Embodiments described herein relate generally to electrochemical cells having pre-lithiated semi-solid electrodes, and particularly to semi-solid electrodes that are pre-lithiated during the mixing of the semi-solid electrode slurry such that a solid-electrolyte interface (SEI) layer is formed in the semi-solid electrode before the electrochemical cell formation. In some embodiments, a semi-solid electrode includes about 20% to about 90% by volume of an active material, about 0% to about 25% by volume of a conductive material, about 10% to about 70% by volume of a liquid electrolyte, and lithium (as lithium metal, a lithium-containing material, and/or a lithium metal equivalent) in an amount sufficient to substantially pre-lithiate the active material. The lithium metal is configured to form a solid-electrolyte interface (SEI) layer on a surface of the active material before an initial charging cycle of an electrochemical cell that includes the semi-solid electrode.

Pre-lithiation of electrode materials in a semi-solid electrode

Embodiments described herein relate generally to methods for the remediation of electrochemical cell electrodes. In some embodiments, a method includes obtaining an electrode material. At least a portion of the electrode material is rinsed to remove a residue therefrom. The electrode material is separated into constituents for reuse.

Methods for electrochemical cell remediation

Embodiments described herein relate generally to electrodes for electrochemical cells, the electrodes including an electrode material disposed on a current collector. In some embodiments, an electrode includes an edge protection barrier member on a perimeter of a surface of the current collector. The barrier member forms a wall along the main edge(s) of the current collector, defining an inner region bounded by the barrier member and the top surface of the current collector, and the electrode material occupies the inner region.
