Method for the extraction of lithium from an electric battery comprising solid metallic lithium

Abstract

A method for the extraction of lithium from an assembly of at least one cell of an electric battery including solid metallic lithium, such as a Lithium-Metal-Polymer battery, the method having an extraction phase including the following steps: positioning the assembly in an orientation in which a first edge of the assembly from which extend(s) one or more negative electrode or electrodes is located below a second edge of the assembly, opposite the first edge, and from which extend(s) one or more positive electrode or electrodes; and heating the assembly to a treatment temperature greater than or equal to the melting temperature of the solid metallic lithium. An installation implementing such a method is also provided.
