Abstract
The present invention provides an electrode running roller which causes an electrode sheet in which a current collector is coated with an electrode active material to run, wherein the running roller includes a cylindrical section, and a tapered section extending from one end portion of the cylindrical section, and the tapered section has a shape in which an outer diameter gradually decreases toward a distal end portion of the tapered section.
Claims15
An electrode running roller configured to move an electrode sheet in which a current collector is coated with an electrode active material, the electrode running roller comprising:
- a cylindrical section;
- and
- a tapered section extending from an end portion of the cylindrical section, the tapered section having a shape in which an outer diameter of the tapered section gradually decreases from the end portion of the cylindrical section toward a distal end portion of the tapered section.
A method of moving an electrode sheet with an electrode running roller, the electrode sheet including a current collector coated with an electrode active material, the method comprising:
- moving the electrode sheet with the electrode running roller, the electrode running roller having a cylindrical section and a tapered section extending from an end portion of the cylindrical section, the tapered section having a shape in which an outer diameter of the tapered section gradually decreases from the end portion of the cylindrical section toward a distal end portion of the tapered section.
