fiber material.

A shoe for dispensing a molten metal such as lead into a mold cavity of a rotating dmm 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 Norifice 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 dmm.

A lead delivery apparatus for a cast on strap machine is arranged to deliver a predetermined volume of molten lead to a mould. The apparatus includes a first needle valve, a second needle valve, and a housing. The housing has a reservoir including an inlet and an outlet. The reservoir inlet is in fluid communication with a molten lead supply. The reservoir is supplied with molten lead during use such that the molten lead in the reservoir is maintained at a constant height.
