Abstract
The present invention is directed to a method for pre-lithiation of negative electrodes during lithium loaded electrode manufacturing for use in lithium-ion capacitors. There is provided a system and method of manufacture of LIC electrodes using thin lithium film having holes therein, and in particular, to the process of manufacturing lithium loaded negative electrodes for lithium-ion capacitors by pre-lithiating electrodes with thin lithium metal films, wherein the thin lithium metal films include holes therein, and the lithium loaded negative electrodes are manufactured using a roll-to-roll lamination manufacturing process.
