Abstract
A system configured to roll a metal into a foil. The system includes work rollers spaced apart to accommodate the metal therebetween. The work rollers are configured to press against the metal to roll the metal into the foil. A cooling subsystem is spaced apart from the work rollers on a work line configured to feed the metal to the work rollers. The cooling subsystem is configured to cool the metal as the metal moves along the work line.
Claims18
A system configured to roll a metal into a foil, the system comprising:
- work rollers spaced apart to accommodate the metal therebetween, the work rollers configured to press against the metal to roll the metal into the foil;
- and
- a cooling subsystem spaced apart from the work rollers on a work line configured to feed the metal to the work rollers, the cooling subsystem configured to cool the metal as the metal moves along the work line;
- wherein:
- the cooling subsystem includes an upper guide and a lower guide opposite to the upper guide, the upper guide and the lower guide are spaced apart to accommodate the metal therebetween;
- and
- one of the upper guide and the lower guide is configured to push the metal against the other of the upper guide and the lower guide.
A system configured to roll a metal into a foil, the system comprising:
- work rollers spaced apart to accommodate the metal therebetween, the work rollers configured to press against the metal to roll the metal into the foil;
- and
- a cooling subsystem spaced apart from the work rollers on a work line configured to feed the metal to the work rollers, the cooling subsystem including an upper guide and a lower guide on opposite sides of the work line, at least one of the upper guide and the lower guide is configured to be cooled with a coolant to cool the metal as the metal moves through the cooling subsystem;
- wherein at least one of the upper guide and the lower guide includes cooling rollers defining cooling channels configured for circulating the coolant through the cooling rollers.
A system configured to roll a metal into a foil, the system comprising:
- work rollers spaced apart to accommodate the metal therebetween, the work rollers configured to press against the metal to roll the metal into the foil;
- and
- a cooling subsystem spaced apart from the work rollers on a work line configured to feed the metal to the work rollers, the cooling subsystem including an upper guide and a lower guide on opposite sides of the work line, at least one of the upper guide and the lower guide is configured to cool the metal as the metal moves through the cooling subsystem;
- wherein the metal includes at least one of lithium, indium, tin, lead, and sodium, and the foil is configured as an active layer of a battery electrode;
- and
- wherein at least one of the upper guide and the lower guide includes a heat pump configured to cool the metal.
