METHOD OF DRYING SLURRY FOR ELECTRODE OF RECHARGEABLE BATTERY AND APPARATUS FOR THE SAME

摘要

A method and a device for drying electrode slurry for a secondary battery are provided to maintain a uniform drying process condition and prevent the occurrence of a drying process failure caused by a partial error of the device. A method for drying electrode slurry for a secondary battery comprises a step of coating a current collector with solvent-containing active material slurry, followed by heating the slurry-coated electrode current collector in a drying room to remove the solvent. Hot air is supplied to the slurry-coated electrode current collector and an infrared lamp(232) emits infrared rays from above the slurry at the same time. An indirect temperature measurement to measure the ambient temperature of the drying room and a direct temperature measurement to measure the surface temperature of the slurry applied onto the current collector are accomplished at the same time.
