Abstract
A system for manufacturing a positive electrode for a secondary battery includes an unwinder wound with a positive electrode base material, a first coating unit for coating an insulating material at predetermined positions about widthwise edges of the base material with respect to a transfer direction of the base material supplied from the unwinder, a first drying furnace for drying the insulating material by heating the base material coated with the insulating material, a second coating unit for coating a positive electrode slurry on the base material supplied from the first drying furnace in a region between the insulating material formed at both sides of the base material, and a second drying furnace for heating and drying the base material coated with the insulating material and the positive electrode slurry.
