1. A method for fabricating a battery electrode, the method comprising:
arranging a woven mesh planar sheet as a current collector, wherein the woven mesh planar sheet is a sheet composed of metallic strands defining a multiplicity of interstitial spaces;
cleaning the woven mesh planar sheet;
bending longitudinal edges of the woven mesh planar sheet;
applying lithium onto a first surface of the woven mesh planar sheet;
merging the lithium onto the woven mesh planar sheet such that the lithium is embedded in the interstitial spaces of the woven mesh planar sheet;
joining the lithium onto the woven mesh planar sheet;
unbending the longitudinal edges of the woven mesh planar sheet;
trimming the longitudinal edges of the woven mesh planar sheet; and
passivating the woven mesh planar sheet.
