Key Features

• Balanced Electrochemical Composition: Features a precise chemical formulation of LiNi0.5Co0.2Mn0.3O2 with a 59.2% total transition metal content (Ni+Co+Mn) and 7.1% lithium content, delivering an optimal compromise between high specific capacity, high operating voltage, and superior thermal safety.
• High Tap Density and Compactability: Delivers a minimum tap density of 2.0 g/cm³ (typical value 2.20 g/cm³ measured at 3000 taps with a 3mm amplitude), facilitating high volumetric energy density, superior electrode compaction, and high active mass loading during calender pressing.
• Controlled Particle Size Distribution: Carefully classified grain distribution with D10 ≥ 5.0 μm (typical 6.4 μm), D50 between 8.0 and 12.0 μm (typical 10.6 μm), and D90 ≤ 25.0 μm (typical 17.5 μm) enables uniform packing, tight slurry coating tolerances, and reduced risk of current collector tearing.
• Optimized Specific Surface Area: Maintained within 0.20 to 0.60 m²/g (typical 0.27 m²/g via BET measurement), reducing parasitic surface-electrolyte side reactions while providing sufficient active reaction interfaces for rapid lithium-ion diffusion.
• Ultra-Low Trace Impurities: Controlled via high-precision inductively coupled plasma (ICP) testing to ensure minimal magnetic and metallic contaminants (Fe ≤ 0.0010%, Cu ≤ 0.0050%, Ca ≤ 0.0200%, Na ≤ 0.0300%), significantly lowering cell self-discharge rates and eliminating internal short-circuit risks.
• Low Residual Moisture and Controlled Alkalinity: Stringently dried to achieve ≤ 0.10% moisture content (typical 0.07%) and a stable pH ≤ 11.6 (typical 11.35), preventing slurry gelation during NMP/PVDF mixing and preserving long-term binder network integrity.
• Outstanding Specific Discharge Capacity: Delivers a typical discharge capacity of 160.1 mAh/g at 0.5C and 155.2 mAh/g at 1C within a 2.75V to 4.3V operating window against Li metal, ensuring reliable rate performance.
• High Initial Coulombic Efficiency: Achieves a typical initial efficiency of 84.5% (standard ≥ 83%) during 0.5C coin cell cycling (2.75V–4.3V vs. Li), maximizing available energy output and minimizing irreversible lithium consumption in initial formation cycles.
