How dispersants create value in lithium-ion electrode manufacturing

Dispersants play a vital role in the production of lithium‑ion battery electrodes. Their value comes primarily from two areas: improving slurry and electrode properties, and enhancing manufacturing efficiency.

Improving Slurry and Electrode Performance

By modifying the rheological properties of the slurry, dispersants enable better dispersion of key materials such as carbon black, carbon nanotubes, and graphite. This leads to more stable and uniform formulations, whether water‑based or solvent‑based.
For Borregaard, our dedicated dispersant for lithium‑ion battery electrodes is Vanisperse LI - engineered to optimize the dispersion of conductive carbons and active materials.

Key benefits include

• Higher slurry solids content

• Controlled viscosity and improved slurry flow

• Enhanced battery capacity driven by improved electrode uniformity
  
  

Making electrode manufacturing more efficient

Because dispersants provide chemical dispersion of materials, they reduce the need for intensive mechanical mixing. This leads to significant process advantages:

 ✔ Shorter mixing time
Improved chemical dispersion minimizes reliance on long, energy‑heavy mixing protocols.

 ✔ Lower energy consumption
Reduced mechanical mixing leads directly to energy savings.

 ✔ Easier pumping and coating
Better slurry flow decreases the force needed to pump material to the slot‑die head.

 ✔ Reduced downtime
With particles properly dispersed, the risk of jamming in equipment is significantly lowered.

 ✔ Higher throughput
Less mixing time, fewer stoppages, and smoother coating operations result in increased overall electrode production capacity.
