SWCNTs form a long, flexible conductive network at loadings one to two orders of magnitude below carbon black, which frees up electrode volume for active material and maintains contact as the electrode expands during cycling.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eProperty\u003c\/th\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAppearance\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eOdourless black liquid\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSWCNT content\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e0.4 wt%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWater\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e99.0 wt%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDispersing agent\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e0.6 wt%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOptical density\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e0.45–0.70 absorbance units\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eStability after centrifugation\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e0.8–1.0\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSolids content\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e0.9–1.1%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eViscosity (as received)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e800–2500 cP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003epH\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e7.0–10.0\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eShelf life\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e12 months from production date\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cem\u003eA lot-specific Certificate of Analysis is supplied with every shipment.

Stir gently before use and keep mixing conditions consistent between batches, or apparent viscosity will vary between otherwise identical slurries. Do not freeze. Add to the slurry under moderate shear rather than high-speed dispersion, which can shorten the nanotubes and undo the network advantage.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOrdering\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eContact us for pricing, pack sizes and current lead time.
