1. A method of fabricating a stand-alone active metal negative electrode that is not affixed to a positive electrode, the method comprising:
- (a) forming a glassy or amorphous protective layer on a substrate, the protective layer forming a substantially impervious layer which is conductive to ions of an active metal;
(b) depositing a first active metal layer on the protective layer; and
(c) providing a current collector on the first active metal layer to form the stand-alone active metal electrode.

Abstract
A method for fabricating an active metal electrode involves depositing lithium or other active metal electrode on a protective layer. The protective layer is a glassy or amorphous material that conducts ions of the active metal. It may be deposited on a releasable web carrier or other substrate such as polymer electrolyte layer. Lithium is then deposited on the protective layer. Finally, a current collector is attached to the lithium.
