Product Introduction

It is an NMP‑based conductive slurry adopting single‑walled carbon nanotubes (SWCNTs) as core conductive substance. The formulation consists of 0.40 wt.% single‑walled carbon nanotubes, 2.00 wt.% dispersing agent and 97.6 wt.% NMP. Its shelf‑life is 6 months from production date. It belongs to non‑Newtonian fluid with pseudoplasticity and thixotropy, and its viscosity varies with shear rate.

Product Advantages

Low moisture content, measured at 167.7 ppm, far below 800 ppm specification limit.
Strictly‑controlled metallic and magnetic impurity level tested via ICP‑AES, lowering risks brought by metal impurities.
Stable viscosity performance within the range of 1500‑4500 cPs, actual viscosity 1567 cPs.
Qualified optical density within specification scope, showing good dispersion state of single‑walled carbon nanotubes.
Uniform black liquid appearance without peculiar odor.

Product Functions

Serve as conductive agent; single‑walled carbon nanotubes form conductive network to realize electrical conduction for battery‑related systems.

Product Application

Mainly applied for lithium‑ion batteries and other related applicable fields.

FAQ

What is the minimum order quantity (MOQ)?

Our standard MOQ is 1 kg for sample evaluation. For bulk orders, we recommend starting from 20 kg to enjoy better pricing and stable batch consistency.

Can you provide free samples for testing?

Yes, we can provide small free samples (typically 10–50 g) for initial evaluation. The courier cost is normally covered by the buyer, and it can be deducted from the first bulk order.

How should SWCNT powder be dispersed?

Due to their ultra-high aspect ratio and strong van der Waals forces, SWCNTs are much harder to disperse than conventional carbon black. We recommend using high-shear mixing, ultrasonic dispersion, or three-roll milling, combined with suitable surfactants or dispersants (such as NMP or specific polymers) to prevent agglomeration. To completely bypass the dispersion challenge, we also offer pre-dispersed water-based or NMP oil-based SWCNT conductive slurries for direct use in your production.

What is the lead time for bulk orders?

Samples can be shipped within 3–5 working days. For bulk orders, the lead time is usually 10–20 working days depending on quantity and customization requirements.

Do you support customized specifications?

Yes. We can customize purity, diameter, length, surface functionalization and packaging according to your application. Please contact us with your detailed requirements.
