Abstract
A method for manufacturing a positive electrode for a secondary battery includes unwinding a positive electrode base material, transferring the positive electrode base material to a first coating unit through a plurality of rollers, coating an insulating material at predetermined positions on opposite sides of the positive electrode base material with respect to a transfer direction of the positive electrode base material to form insulating portions, drying the insulating material to form insulating portions, coating a positive electrode slurry between the insulating portions on the opposite sides of the positive electrode base material, and drying the positive electrode slurry to form a positive electrode film formed with a positive electrode portion on the positive electrode base material.
