Zhenhua E-Chem Single-Crystal NCM523 Cathode Material 1kg

Name: Zhenhua E-Chem Single-Crystal NCM523 Cathode

Material Type: Single-Crystal NCM523 Ternary Cathode Material (Ni / Co / Mn ≈ 5 : 2 : 3 by mole)

Product Code: ZH5000BDH

Brand: Zhenhua E-Chem

Product Introduction:

The Zhenhua E-Chem Single-Crystal NCM523 Cathode is a high-performance lithium-ion battery cathode material based on the NCM523 ternary chemistry (Ni : Co : Mn ≈ 50.25 : 20.13 : 29.62 mol%), prepared in single-crystal morphology. Compared to conventional polycrystalline NCM, single-crystal NCM offers improved structural integrity under high-voltage cycling, reduced particle cracking during calendering and long-term cycling, and lower side reactions with electrolyte. The Zhenhua E-Chem NCM523 (model ZH5000BDH) is suitable for high-voltage 4.35 V applications and is well-matched to research and small-batch production of lithium-ion cells targeting balanced energy density, cost, and cycle life.

Key Features:

Single-crystal morphology — improved mechanical robustness, reduced particle cracking during calendering and cycling
High first-cycle efficiency 87.2% in CR2430 coin cell (4.35–2.8 V)
High specific capacity 175.8 mAh/g at 4.35 V upper cutoff
Tight particle size distribution — D10 2.20 μm / D50 4.20 μm / D90 8.20 μm, well-suited to slurry processing
High tap density 1.85 g/cm³ — supports high electrode loading and energy density
Low impurity content — Fe, Na, Ca, Cu, Zn, residual Li⁺ all well below specification limits
XRD-verified NMC phase purity — matches JCPDS 52-0457 standard with no unqualified secondary phases
Dark blue powder, no agglomeration, easy to handle and process

Recommended Handling:

Single-crystal NCM523 should be handled in a dry environment (relative humidity preferably below 30%) to minimize moisture pickup and residual Li⁺ increase. Store in a sealed container in a cool, dry place away from acidic vapors and reducing atmospheres. For slurry preparation, use appropriate solvent (NMP for PVDF binder systems) and follow standard cathode-slurry formulation protocols (active material + conductive carbon + binder). Coat onto aluminum current collector using a film coater (e.g., XN-VC-300, XN-VCH-300, XN-SDC) followed by drying and calendering (e.g., XN-CRPE or XN-HRPE roller press series).

Packaging & Storage:

Standard packaging is in sealed moisture-barrier bags inside lined drums. Store in a cool, dry environment away from heat sources, direct sunlight, acidic vapors, and reducing atmospheres. Once opened, reseal the inner moisture-barrier bag promptly and store in a dry box or dry room. Avoid prolonged exposure to ambient humidity, which can increase residual Li⁺ and degrade electrochemical performance.

Safety:

For research and industrial use only. Wear appropriate PPE (chemical-resistant gloves, safety glasses, lab coat, dust mask or respirator) when handling NCM523 powder, especially during weighing, transfer, and slurry preparation. Avoid generating dust; transfer powders in a fume hood or with local exhaust ventilation. Avoid contact with skin and eyes; in case of contact, flush with water and seek medical attention. NCM523 contains nickel, cobalt, and manganese, which are regulated heavy metals — handle and dispose of in accordance with local environmental and occupational health regulations. Refer to the included Safety Data Sheet (SDS) for complete safety information.

Note: Specifications listed above are typical and for reference only. Actual electrochemical performance depends on the specific cell architecture, electrolyte formulation, binder/conductive-additive composition, coating thickness, calendering parameters, formation protocol, and testing conditions — consult published literature and our technical team for guidance on specific NCM523 electrode protocols.
