Title:
ELECTRODE MANUFACTURING SYSTEM AND ELECTRODE MANUFACTURING METHOD FOR ADHESION ENHANCEMENT
Document Type and Number:
WIPO Patent Application WO/2024/071949
Kind Code:
A1
Abstract:
The present invention relates to an electrode manufacturing system, an electrode manufacturing method, and an electrode manufactured thereby. The electrode manufacturing system includes a heating unit that is provided downstream of a dryer unit to heat an electrode base material at a high temperature, and the crystalline phase of a PVdF binder in the electrode base material is changed during the heating process, thus increasing the adhesion of an electrode and enabling prevention of separation of an electrode active material layer.
