Abstract Scope It is essential to use single walled carbon nanotubes (SWCNT) as a conductive material in order to alleviate the volume expansion of silicon-based anode material and obtain better capacity retention characteristics. Even if the solid content of the SWCNT conductive dispersion is the same, the viscosity, homogeneity, and stability of the dispersion vary depending on the degree of dispersion. Therefore a reference material (RM) whose characteristics are verified by securing dispersibility by content is required for its quality control. In this study, we developed three types of RM by SWCNT content: 0.4 wt% (100~300 cP), 0.8 wt% (1000~1500 cP), and 1.0 wt% (2000~2500 cP). Dispersibility test method and technology that have metrological traceability and reproducibility was developed, standardized, and applied to the RM production system, and homogeneity within 5% of the relative standard deviation and long-term stability of more than 6 months were secured.
