Abstract
The present invention provides an apparatus for producing lithium from an aluminum-lithium alloy scrap comprising (a) a dryer for removing moisture from solid aluminum-lithium alloy; (b) a reservoir for heating and holding molten aluminum-lithium alloy; (c) a three-layered electrolysis cell comprising a most dense lowest layer of molten aluminum-lithium alloy, a middle layer of molten salt electrolyte, and an uppermost layer of molten lithium; and (d) a reactive gas fluxing unit to remove water present in the molten salt.
