TXBN‑04/04H NMP‑based SWCNT Conductive Slurry

TXBN‑04/04H NMP‑based SWCNT Conductive Slurry

Product Introduction

Product Overview

TXBN‑04/04H is an odorless black liquid conductive slurry with NMP as solvent system. It contains 0.40 wt.% single‑walled carbon nanotubes and 0.40 wt.% dispersing agent, total solid content reaches 0.848%. This product belongs to non‑Newtonian fluid with both pseudoplastic and thixotropic rheological properties. Strict impurity control is achieved via ICP‑AES testing. Shelf‑life is 6 months from production date. It is developed primarily as conductive additive for lithium‑ion battery electrodes.

Product Advantages

  1. Low‑impurity formulation: Strictly controlled magnetic and metallic impurities, effectively reducing risks of battery self‑discharge and short‑circuit.
  2. Good dispersion stability: Stable optical density indicates uniform SWCNT dispersion, no severe agglomeration in slurry system.
  3. Appropriate rheological property: Pseudoplastic‑thixotropic non‑Newtonian fluid, matches battery‑grade slurry mixing & coating manufacturing processes.
  4. Low‑moisture performance: Moisture value 302 ppm far below 800 ppm specification limit, minimizes hydrolysis risk for lithium‑ion battery systems.
  5. Ready‑to‑use liquid form: Pre‑dispersed NMP‑based slurry, saves powder dispersion labor and avoids dust pollution on production site.
  6. Batch traceable quality: Each lot is fully inspected with standardized test methods for consistent batch‑to‑batch performance.

Product Functions

  1. Construct continuous 3‑dimensional conductive network inside battery electrodes at low addition dosage.
  2. Reduce internal resistance of electrodes, improve rate capability and cycling performance of lithium‑ion cells.
  3. Comply with NMP‑based positive‑electrode slurry system, compatible with PVDF binder formula.
  4. Optimize electrode conductivity without occupying large volume fraction of active material.

Application Scenarios

  1. Conductive additive for lithium‑ion battery cathode and anode electrodes.
  2. NMP‑compatible electrode slurry formulation for power batteries, energy‑storage batteries and consumer‑type lithium‑ion cells.
  3. Other energy‑storage devices requiring NMP‑system SWCNT conductive dispersion.

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.
