● Market size: Global magnetic-application equipment market is projected to grow at 6 % CAGR from 2023 to 2027, reaching USD 1.604 billion.
● Battery output: China alone shipped 486 GWh of power batteries in 2023.
● Trend: Ternary (NCM) and lithium-iron-phosphate (LFP) chemistries are scaling in parallel, pushing the magnetic-impurity limit to ≤ 50 ppb for Fe, Cr, Ni.
● Drivers: Energy-density gains, longer cycle life, and stricter safety mandates.
“Reducing Fe by 1 ppm extends LFP cycle life by 30–50 cycles and cuts self-discharge.”
High-intensity magnetic separator or electro-magnetic separators remove metallic contaminants before chemical purification, trimming downstream processing cost by 3–5 %.

LFP powder de-ironing | Dry Electromagnetic HCT | 1.2 T, Fe < 30 ppb | Dry powder | 30 % | Hunan Yuneng 80 kt line |
Graphite anode cleaning | High-Intensity Magnetic Separator | 0.6 T, 300 rpm pulsation | Dry powder | 20 % | BTR 50 kt line |
Spent-battery recycling | Drum magnetic separator | Co 99.6 %, Li 96.8 % recovery | Milled powder | 15 % | GEM 10 kt demo plant |
● Ultra-fine particle agglomeration → Add ultrasonic dispersion + pulsed high-gradient, boosting LFP concentrate to 93 % grade.
● High-viscosity slurry clogging → AI-controlled back-flush & flow rate, cutting downtime by 40 %.
● Dry-powder oxidation at high T → Inert N₂ atmosphere, coil ΔT < 60 °C, zero flux degradation.
● Battery-grade materials: GB/T 37207-2018 (Fe ≤ 50 ppm)
● Automotive: IATF 16949, PPAP Level 3
● Environmental: RoHS 2.0, REACH 2023, conflict-free CMRT
● Capacity: 800 units/year from tier-1 suppliers; 0.8–1.5 T matrix media in stock.
● Lead time: Standard models 4–6 weeks; modular retrofits within 48 h.
● QC: Real-time Fe monitoring via LIBS, closed-loop field adjustment.
● Added value: Magnetic-CFD coupling simulation, annual flux-decay report.
A top-5 global cell maker retrofitted its LFP line with an HCT-3000 dry separator.
● Fe dropped from 180 ppb → 25 ppb.
● 1 C cycle life improved from 2 800 → 3 500 cycles.
● Eliminated one acid-wash step, saving USD 0.32 M/year.
● Passed SOP audit in Sep 2023; continuous operation since.
