Method for alkaliating electrodes

Abstract

The present invention relates to a method for lithiation of an intercalation-based anode or a non-reactive plating-capable foil or a reactive alloy capable anode, whereby utilization of said lithiated intercalation-based anode or a plating-capable foil or reactive alloy capable anode in a rechargeable battery or electrochemical cell results in an increased amount of lithium available for cycling, and an improved reversible capacity during charge and discharge.

1 . A method for lithiation of a material, preferably, in a continuous process,
 comprising the steps of:   (a) providing a material;   (b) providing a bath comprising a non-aqueous solvent and at least one dissolved lithium halide salt, wherein said bath contacts the material, preferably in a continuous process, and wherein a dry gas blanket covers said bath;   (c) providing an electrolytic field plate comprising an inert conductive material wherein said field plate establishes a field between the material and the field plate; and   (d) applying a reducing current to the material and an oxidizing current to the field plate, wherein lithium ions from the bath lithiate into the material.
