I. Conductive Slurry Production Line Solutions

1. One Line Covering Both SWCNT and MWCNT Conductive Additives

Carbon nanotube conductive additives — single-wall (SWCNT) and multi-wall (MWCNT) — are replacing carbon black in lithium-ion battery electrodes because a small addition builds a continuous conductive network at much lower loading, freeing up space for active material and improving fast-charge performance.

SWCNT is typically used at 0.05-0.3wt% for its high aspect ratio and superior long-range conductivity, while MWCNT is used at slightly higher loading for cost-sensitive cathode and anode formulations. Both require thorough dispersion to avoid agglomeration, which is where the production line design becomes critical.

2. Full-Process Equipment, From Feeding to Finished Slurry

Boyee supplies complete conductive slurry production lines from raw material feeding through to finished, coating-ready slurry: automated powder/slurry feeding and metering with precise ratio control against solvent and binder; high-speed pre-dispersion mixing to break down initial CNT bundles; nano bead mill fine dispersion using Boyee's ceramic bead mills (BYZr Ceramic Turbo Bead Mill, NMM series) to separate CNT bundles without excessive tube breakage; online viscosity and particle size monitoring for closed-loop batch consistency; and vacuum degassing and filtration before packaging or direct piping to the coating line.

3. Validated From Pilot Scale to Mass Production

Line throughput scales from lab/pilot (liter-scale) to full production, with the same core dispersion technology carried across scales so process parameters validated in pilot runs transfer directly to mass production.

For producers standardizing on single-wall CNT specifically, see Boyee's SWCNT Slurry Preparation Line , which applies a shear profile tuned to SWCNT's longer, more fragile tube structure and can integrate directly with our FCCVD growth system for producers synthesizing SWCNT on-site.
