Sodium Nickel Iron Manganese Layered Oxide Cathode Material for Sodium Ion Batteries

Product Overview

This high-performance sodium nickel iron manganese layered oxide cathode powder represents a cutting-edge active material engineered specifically for next-generation sodium-ion battery cell development and large-scale energy storage systems. Formulated with a optimized stoichiometry of sodium, iron, manganese, and nickel elements, this system delivers an excellent balance of high specific discharge capacity (≥120.0 mAh/g target, 127 mAh/g typical at 0.1C), elevated tap density (1.34 g/cm³ typical), and low residual surface alkali content. Its optimized layered crystal architecture promotes rapid sodium-ion transport kinetics while suppressing adverse phase transformations during extended electrochemical cycling.

Designed for integration into full commercial cell manufacturing workflows, the material exhibits exceptional slurry compatibility, predictable rheological behavior, and high operational stability across coin cells, 18650 cylindrical cells, and pouch cell configurations. Target applications span stationary grid energy storage, industrial power backup modules, low-speed electric mobility units, and academic energy material R&D. The balanced chemical composition avoids reliance on scarce or costly cobalt and high nickel concentrations, ensuring an economically sustainable raw material footprint.

Manufactured under stringent quality control protocols, this unit undergoes comprehensive chemical and physical validation to guarantee consistent batch-to-batch repeatability. With rigorous monitoring of moisture content (≤500 ppm target, 432 ppm typical), particle size distribution (D50 of 7.64 µm), and surface residual carbonate/hydroxide levels, the material minimizes gelation risks during slurry preparation and ensures long-term operational integrity under demanding charge-discharge regimes and ambient moisture conditions.

Key Features

• High Gram Discharge Capacity: Delivers a certified discharge capacity of ≥120.0 mAh/g (typical value of 127 mAh/g) when tested in button half-cells within a 2.0V to 4.0V voltage window at 0.1C, offering high volumetric and gravimetric energy density.
• Superior High-Rate Discharge Kinetic Performance: Demonstrates exceptional rate capability in 18650 cylindrical test cells, retaining 106.40% capacity at 0.2C, 103.20% at 0.5C, 98.40% at 2.0C, 96.33% at 3.0C, 94.45% at 4.0C, and 91.58% at an ultra-high 5.0C discharge rate relative to the 1.0C baseline.
• Outstanding Low-Temperature Discharge Retention: Maintains high energy output under extreme environmental conditions, retaining 91.58% of room-temperature capacity at -10°C and 87.89% capacity at -20°C in full-cell testing protocols.
• Controlled Particle Morphometry & High Tap Density: Engineered with a tightly controlled particle size distribution (D10 ≥ 2.0 µm, D50 = 8.00 ± 2.00 µm, D90 ≤ 24.00 µm) and a high tap density of 1.34 g/cm³, ensuring optimal packing density during electrode calendering and pressing.
• Low Residual Surface Alkali: Features strict chemical limits on remnant sodium carbonate (Na2CO3) and sodium hydroxide (NaOH) surface species, maintaining a controlled pH of 12.82 (≤13.00 specification) to prevent slurry gelling and binder cross-linking during cathode preparation.
• Stable Slurry Processing Behavior: Formulated for high solid-content cathode slurries (up to 53% solid loading with 95.5% active material content), exhibiting controlled viscosity progression from 3540 mPa·s initially to 6820 mPa·s over 24 hours under 7% relative humidity.
• Controlled Environmental Moisture Sensitivity: Maintains capacity stability without electrochemical decay when processed under controlled atmospheric moisture conditions (7% RH for up to 5 hours), ensuring reliable pilot-scale and commercial electrode coating operations.
• Balanced Chemical Composition: Leverages abundant sodium, iron, manganese, and nickel elements (Na + Fe + Mn content of 50.50 ± 1.00 wt%) to lower overall cell manufacturing costs while ensuring environmental compliance and supply chain security.
