[Analysis Case] Component Evaluation of Positive and Negative Electrode Binders in Secondary Batteries

Identification of organic substances using TOF-SIMS and GS/MS.

The binder for lithium-ion secondary batteries not only serves as an adhesive between active materials but also needs to be insoluble in the electrolyte. Therefore, the selection of suitable materials for both the positive and negative electrodes is crucial. This document presents cases where the components of the binders used in each electrode sheet were identified by measuring the positive electrode binder using TOF-SIMS and the negative electrode binder using GC/MS, and then comparing the results with a materials library database.
