Abstract
A rotary thermal oxidizer removes polymeric and other non-metal components of exhausted batteries and cells leaving value-metals, such as cadmium, nickel, and iron behind for subsequent processing. By preheating the sweep gas to a temperature above the auto-ignition temperature of the polymers, prior to their introduction into the oxidizer, and controlling the oxygen content within the oxidizer the risks of explosion and fire associated with the pyrometallurgical recycling of the cells is substantially reduced.
