TXBN-04/1P NMP‑based SWCNT Conductive Slurry

TXBN-04/1P NMP‑based SWCNT Conductive Slurry

TXBN-04/1P NMP‑based SWCNT Conductive Slurry

Product Introduction

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.

Product Advantages

  1. Low metal & magnetic impurity level, minimizing side reactions inside batteries
  2. Stable solid‑content and uniform nanotube dispersion verified by optical density test
  3. Controlled viscosity range for convenient processing and slurry mixing
  4. Good thixotropic rheological property, suitable for battery manufacturing process
  5. Long valid storage period up to 6 months under proper condition

Product Functions

  1. Form continuous conductive network inside electrode sheets
  2. Reduce internal resistance of lithium‑ion battery electrodes
  3. Improve electron conduction efficiency of active materials
  4. Enhance rate performance and cycling stability of lithium‑ion batteries

Product Application Scenarios

  • Conductive additive for lithium‑ion battery electrodes
  • Suitable for various lithium‑ion battery system formulations requiring carbon‑nanotube conductive agent

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.
