NFMS Nickel-iron Manganese Acid Sodium Laminate Oxide

Overview

NFMS Cathode Active Material (NaNi₀.₃₃Fe₀.₃₃Mn₀.₃₃O₂) is a layered transition-metal oxide designed for next-generation sodium-ion battery (SIB) research. By combining nickel, iron, and manganese within a sodium lamellar oxide framework, this material offers a balanced trade-off between energy density, structural stability, and cost-effective elemental composition.

Working Principle

During electrochemical cycling, sodium ions reversibly intercalate and de-intercalate within the layered oxide structure while charge compensation occurs via the redox activity of Ni, Fe, and Mn. The multi-metal system helps stabilise phase transitions during cycling, supporting improved capacity retention and rate capability compared with single-metal sodium cathodes.

Key Material Characteristics

• Typical specific capacity: ~127 mAh g⁻¹
• Optimised particle size distribution: D₅₀ ≈ 7–8 µm
• Controlled surface area: ~0.7 m² g⁻¹
• Low residual moisture: <500 ppm
• High tap density: ~1.34 g cm⁻³
• Alkaline stability: pH <13

These properties enable reliable electrode processing, consistent slurry behaviour, and reproducible electrochemical performance in laboratory-scale cells.

Compatibility & Applications

NFMS cathode powder is compatible with standard coin cells, pouch cells, and laboratory sodium-ion battery test cells. It is widely used for:

• Sodium-ion battery performance benchmarking
• Charge–discharge and rate capability studies
• Structural and phase analysis (XRD, operando techniques)
• Electrochemical testing using potentiostats and battery cyclers
