Although the adhesion properties of composite electrodes are important for securing
long-term reliability and realizing high energy density of lithium secondary batteries, related
research has not been carried out extensively due to the limitation of measurement technology.
However, surface and interfacial cutting analysis system(SAICAS), which can measure the
adhesion properties while cutting and peeling a coating layer of 1~1000 μm thickness, has been
developed and applied for analyzing the adhesion properties of composite electrodes for lithium
secondary batteries. Thus, this review presents not only the principle and measurement method
of SAICAS but also comparison results between SAICAS and conventional peel test. In addition,
application examples of SAICAS are introduced in the study of electrode design optimization,
new binder derivation study, and binder distribution in composite electrode. This
suggests that SAICAS is an analytical method that can be easily applied to investigate the adhesion
properties of composite electrodes for lithium secondary batteries.
