TXBH‑08 Water‑based SWCNT Conductive Slurry

TXBH‑08 Water‑based SWCNT Conductive Slurry

TXBH‑08 Water‑based SWCNT Conductive Slurry

Product Introduction

TXBH‑08 is high‑concentration water‑based single‑walled carbon nanotube conductive slurry, odorless black liquid formulated with SWCNTs, dispersing agent and deionized water. It is a pseudoplastic & thixotropic non‑Newtonian fluid. Compared with TXBH‑04, it features higher SWCNT loading, for scenarios requiring higher carbon‑nanotube addition amount. Valid storage period is 12 months.

Product Advantages

  1. Water‑based system, environmental‑friendly, fits aqueous electrode production process
  2. Higher SWCNT concentration, less slurry addition dosage to build conductive network
  3. Controlled metal & magnetic impurity level, suppress battery internal side‑reactions
  4. Well‑dispersed nanotubes verified via optical density testing
  5. Appropriate dynamic viscosity, good processability for battery slurry preparation
  6. pH stably controlled at 6.0‑8.0; 12‑month long shelf‑life

Product Functions

  1. Form high‑efficiency interconnected conductive network in water‑based electrodes
  2. Decrease electrode internal resistance of lithium‑ion batteries
  3. Boost electron conduction of electrode active materials
  4. Enhance battery rate performance and cycle‑life performance for high‑demand formulations

Product Application Scenarios

  • High‑concentration conductive additive for water‑system lithium‑ion battery electrodes
  • Battery formulations that demand higher SWCNT content in aqueous slurry

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.
