Laser drying device

Abstract

A laser drying device for drying an electrode composite material layer, the laser drying device including a laser light source, a furnace body, and a conveying path, in which the electrode composite material layer is conveyed through the furnace body by the conveying path, the electrode composite material layer is irradiated by laser light from the laser light source, through a laser-transparent protective plate of the furnace body, so as to heat the electrode composite material layer such that the electrode composite material layer is dried, the laser-transparent protective plate is fashioned by disposing a plurality of protective plate pieces in a planar direction, and a boundary line in the planar direction between two protective plate pieces that are adjacent to each other is not parallel to a conveying direction of the electrode composite material layer.
