Abstract
A time for doping an electrode material on an electrode sheet with a lithium ion can be reduced. The electrode manufacturing apparatus includes a processing chamber 200 to and from which the electrode sheet is loaded and unloaded; a rare gas supply unit 230 configured to introduce a rare gas into the processing chamber; an exhaust device 220 configured to exhaust an inside of the processing chamber to a certain vacuum level; and a lithium thermal spraying unit 210 configured to dope a carbon material C with the lithium ion by forming a lithium thin film on the carbon material of the electrode sheet W loaded into the processing chamber while melting and spraying lithium-containing powder.
