Abstract (en)

[origin: WO2020161339A1] The invention relates to a method (300) for extracting lithium from an assembly of at least one electric battery cell comprising solid lithium metal, such as a lithium-metal-polymer battery, said method (300) comprising an extraction phase (306) comprising the following steps: - positioning (308) said assembly in an orientation in which a first edge of said assembly from which one or more negative electrodes protrude is located below a second edge of said assembly, opposite said first edge, and from which one or more positive electrodes protrude; and - heating (310) said assembly to a processing temperature higher than or equal to the melting point of solid lithium metal. The invention also relates to an installation implementing such a method.
