Claim 11:
12. A dry method of fabricating a dry electrode film of an energy storage device, comprising:
mixing a dry prelithiating material and a dry conductive carbon additive to form a first dry mixture wherein the dry prelithiating material does not comprise elemental lithium metal;
mixing the first dry mixture with a dry active material to form a second dry mixture;
adding a dry fibrillizable binder to the second dry mixture to form a dry electrode film mixture; and
fibrillizing the dry fibrillizable binder in the dry electrode film mixture;
wherein the dry method is a dry fabrication process substantially free of solvents
wherein the dry electrode film is free-standing, and
wherein the dry prelithiating material comprises about 0.5-10 wt. % of the dry electrode film.
