I. SWCNT Slurry Preparation Line for Lithium Battery Conductive Additive
1. Lower Loading, Higher Conductivity — But Harder to Disperse
Single-wall carbon nanotubes deliver a conductive network at lower loading than multi-wall CNT or carbon black, which is why battery makers pushing for higher energy density and faster charge rates are moving toward SWCNT conductive additives.
The tradeoff is that SWCNT is harder to disperse — the tubes are longer, more prone to bundling, and easier to damage with excessive mechanical shear, so the production line has to balance thorough debundling against tube-length retention.
2. FCCVD Growth Integration and Shear-Tuned Dispersion
Boyee's SWCNT slurry preparation line can be paired with our FCCVD (floating catalyst CVD) SWCNT growth system for producers who want raw SWCNT synthesis and slurry preparation integrated into a single site. Continuous floating-catalyst synthesis gives consistent tube diameter and length distribution feeding into the dispersion stage; controlled pre-dispersion wets and loosens SWCNT bundles to reduce the shear load needed downstream; and the nano bead mill dispersion runs a shear profile tuned specifically for SWCNT rather than reused from MWCNT or carbon black recipes, since over-milling shortens tubes and cuts conductivity gains.
3. Turnkey Scale-Up With Consistent Process Parameters
Real-time viscosity feedback keeps the slurry within the process window electrode coating requires, and the same dispersion process validated on lab-scale equipment scales to production volume without re-optimizing shear parameters from scratch — cutting the qualification time between pilot batch and mass production.
If your formulation mixes SWCNT with MWCNT, or you need a line covering both CNT types, see Boyee's broader Conductive Slurry Production Line solutions.
