A method of melt spinning lithium-metal foils includes melting lithium (Li) metal stock in an actively heated vessel to form molten Li metal. Using pressurized gas, the molten Li metal is ejected through a slotted nozzle at the base of the vessel. The ejected molten Li metal is directly impinged onto an actively cooled and spinning quench wheel or a carrier sheet that is fed across a support roller underneath the vessel. The molten Li metal is cooled and solidified on the spinning wheel/carrier sheet to form a Li-metal foil. The carrier sheet may be a polymeric carrier film or a copper current collector foil. An optional protective film may be applied onto an exposed surface of the Li-metal foil opposite the carrier sheet.
