Title:
ELECTRODE MANUFACTURING DEVICE AND ELECTRODE MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2020/084949
Kind Code:
A1
Abstract:
This electrode manufacturing device manufactures a strip-shaped doped electrode by doping, with alkali metal, an active material in a strip-shaped electrode precursor having a layer that contains the active material. The electrode manufacturing device is provided with: a sensor for detecting a mark that the electrode precursor has; at least one doping tank housing a solution that contains alkali metal ions; a conveyance unit configured so as to convey the electrode precursor along a route passing through the inside of the doping tank; a counter electrode unit housed in the doping tank; a connection unit for electrically connecting the electrode precursor and the counter electrode unit; a power source configured so as to pass a current to the counter electrode unit via the connection unit; and a power source control unit configured so as to control the power source on the basis of a detection result of the sensor.
