IEC TS 62607-4-11:2026

IEC TS 62607-4-11:2026, which is a Technical Specification, specifies the dispersion stability by using the zeta potential (?) method for nano-carbon materials for lithium ion capacitors. This document describes not only the dispersion stability of nano-carbon materials but also the effect of different surfactants as well as the evaluation method for testing long-term dispersion stability using the zeta potential (?). This document describes:
• Dispersion stability of nano-carbon materials using zeta potential (?) for electrochemical capacitors using carbon nanomaterials as electrodes
• Effect of different surfactants
• Evaluation of long-term dispersion stability using the zeta potential (?) method
