Ronbay Skyland LMFP73 Cathode Material 1kg

Name: Ronbay Skyland LMFP73 Cathode Material

Material Type: Lithium Manganese Iron Phosphate (LMFP) Cathode Material (Mn / Fe ≈ 7 : 3 by mole)

Product Code: LMFP73

Brand: Skyland (subsidiary of Ronbay)

Product Introduction:

The Ronbay Skyland LMFP73 Cathode Material is a manganese-rich lithium manganese iron phosphate (LMFP) cathode powder with a Mn / Fe molar ratio of approximately 7 : 3. The elevated manganese content shifts a greater fraction of capacity onto the higher-voltage Mn²⁺/Mn³⁺ redox plateau (≈ 4.0 V vs Li/Li⁺), targeting higher gravimetric energy density than conventional LFP while preserving the olivine-type structural and thermal stability characteristic of phosphate cathodes. The Skyland LMFP73 (Product Code: LMFP73) is suitable for high-energy lithium-ion cell development and is well-matched to research and small-batch production of cells where energy density and intrinsic phosphate safety are both required.

Key Features:

Manganese-rich LMFP chemistry (Mn:Fe ≈ 7:3) — higher voltage plateau than LFP and LMFP64
High first-cycle efficiency 95.54% at 0.1C, 2.0–4.3 V
Specific capacity 145.68 mAh/g at 0.1C, 2.0–4.3 V
Fine particle size distribution — D10 0.29 μm / D50 1.06 μm / D90 14.75 μm, well-suited to slurry processing
Tap density 0.89 g/cm³ and S.S.A 15.51 m²/g — typical of carbon-coated nano-structured LMFP
Carbon coating (1.48 wt% C) — supports electronic conductivity and rate performance
Powder resistivity 46.15 Ω·cm at 30 MPa compaction — characterized for slurry and electrode design
Grey-black powder, uniform color, no agglomeration, easy to handle and process

Application Areas:

Lithium-ion battery cathode for high-energy LMFP applications
Manganese-rich LMFP cathode research targeting higher voltage plateau than LFP
Coin-cell, pouch-cell, and prismatic-cell laboratory cell development
Cathode-slurry coating research with fine-particle carbon-coated LMFP powder
Electrode formulation studies on LMFP / LFP / NCM blended cathode systems
Materials science research on Mn-Fe ratio optimization in olivine-type cathodes

Recommended Handling:

LMFP73 should be handled in a dry environment to minimize moisture pickup. Although LMFP is significantly less moisture-sensitive than high-nickel NCM, prolonged exposure to humid air can still affect slurry properties and electrochemical performance. Store in a sealed container in a cool, dry place. For slurry preparation, use appropriate solvent (NMP for PVDF binder systems, or water-based binder systems for aqueous processing) 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). Note: the elevated manganese content of LMFP73 places greater proportional capacity on the high-voltage Mn²⁺/Mn³⁺ plateau — electrolyte formulations and upper-cutoff voltage should be selected accordingly for the target cell architecture.

Packaging & Storage:

Standard packaging is in sealed aluminum-foil bags wrapped with stretch film 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 bag promptly. For best results, store under sealed, dry conditions and use within the manufacturer-specified shelf life.

Safety:

For research and industrial use only. Wear appropriate PPE (chemical-resistant gloves, safety glasses, lab coat, dust mask or respirator) when handling LMFP73 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. LMFP contains manganese, iron, and lithium phosphate compounds — handle and dispose of in accordance with local environmental and occupational health regulations. Compared with NCM-class cathodes, LMFP has excellent intrinsic thermal stability and does not release oxygen under typical thermal abuse conditions, contributing to safer cell behavior. 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 LMFP electrode protocols.
