Abstract
Disclosed herein is a method of manufacturing an electrode for a rechargeable battery. The method comprises: a preparation process for preparing a workpiece on which a slurry containing a negative electrode active material is applied to at least one surface of a negative electrode current collector; and a drying process for heating and drying the slurry by irradiating a side of the slurry of the workpiece with light having a wavelength range in which light absorption in the slurry is equal to or greater than 60%.
Claims15
A method of manufacturing an electrode for a rechargeable battery, comprising:
- a preparation process for preparing a workpiece on which a slurry containing a negative electrode active material is applied to at least one surface of a negative electrode current collector;
- and
- a drying process for heating and drying the slurry by irradiating a side of the slurry of the workpiece with light having a wavelength range in which light absorption in the slurry is equal to or greater than 60%.
A drying apparatus for drying a workpiece on which a slurry containing an electrode active material is applied to at least one surface of an electrode current collector, comprising:
- a light source unit;
- a conveyance mechanism configured to convey the workpiece;
- and
- a controller unit,
- the light source unit including an LED element configured to emit light having a peak wavelength between 320 nm and 450 nm, and being arranged at a position to irradiate a side of the slurry of the workpiece with the light, and
- the controller unit controlling at least one of the light source unit and the conveyance mechanism to scan or sequentially move the workpiece and the light source unit relative to each other, and controlling the light source unit to irradiate the side of the slurry of the workpiece with the light to heat and dry the slurry.
