Battery electrode continuous casting drum, shoe, machine and method

A method of making a composite battery electrode, the method comprising,

• providing a drum and a casting shoe in confrontation with the drum at a first side of the drum;
• feeding a longitudinally elongate substrate to the casting shoe and the drum from a second side of the drum that is opposite the first side of the drum;
• continuous casting a ribbon of an electrically conductive metal along an edge of the longitudinally elongate substrate and with an edge spaced from the edge of the longitudinally elongate substrate and with a plurality of notches opening to the edge of the ribbon of electrically conductive metal;
• and
• severing the longitudinally elongate substrate with the ribbon into a plurality of electrodes each with a portion of the longitudinally elongate substrate with a portion of the ribbon attached thereto with a plurality of the notches therethrough.
