These high-nickel NCM cells are moisture-sensitive and require storage below 30% relative humidity to prevent gas evolution and capacity fade. Assembly must be performed in a dry room with dew point below -40°C before the first formation cycle.
- Moisture Sensitivity: Store cells in an environment with relative humidity below 30% to avoid moisture-induced degradation.
- Dry Room Assembly: Use dry-room protocols with dew point below -40°C prior to the initial formation cycle.
- Packaging Integrity: Maintain vacuum-sealed moisture-barrier packaging with integrated short-circuit protection until use.
Follow these steps to ensure safe handling and proper conditioning of high-nickel NCM cylindrical cells before use. Improper storage or assembly can lead to gas evolution and capacity loss.
Required Equipment: Calibrated hygrometer
- Inspect Packaging
Inspect the vacuum-sealed moisture-barrier carton for any damage or breaches before opening. - Verify Storage Conditions
Confirm that the storage environment maintains relative humidity below 30% using a calibrated hygrometer. - Transfer to Dry Room
Transfer the cells to a dry room with dew point below -40°C prior to the first formation cycle. - Maintain Short-Circuit Protection
Ensure integrated short-circuit protection remains intact during all handling and assembly steps.
What is the trade-off between the high-rate AF46120NCM01 and high-capacity AF46120NCM02 variants in terms of cycle life and discharge rate?
The high-rate variant (AF46120NCM01, 39.7 Ah) supports 3C charge/5C discharge but achieves >1500 cycles at 70% SOH, while the high-capacity variant (AF46120NCM02, 45 Ah) supports 1C/2C and achieves >2000 cycles. This reflects a direct trade-off between power capability and cycle life longevity.
What are the critical compatibility requirements for integrating 46120 NCM cells into an EV battery pack?
These cells require dry-room assembly protocols with < -40°C dew point and storage in <30% RH environment due to moisture sensitivity of the high-nickel NCM cathode (Ni≥80%). They are designed for EV/PHEV battery packs, heavy-duty industrial equipment, grid peak-shaving prototypes, and high-power two-wheeler modules, with custom form factors available upon request.
What storage and handling conditions are required to prevent degradation of high-nickel NCM cylindrical cells?
High-nickel NCM cells are moisture-sensitive; store in <30% RH environment and use dry-room assembly protocols (< -40°C dew point) before first formation cycle to prevent gas evolution and capacity fade. Packaging is vacuum-sealed moisture-barrier with integrated short-circuit protection.
Atomfair's 46120 series offers two high-nickel NCM cylindrical cell variants optimized for either high-rate or high-capacity applications, delivering >200 mAh/g specific capacity and low internal resistance ≤8 mΩ. The cells require stringent moisture control (<30% RH storage, dry-room assembly) to prevent degradation, making them suited for controlled-lab or industrial prototyping environments.
Positive
- Dual-optimized high-rate and high-energy variants: The 46120 series provides AF46120NCM01 (39.7 Ah, 3C/5C) for power-demanding applications and AF46120NCM02 (45 Ah, 1C/2C) for extended runtime, allowing flexible deployment across EV powertrain development and stationary storage R&D.
- Robust cycle life with low impedance: Advanced electrolyte additives and ceramic-coated separators enable >1500 cycles (NCM01) or >2000 cycles (NCM02) at 70% SOH, while tabless design and AI-driven calendering keep internal resistance ≤8 mΩ for thermal stability.
Trade-offs
- Moisture-sensitive handling requirements: High-nickel NCM cells require <30% RH storage and dry-room assembly (< -40°C dew point) to prevent gas evolution and capacity fade, necessitating specialized infrastructure for safe processing.
