Ruijing Unveils Next-Gen 1000L Gigafactory Lithium Battery Slurry Mixing Station

As global energy storage and electric vehicle gigafactories transition toward high-nickel ternary cathodes (NMC 811 / 9.5.5) and silicon-carbon anodes, traditional planetary mixers face severe bottlenecks: metallic contamination, air entrapment micro-voids, and severe viscosity stratification. For a lithium battery slurry mixing line at this scale, the bottleneck is no longer the motor but the air that arrives with the powder.

1. Deep Vacuum Deaeration Down to -0.098 MPa

Ruijing Automation’s newly patented mechanical seal enclosure eliminates microscopic air entrapment during high-speed dispersion. Operating at vacuum levels ≤ -0.098 MPa (0.5 mbar absolute), the RJ-VPM-1000L achieves a 99.98% degassing efficiency, drastically lowering internal resistance (DCR) and boosting cycle life in lithium-ion battery cells. That stage is what decides cycle life in lithium battery slurry mixing, not the peak rpm of the disperser.

2. 5-Axis CNC Machined Helical Twist Blades

The dual planetary blades are precision milled on 5-Axis CNC centers with a strict 1.5mm to 3.0mm clearance against the inner vessel wall. This tight mechanical envelope generates immense macro-convective folding and high shear rates, homogenizing ultra-high solids content (up to 78% solid loading) within 90 minutes. Blade geometry matters just as much in lithium battery slurry mixing: at 78 percent solids the batch only moves if the macro-convective fold reaches the wall.

3. Factory Acceptance Testing (FAT) & Global Delivery

Every production cell leaves Ruijing’s Dongguan manufacturing hub only after passing 100% FAT verification, helium vacuum mass spectrometry leak checks, and 72-hour continuous temperature stability validation under simulated high-viscosity loads. The same lithium battery slurry mixing cell is then re-run at the customer's own solids loading during site acceptance.
