TXBH‑04 Water‑based SWCNT Conductive Slurry

TXBH‑04 Water‑based SWCNT Conductive Slurry

TXBH‑04 Water‑based SWCNT Conductive Slurry

Product Introduction

TXBH‑04 is deionized‑water dispersed single‑walled carbon nanotube conductive slurry, an odorless black liquid compounded with single‑walled carbon nanotubes, dispersing agent and deionized water. It belongs to non‑Newtonian fluid with pseudoplasticity and thixotropy, specially developed as water‑system conductive additive for lithium‑ion batteries. Shelf‑life reaches 12 months under proper storage.

Product Advantages

  1. Water‑based solvent system, environmentally‑friendly, compatible with aqueous electrode formulation
  2. Low magnetic and metal impurities, reduce battery side‑reaction risks
  3. Stable solid‑content and uniform nanotube dispersion validated by optical density test
  4. Moderate dynamic viscosity, easy for slurry mixing and manufacturing operation
  5. Stable pH value within 6.0‑8.0, good system compatibility for water‑based battery electrodes
  6. Long shelf life of 12 months under specified storage condition

Product Functions

  1. Build continuous conductive network inside water‑system electrode sheets
  2. Lower internal resistance of lithium‑ion battery electrodes
  3. Improve electron transmission efficiency of active materials
  4. Promote rate capability and cycling performance of lithium‑ion batteries

Product Application Scenarios

  • Conductive additive for water‑process lithium‑ion battery electrodes
  • Suitable for lithium‑ion battery formulations adopting aqueous slurry system

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.
