Product Overview

This high-purity lithium manganese oxide powder represents a benchmark spinel cathode material engineered specifically for advanced lithium-ion battery research, cell prototyping, and commercial electrochemical manufacturing. Synthesized with a well-ordered three-dimensional spinel crystal structure, the material provides rapid lithium-ion insertion and extraction channels that deliver exceptional rate capability, elevated working voltage, and superior structural stability. Its optimized chemical stoichiometry and tight control over transition metal purity ensure dependable electrochemical performance across demanding laboratory and pilot-scale battery production workflows.

Designed to meet the stringent requirements of battery research laboratories, academic institutions, and industrial energy storage manufacturers, this cathode material serves as an optimal active component for coin cells, pouch cells, and cylindrical battery formats. The powder exhibits balanced particle morphology and narrow size distribution, facilitating high slurry dispersion uniformity, smooth doctor-blade coating, and robust electrode adhesion. It is widely deployed in high-power applications, hybrid electric energy storage systems, and comparative material benchmarking where thermal resilience and inherent chemical safety are paramount.

Engineered under stringent quality assurance protocols, the material exhibits minimal magnetic impurity content, low residual moisture, and strictly regulated trace element profiles. This precision manufacturing guarantees consistent batch-to-batch reproducibility, preventing micro-shorting risks and premature electrolyte degradation. Researchers and cell engineers can confidently conduct cycle life assessments, thermal abuse evaluations, and high-rate discharge experiments under extreme operating conditions, relying on the powder's robust structural integrity and predictable electrochemical profile.

Key Features

• High Specific Discharge Capacity: Delivers a typical 0.1C initial discharge capacity of 121 mAh/g (>117 mAh/g specified) within a 3.0 V to 4.3 V operating window, maximizing active energy yield during baseline cell characterization.
• Controlled Particle Size Distribution: Features a tight, monomodal particle gradation with a typical D50 of 14.305 µm, D10 of 4.897 µm, and D90 of 28.891 µm, facilitating uniform slurry rheology, high packing efficiency, and defect-free electrode cast surfaces.
• Optimized Tap Density and Compacted Density: Boasts a standard tap density of 2.0 g/cm³ (1.8–2.3 g/cm³) and achieves design electrode compacted densities of 2.70 g/cm³ (up to 2.80–2.90 g/cm³ limit), ensuring robust volumetric energy density without particle fracturing.
• Ultra-Low Trace and Magnetic Impurities: Rigorous quality control maintains magnetic contaminants below 5.4 ppm (<8 ppm specified) and iron below 20 ppm (<100 ppm specified), drastically suppressing cell self-discharge and internal micro-shorting.
• Low Residual Moisture Content: Moisture levels are maintained at a typical 400 ppm (<1000 ppm threshold), preventing hydrofluoric acid generation in non-aqueous electrolytes and preserving long-term SEI layer stability.
• Superior Thermal and Cycling Resilience: Maintains >75% full-cell capacity retention over 300 cycles at 0.5C under room temperature, leveraging three-dimensional spinel framework stability to resist mechanical degradation and manganese dissolution.
• Exceptional Electrochemical Slurry Compatibility: Optimized specific surface area of 0.76 m²/g (0.4–1.0 m²/g) and an alkaline-buffered pH of 8.9 minimize binder consumption while preventing premature gelation in standard NMP/PVDF formulation matrices.
• Multi-Scale Packaging Configurations: Available in sealed, moisture-barrier packaging formats of 100 g, 500 g, and 1000 g per container to accommodate both micro-scale coin cell formulation and continuous pilot slurry mixing lines.
