Product Overview – 150L Planetary Vacuum Mixer
PPCELL’s 150L planetary vacuum mixer is a high-capacity solution for both cathode and anode slurry preparation in lithium-ion battery manufacturing. As a dedicated cathode slurry mixer, it handles NMC, LFP, and LCO formulations. As an anode slurry mixer, it processes graphite, silicon-carbon, and LTO materials. With vacuum degassing, dual planetary mixing, and a high-speed disperser, this 150L unit delivers superior uniformity and bubble-free slurry for high-volume electrode coating lines. The 150L capacity is ideal for pilot production lines and small-scale manufacturing, bridging the gap between lab units (5-50L) and full-production mixers (300-2000L).
Key Features – Planetary Vacuum Mixer for Battery Slurry
- Dual-Purpose Design: One machine for both cathode and anode slurries – versatile and cost-effective for battery production lines.
- Vacuum Degassing: Eliminates air bubbles that cause pinholes in electrode coating, ensuring bubble-free, high-quality slurry.
- High Uniformity: Planetary + disperser action ensures particle-level homogeneity for consistent electrode performance.
- Scalable: Process parameters developed on lab mixers transfer directly to this 150L unit for reliable scale-up.
- Easy Cleaning: Removable vessel and scraper blades enable fast changeover between cathode and anode production.
- Precise Temperature Control: Jacketed vessel with cooling/heating capability for optimal slurry rheology.
Cathode Slurry Mixer – Optimized for NMC, LFP & LCO
As a cathode slurry mixer, our 150L planetary vacuum mixer is engineered to handle high-density, high-viscosity cathode materials. The combination of dual planetary blades and a high-speed disperser ensures:
- Excellent wetting of active material (NMC, LFP, LCO) with binder solution
- Uniform distribution of conductive additives (carbon black, CNTs, graphene)
- Vacuum degassing – removes air bubbles that cause pinholes in cathode coating
- Controlled shear – prevents damage to fragile particle morphologies
The jacketed mixing vessel allows precise temperature control, critical for PVDF-based cathodes requiring moderate heating during mixing.
Anode Slurry Mixer – Designed for Graphite & Silicon-Carbon
As an anode slurry mixer, the same 150L planetary vacuum mixer adapts to water-based anode formulations. Features include:
- High-viscosity handling – up to 1,000,000 cP for high-solid-content graphite slurries
- Silicon-carbon compatibility – gentle mixing to avoid damaging silicon particles
- Vacuum degassing – prevents hydrogen bubble formation from water-binder reactions
- Scraper blades – prevent material buildup on the vessel wall
The stainless steel vessel is corrosion-resistant to water-based slurries and easy to clean for batch changeovers between cathode and anode production.

Frequently Asked Questions
Q1: What is the difference between a planetary mixer and a high-shear mixer for battery slurry preparation?
Planetary mixers excel at handling high-viscosity, high-solid content pastes through dual-motion mixing (orbital and rotation), ensuring uniform distribution of active materials and binders. High-shear mixers are more suited for dispersing low-to-medium viscosity fluids and achieving fine particle reduction. For battery slurry preparation, planetary mixers are preferred for their ability to handle thick, viscous cathode and anode materials.
Q2: Can this 150L planetary mixer handle both water-based anode and NMP-based cathode slurries?
Yes. The 304 stainless steel vessel and blades are compatible with both water-based and organic solvent systems. The jacketed vessel allows precise temperature control – critical for PVDF-based cathodes requiring moderate heating and water-based anodes requiring cooling.
Q3: How does the vacuum degassing function improve slurry quality?
Vacuum degassing removes entrapped air bubbles that would otherwise cause pinholes, coating defects, and poor adhesion. It also prevents solvent evaporation and allows vacuum feeding, reducing material loss and improving batch consistency. For anode slurries, vacuum degassing also prevents hydrogen bubble formation from water-binder reactions.
Q4: Is temperature control available for this 150L mixer?
Yes. The jacketed vessel supports cooling or heating via a single-layer jacket on the barrel wall and bottom. The jacket interface is G1″ with quick open joint (jacket pressure ≤0.4MPa). The customer provides the circulation system – recommended jacket water inlet temperature ≤8°C and cooling water flow rate >60L/min.
Q5: Can I scale up from this 150L mixer to larger production units?
Absolutely. PPCELL offers planetary mixers from 5L laboratory units to 100L, 300L, and 1000L production models, with similar geometry and mixing action for reliable scale-up. The 150L model serves as an ideal bridge between pilot lines and full-scale production.
Q6: What safety features are included in this mixer?
The mixer includes a comprehensive safety interlock system: emergency stop switch (immediate shutdown), over-temperature alarm and shutdown, inverter overload/overcurrent/overvoltage protection, mixing barrel lift interlock (cannot rise until in position, cannot drop until pressure is normal), and a special vacuum buffer tank design to prevent vacuum pump oil backflow into the mixing drum.
