Method for manufacturing doped electrode and method for manufacturing power storage device

A method for manufacturing a power storage device including an electrode cell, the method comprising:

• doping an alkali metal to an active material by bringing a dope solution in contact with a negative electrode, the dope solution flowing and comprising an alkali metal ion, the negative electrode including a negative current collector and a negative electrode active material layer, the negative electrode active material layer formed on a surface of the negative current collector, the negative electrode active material layer comprising the active material;
• wherein the alkali metal is electrically doped to the active material using a counter electrode member arranged to face the negative electrode;
• wherein the dope solution is flowed by discharging the dope solution from a nozzle located between the negative electrode and the counter electrode member;
• and
• after the alkali metal is doped to the active material, stacking the negative electrode and an electrode different from the negative electrode to form the electrode cell.

An electrode manufacturing system configured for manufacturing a doped electrode comprising an active material doped with an alkali metal by performing, on an electrode, a process of doping an alkali metal to an active material, the electrode comprising a current collector and an active material layer, the active material layer formed on a surface of the current collector and comprising the active material, the system comprising:

• a dope bath storing a dope solution comprising an alkali metal ion to carry out the process;
• a flow section that causes the dope solution stored in the dope bath to flow;
• and
• 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.
