Abstract
A method for extracting lithium from lithium-based materials to be recycled using an electrochemical reactor includes applying a voltage to a current collector at least partially disposed in an electrolyte carried by the electrochemical reactor, where the lithium-based materials including lithium to be recovered is disposed in the electrolyte and lithium ions move from the lithium-based material towards the current collector upon application of the voltage. In certain variations, the method may also include, prior to the application of the voltage, applying a current to the current collector.
