Abstract
The present invention relates to processes that may be used singly or in combination to prevent lithium (or alkali metal) plating or dendrite buildup on bare substrate areas or edges of electrode rolls during alkaliation of a battery or electrochemical cell anode composed of a conductive substrate and coatings, in which the electrode rolls may be coated on one or both sides and may have exposed substrate on edges, or on continuous or discontinuous portions of either or both substrate surfaces.
Claims31
An electrochemical process to alkaliate an anode comprising the steps of:
- a. Positioning edge guard apertures, dielectric field apertures, or shields above and below each exposed edge of the anode;
- b. Subjecting an anode to a non-aqueous electrolytic solution comprising an alkali metal salt, wherein said anode comprises a conductive substrate comprising at least one surface, an alkaliation coating on the at least one surface;
- and
- c. Applying a forward reducing current through the solution to alkaliate the anode.
