This product is an NMP‑dispersed single‑walled carbon nanotube conductive slurry. It is an odorless black liquid formulated with single‑walled carbon nanotubes, dispersing agent and N‑Methyl‑2‑pyrrolidone (NMP) solvent. The slurry belongs to non‑Newtonian fluid featuring pseudoplasticity and thixotropy, designed to serve as high‑efficiency conductive additive for electrochemical systems.
