This lithium cobalt oxide cathode powder is engineered for high-voltage operation up to 4.55V cutoff. Exceeding this voltage limit may cause irreversible structural degradation and capacity loss.
- Voltage Cutoff Limit: Operate the material within a maximum voltage cutoff of 4.55V to avoid detrimental phase transitions and ensure cycle stability.
How does the high tap density of 2.09 g/cm³ impact the achievable rate performance for this LCO cathode powder?
The high tap density of 2.09 g/cm³ enables dense electrode compactions without sacrificing rate performance because the single-crystal-like small particle architecture (D50 6.4 μm) maintains rapid lithium transport kinetics. This is confirmed by the 3C discharge capacity of 173.3 mAh/g, which retains 95.8% of the 0.2C baseline capacity of 180.9 mAh/g at a 3.0–4.45V cutoff.
What slurry pH and residual alkali levels must be accounted for when processing this high-voltage LCO powder into electrode coatings?
The slurry process pH is below 11.0 with an actual baseline of 10.3, and residual soluble surface alkali levels are extremely low: Li2CO3 at 0.017% and LiOH at 0.002%. These values are far below typical industry thresholds, minimizing gelation and coating defects, and allowing direct use with standard PVDF binder in NMP-based slurry formulations without additional neutralization steps.
What moisture control measures are required to prevent degradation of this high-voltage LCO powder during handling and storage?
The as-received moisture content is only 83 ppm, well below the 300 ppm specification ceiling, so the powder must be stored in a dry, inert atmosphere (e.g., glovebox or dry room) to prevent moisture uptake. Exposure to ambient humidity could raise surface alkali levels and trigger parasitic reactions at 4.55V, compromising cycle life and capacity retention.
The ATOMFAIR 4.55V LCO powder delivers a specific capacity of 180.9 mAh/g at 0.2C with 96.0% first-cycle efficiency and maintains 95.8% capacity at 3C rate, but requires moisture-controlled storage (≤300 ppm H2O) and compatible high-voltage electrolyte systems to realize its full 4.55V operational ceiling.
Positive
- High-voltage capacity without phase collapse: Achieves 180.9 mAh/g at 0.2C under a 4.55V cutoff while suppressing lattice degradation, enabling higher energy density in dense electrode compactions.
- Superior high-rate discharge retention: Delivers 173.3 mAh/g at 3C rate with 95.8% capacity retention relative to 0.2C, demonstrating fast lithium transport kinetics suited for rapid charging validation.
Trade-offs
- Moisture-sensitive storage required: Maximum moisture tolerance of 300 ppm H2O is specified (actual 83 ppm), necessating dry-room or desiccated storage to prevent surface degradation and slurry issues.
- Requires high-voltage electrolyte compatibility: The 4.55V cutoff demands electrolytes stable against oxidative decomposition at elevated potentials; standard LCO electrolytes may fail, requiring specialized formulations for cell integration.
