Series 9 High Nickel NCM Polycrystalline and Single Crystal Cathode Material for Lithium Ion Batteries

Product Overview

This advanced Series 9 high-nickel cathode active material represents state-of-the-art powder engineering designed to maximize gravimetric and volumetric energy density in next-generation lithium-ion energy storage systems. Available in both advanced polycrystalline agglomerate and monolithic single-crystal particle morphologies, this rich-nickel (Ni90) nickel-cobalt-manganese formulation balances high reversible capacity with outstanding structural integrity. By stabilizing the crystal lattice and strictly controlling surface chemistry, this cathode powder enables cell designers to push operating voltage limits and optimize active mass loading without compromising safety margins.

Engineered specifically for demanding tier-one battery manufacturing workflows, the material serves electric vehicle propulsion systems, high-rate electric aviation, advanced consumer electronics, and utility-scale energy storage systems. The polycrystalline variant is tailored to achieve superior compaction density and high initial discharge capacity across cylindrical, prismatic, and pouch cell configurations. Concurrently, the single-crystal variant is optimized for exceptional high-temperature calendar life, microcrack resistance under severe calendering pressures, and minimized parasitic side reactions in automotive prismatic and pouch platforms.

Manufactured under cleanroom atmospheric conditions with strict automated synthesis controls, this cathode material delivers outstanding batch-to-batch electrochemical consistency and ultra-low residual surface alkali. Cell manufacturers can depend on this powder for reliable slurry rheology, high electrode active mass fractions, and robust thermal stability under elevated operating temperatures and high depth-of-discharge cycling protocols.

Key Features

• Ultra-High Specific Capacity: Delivers exceptional reversible discharge capacities reaching 214 to 217 mAh/g at coin-cell level, significantly elevating cell-level specific energy density for long-range and weight-critical applications.
• Dual Morphological Architecture: Offered in high-tap-density polycrystalline secondary spherical clusters (D50: 12 ± 1.0 μm) for maximum volumetric loading and high-crystallinity monolithic single-crystal particles (D50: 3.5 ± 1.0 μm) for superior mechanical integrity.
• Superior First-Cycle Coulombic Efficiency: Achieves high initial coulombic efficiency ratings of 87% to 89%, reducing irreversible lithium loss during initial formation cycles and maximizing available active lithium in the closed cell system.
• Strictly Controlled Residual Alkali: Maintains both surface lithium hydroxide (OH⁻) and lithium carbonate (CO₃²⁻) levels below 0.20 wt%, preventing slurry gelling during electrode processing and suppressing high-voltage gas generation in sealed cells.
• Optimized Particle Size Distribution: Precision classification provides tightly controlled D50 particle sizing with minimal fines, ensuring uniform conductive network formation and exceptional slurry rheological stability.
• Exceptional Mechanical Robustness: Monolithic single-crystal grains withstand high-pressure roll compaction without particle fracture or surface area expansion, maintaining stable solid electrolyte interphase (SEI) film integrity over thousands of cycles.
• Elevated Compaction Density: Engineered for high calendering limits, enabling compact electrode designs that maximize volumetric capacity in space-constrained cell form factors.
• Broad Electrolyte Compatibility: Refined surface passivation chemistry minimizes transition metal dissolution and electrolyte oxidation, extending operating lifetime across standard and high-voltage commercial electrolyte systems.
