DRYING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/032250
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a drying system which can reduce energy consumption more than conventional systems in a drying step for a coating film in the manufacturing process of a lithium-ion battery. This drying system, which is for drying a coating film made of a slurry of an electrode material formed on a base material in the manufacturing process of a lithium-ion battery, comprises: a gas supply unit that supplies gas to be used in order to dry the coating film; a drying unit that heats the gas supplied by the gas supply unit and heats the coating film formed on the base material with the heated gas to dry the coating film; a gas discharge unit that discharges a portion of the gas from the drying unit; a solvent recovery unit that cools and recovers a solvent vaporized by the coating film being heated by the drying unit; a circulation path that circulates the gas between the drying unit and the solvent recovery unit; and a first heat exchange unit that performs heat exchange between the gas heading from the drying unit to the solvent recovery unit through the circulation path, and the gas heading from the solvent recovery unit to the drying unit through the circulation path.
