摘要： An electrode manufacturing apparatus dopes an active material in a strip-shaped electrode precursor having a layer including the active material with alkali metal. The electrode manufacturing apparatus includes a doping bath configured to store a solution including alkali metal ions; a conveyor unit configured to convey the electrode precursor along a path passing through the doping bath; a counter electrode unit housed in the doping bath and comprising a conductive base material and an alkali metal-containing plate arranged on the conductive base material; and a connection unit configured to electrically connect the electrode precursor and the counter electrode unit. A distance between the alkali metal-containing plate and the electrode precursor becomes greater as a measurement position of the distance becomes closer to a connection position in which the electrode precursor and the connection unit connect each other.

摘要： An electrode manufacturing system includes: a doping unit; a cleaning unit: and a conveyor unit. The doping unit performs a process of doping an active material in a strip-shaped electrode with an alkali metal, the strip-shaped electrode including an active material layer formed portion in which an active material layer including the active material is formed, and an active material layer unformed portion in which the active material layer is not formed. The cleaning unit cleans the active material layer unformed portion that is adjacent to the active material layer formed portion. The conveyor unit conveys the electrode from the doping unit to the cleaning unit.

摘要： A doping system dopes an active material with an alkali metal, the active material being contained in a layer of a strip-shaped electrode. The doping system includes a doping bath, a conveyor unit, a counter electrode unit, a connection unit, and a recovery unit. The doping bath stores a solution containing alkali metal ions. The conveyor unit conveys the electrode along a path passing through the doping bath. The counter electrode unit is housed in the doping bath. The connection unit electrically connects a conveyor roller provided in the conveyor unit with the counter electrode unit. The recovery unit collects in the doping bath the solution adhered to the electrode having passed through the doping bath.

摘要： Provided is a method for manufacturing an electrode by doping an active material included a layer of an electrode precursor with alkali metal. The electrode precursor and a counter electrode member are brought into contact with a solution containing an alkali metal ion in a dope bath. The counter electrode member includes a conductive base material, an alkali metal-containing plate, and a member having an opening. The member having the opening is located between the conductive base material and the alkali metal-containing plate. The member having the opening is, for example, a resin film having an opening.

摘要： A doped electrode is manufactured by an electrode manufacturing method. The doped electrode includes an active material doped with an alkali metal. In the electrode manufacturing method, a dope solution is brought into contact with an electrode. The electrode includes a current collector and an active material layer. The active material layer is formed on a surface of the current collector and includes the active material. The dope solution includes an alkali metal ion and flows. In the electrode manufacturing method, for example, the alkali metal is electrically doped to the active material using a counter electrode member arranged to face the electrode.

摘要： The electrode manufacturing system comprises a cutting device. The cutting device cuts an electrode material along one direction of the electrode material to manufacture electrodes. The electrode material comprises first sections and a second section. The first section includes an active material doped with alkali metal, and extends in the one direction. The second section is located between two adjacent first sections of the first sections. In the second section, the active material doped with alkali metal is absent. The cutting device cuts the second section.
