APPARATUS AND METHOD FOR MANUFACTURING SECONDARY BATTERY ELECTRODE PLATES AND ROLLER USED THEREFOR

An apparatus for manufacturing secondary battery electrode plates includes: a coating unit configured to coat an electrode material slurry on a substrate; a rolling unit configured to roll the coated electrode plate; a slitting unit configured to slit the rolled electrode plate in a moving direction of the rolled electrode plate; and a transfer unit comprising a roller (171) in contact with one of the coated electrode plate, the rolled electrode plate, and the slit electrode plate (80) to transfer the corresponding electrode plate. The roller (171) has a first diameter part (191) having a first diameter, a second diameter part (192) having a smaller diameter than the first diameter part (191), and an inclined part (193) extending between the first diameter part (191) and the second diameter part.
