1. An electrode manufacturing method for manufacturing a doped electrode comprising an active material doped with an alkali metal, the method comprising:
doping an alkali metal to an active material in a state that a dope solution is in contact with an electrode, the dope solution flowing and comprising an alkali metal ion,
wherein the electrode comprises a current collector and an active material layer, and
wherein the active material layer is formed on a surface of the current collector and comprises the active material;
wherein the alkali metal is electrically doped to the active material using a counter electrode member arranged to face the electrode, and
wherein the dope solution is flowed by discharging the dope solution from a nozzle located between the electrode and the counter electrode member.
