Nanomanufacturing - Key control characteristics - Part 4-11: Nano-enabled energy storage - Dispersion stability of nano-carbon materials for the electrodes of lithium-ion capacitors: zeta potential method prEN IEC 62607-4-11

Scope

IEC TS 62607-4-11:2026, which is a Technical Specification, specifies the dispersion stability by using the zeta potential (ζ) 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 (ζ). This document describes:

• Dispersion stability of nano-carbon materials using zeta potential (ζ) for electrochemical capacitors using carbon nanomaterials as electrodes

• Effect of different surfactants

• Evaluation of long-term dispersion stability using the zeta potential (ζ) method
