Electrode assembly manufacturing method

Abstract

To provide a manufacturing method of an electrode body capable of manufacturing the electrode body with high energy efficiency.SOLUTION: A manufacturing method of an electrode body includes a drying step of drying a coated sheet 10, which is obtained by coating a collector sheet 1 having a length direction in a first direction with an electrode material, using a laser device 20, which radiates laser beams, and a pair of hot-blast devices 30, which blows a hot wind, while transferring the coated sheet in the first direction. The laser device comprises a laser head, which radiates the laser beams, and a reflector 22 including a skirt part which re-reflects the laser beams reflected from the coated sheet to the coated sheet. In the drying step, a first hot-blast device 30A which is provided at an upstream side of the laser device and a second hot-blast device 30B which is provided at a downstream side of the laser device are used as the pair of hot-blast devices, and the first hot-blast device and the second hot-blast device blow the hot wind to the side of the laser device in the first direction.SELECTED DRAWING: Figure 2
