Key Advantages: Why Choose Our Microfluidic High Pressure Homogenization Technology?

This is a purely physical process with no chemical additives, no contaminants, and no solvent residue. It enables precise control over dispersion uniformity and interfacial compatibility, significantly improving ionic conductivity and stability of the electrolyte.

Compared with traditional melt blending, production efficiency is improved by over 75%. Target performance can be achieved within 55 cycles. Batch-to-batch consistency reaches over 98.5%, making it highly suitable for large-scale industrial production.

Independently developed core components ensure stable operation, reduce energy consumption by 38% versus conventional equipment, eliminate solvent residue risk, and include full technical support.

Precision microchannels generate strong shear and impact forces for uniform dispersion, ideal for hard-to-disperse systems like solid-state electrolytes, compatible with polymer, inorganic, and composite systems, boosting equipment efficiency.

Case Study: Solid-State Electrolyte

Solid-state electrolytes are key components in solid-state batteries, used in power batteries, energy storage, and consumer electronics. Ionic conductivity, component compatibility, mechanical stability, and dispersion uniformity directly affect energy density, cycle life, safety, and overall battery performance.

Limitations of Traditional Solid-State Electrolyte Preparation

Solid-state electrolytes, composed of salts, polymers, fillers, and additives, often face filler agglomeration, uneven salt dispersion, and poor polymer–filler compatibility, leading to low ionic conductivity and weak mechanical strength.

Limitations of Traditional Solid-State Electrolyte Preparation

Solid-state electrolytes, composed of salts, polymers, fillers, and additives, often face filler agglomeration, uneven salt dispersion, and poor polymer–filler compatibility, leading to low ionic conductivity and weak mechanical strength.

Conventional Melt Blending (High-Temperature Mixing)

1. Poor dispersion: only 32%–42% of inorganic fillers are evenly distributed, while most tend to agglomerate
2. High processing temperature (typically 150–200°C), which may cause decomposition of electrolyte salts and degradation of polymers, reducing performance
3. Poor compatibility between polymer and inorganic fillers, leading to phase separation and restricted ion transport with low conductivity
4. Not suitable for large-scale production; battery assembly defect rates can increase by over 28%
5. High energy consumption and consistently high production cost per unit, with significant batch-to-batch quality variation

Solution Casting Method (Dissolution and Film Formation)

1. Long processing cycle involving dissolution, stirring, casting, and drying, resulting in very low production efficiency
2. Requires large amounts of organic solvents, leaving potential residues that affect battery safety and increase environmental pressure
3. Shrinkage and cracking during drying can occur, reducing mechanical performance and shortening battery lifespan
4. Only suitable for small-scale production and unable to meet industrial mass-production demands, leading to delayed delivery

Conventional Mechanical Grinding and Mixing

1. Harsh mechanical action may damage inorganic fillers, resulting in uneven particle sizes and reduced ion transport efficiency
2. Requires multiple mixing cycles, doubling energy consumption while still failing to achieve uniform dispersion and good interfacial contact
3. Prone to introducing impurities and air bubbles, increasing the risk of internal short circuits and reducing safety
4. Significant batch variation, with ionic conductivity fluctuations exceeding ±20%, leading to potential customer complaints and even product recalls

Experimental Conclusion

  • Particle Size Refinement: The original particle size was 74 μm. After microfluidic homogenization, the overall D50 was controlled below 600 nm. The particle size was further refined from 508.36 nm at the 40th cycle to 360.57 nm at the 55th cycle, clearly demonstrating the effect of homogenization cycles on particle refinement in solid-state battery materials.
  • Dispersion Optimization: Agglomerated inorganic fillers were effectively broken down. The PDI decreased from 0.41 at the 40th cycle to 0.27 at the 55th cycle, improving dispersion uniformity by approximately 34.1%. The particle size distribution became significantly more uniform, with no obvious large particle residues (D90 reduced from 11,241 nm before optimization to 590.59 nm at the 55th cycle).
  • Performance Improvement: Based on optimized dispersion, ionic conductivity increased from 1.2 × 10⁻⁴ S/cm to 8.5 × 10⁻⁴ S/cm, while interfacial impedance between components was significantly reduced.
  • Stability Enhancement: Mechanical stability and cycling performance of the electrolyte were improved. Meanwhile, agglomeration defects were reduced, effectively lowering the defect rate in production.
