Battery material production tolerates very little contamination. Iron, chromium or nickel picked up from a worn agitator, moisture absorbed during an open transfer, or a batch that was blended three minutes too long all show up later as capacity fade or inconsistent electrochemical performance.
Our equipment for this sector is configured around three constraints: contact surfaces that will not shed metal ions, a closed material path from receiving to packing, and a documented batch record. That covers cathode active materials (LFP, NMC, LCO, NCA), anode materials (graphite, silicon, LTO), electrolyte precursors and solid-state electrolyte powders.
Battery-grade processing standards
Contamination-controlled contact surfaces
SS316L contact parts with electropolished, crevice-free interiors. Shaft seals are specified for the powder rather than taken from a catalogue.
Inerting and explosion protection
Nitrogen blanketing and oxygen monitoring for solvent-wet and reactive powders, with explosion-proof motors, conductive grounding and pressure relief where the dust classification requires it.
Temperature and vacuum capability
Heating jackets for precursor drying and cooling jackets for exothermic steps. Vacuum-rated vessels where solvent removal or moisture-sensitive material is involved.
Low-attrition blending
Gentle tumbling or low-shear plough action for materials where particle morphology decides flow behaviour — spherical powders for additive manufacturing being the clearest case.
Battery material applications
Cathode active materials
LFP, NMC, LCO and NCA precursor blends with lithium source. High-intensity plough mixing for solid-state synthesis, with liquid addition controlled by spray.
Anode materials

Electrolyte precursors
LiPF6, LiFSI and solvent or additive blending. Corrosion-resistant 316L wetted parts and vacuum-capable vessels for fluoride-bearing chemistry.
Solid-state electrolytes

Frequently asked questions
Which mixer suits LFP cathode powder?
LFP blends usually go through a double cone or plough mixer in 316L with inert gas purging, followed by vacuum drying. The choice between them comes down to how fragile the powder is and whether liquid addition is part of the step.
Can the equipment connect to a glove box?
Yes — sealed discharge ports and vacuum conveying are specified for oxygen- and moisture-sensitive material, so the transfer between the mixer and the glove box stays closed.
How is contamination controlled?
Contact parts are 316L, electropolished and passivated, with crevice-free welds and seals selected for the powder. Wear parts are replaceable and documented, so a batch record can be tied to a known component condition.
