Product Overview
This high-purity sodium iron manganese oxide powder is an advanced P2-type layered cathode material engineered specifically for next-generation sodium-ion energy storage systems. Formulated with a precise stoichiometric composition of Na2/3[Fe1/2Mn1/2]O2 and a guaranteed minimum purity of 99.9%, the material delivers a compelling balance of high reversible specific capacity, abundant earth-friendly constituents, and cost-effective electrochemical performance. It addresses the growing market demand for cobalt- and nickel-free battery chemistries without compromising voltage stability or energy density.
Designed for laboratory research, prototyping, and pilot-scale cell manufacturing, the powder serves academic institutions, battery R&D centers, and commercial energy storage developers. The material is optimized for integration into standard non-aqueous cathode processing workflows, including slurry casting, doctor-blade coating, and calendering for coin cells, pouch cells, and cylindrical formats. Its controlled primary particle size ensures rapid sodium-ion transport across electrode architectures.
Rigorous quality controls guarantee ultra-low transition-metal and alkali-metal impurity levels, protecting against parasitic side reactions, electrolyte decomposition, and premature cell degradation. With an operational voltage window of 1.5 V to 4.0 V and a proven 0.1C specific capacity reaching 180 mAh/g, this cathode material empowers electrochemical engineers to build robust, high-voltage sodium-ion cells capable of consistent cycling under demanding operational environments.
Key Features
- High-Purity P2-Type Layered Structure: Synthesized to maintain a stable P2 crystallographic phase that facilitates open prismatic sodium-ion diffusion pathways, delivering rapid ion intercalation and superior high-rate discharge performance.
- Cobalt-Free and Nickel-Free Composition: Leverages earth-abundant iron and manganese active centers to eliminate dependency on volatile supply chains while maintaining high nominal redox potential and attractive commercial economics.
- Sub-Micron to Fine Primary Particle Architecture: Engineered with a primary particle size of ≤3 µm, maximizing active surface contact with the conductive network, minimizing solid-state diffusion paths, and enhancing rate capability.
- Exceptional 3N Chemical Purity: Guaranteed purity of ≥99.9% with tightly controlled trace contaminants minimizes internal micro-shorting risks, suppress electrolyte oxidation, and preserve interfacial stability.
- Controlled Stoichiometric Accuracy: Exact molar ratio of Na:Fe:Mn:O at 2/3:1/2:1/2:2 prevents unreacted precursor phases, eliminates inactive rock-salt domains, and optimizes theoretical electrochemical utilization.
- High Initial Specific Discharge Capacity: Delivers up to 180 mAh/g reversible capacity at 0.1C within a practical 1.5 V to 4.0 V operational window, offering high specific energy density for next-generation cathode systems.
- Reliable Cycling Stability: Demonstrates 70% capacity retention over 20 cycles in initial half-cell evaluation, providing a solid baseline for structural stabilization, electrolyte optimization, and coating engineering.
- Streamlined Slurry Processability: Uniform black powder morphology disperses evenly in NMP/PVDF and aqueous binder systems, ensuring high mechanical adhesion, smooth coated surfaces, and low electrode tortuosity.
