Measurement and Analysis of Adhesion Property of Lithium-Ion Battery Electrodes with SAICAS®

The adhesion strength of lithium-ion battery (LIB) electrodes consisting of active material, nano-sized electric conductor and polymeric binder is measured by a new analysis tool, called the Surface and Interfacial Cutting Analysis System (SAICAS^®). Compared to the conventional peel test with the same electrode, SAICAS^® gives higher adhesion strength owing to its elaborate cutting-based measurement system. In addition, the effects on adhesion property of the polymeric binder type and content, electrode density and measuring point are also investigated to determine whether SAICAS® provides reliable results. The findings confirm SAICAS^® as an effective and promising tool to measure and analyze the adhesion properties of LIB electrodes.
