ABSTRACT:
A method of treating a copper current collector (copper mesh and/or copper foil) for use in Li-ion and/or Li-ion polymer batteries, comprising the steps of: positioning a copper current collector within an electrolytic solution adjacent an anode plate, the electrolytic solution comprised of about 2 to about 25 grams/liter of Cu.sup.+2, and about 30 to about 100 grams/liter of H.sub.2 SO.sub.4 ; energizing the system to have a predetermined current density; maintaining the current density of the system for about 0.5 to about 3.0 minutes; and removing the copper current collector from the electrolyte solution and rinsing the same.
