Abstract
A method for manufacturing a doped electrode may use an active metal layer doped with an alkali metal. A strip-shaped electrode may including an active material layer may be conveyed along a path that passes through a doping tank that stores a doping solution containing ions of an alkali metal and an aprotic organic solvent, a counter electrode unit, and a guide mechanism. In the doping tank, a distance between the electrode and the counter electrode unit may be maintained in a fixed range by the guide mechanism disposed between the electrode and the counter electrode unit. In the doping tank, the electrode and the counter electrode unit may be electrically connected via the doping solution.
