Key Features & Advantages
|
- High-Nickel NCM Cathode: Ni-rich layered oxide (Ni≥80%) delivers exceptional specific capacity (≥200 mAh/g) and reduced cobalt dependency for lower cost per kWh.
- Dual-Optimized Variants: Select between high-rate (AF46120NCM01, 39.7 Ah, 3C/5C) for power applications or high-energy (AF46120NCM02, 45 Ah, 1C/2C) for extended runtime systems.
- Robust Cycle Life & Safety: Advanced electrolyte additives and ceramic-coated separators mitigate transition metal dissolution, achieving >1500 cycles (NCM01) or >2000 cycles (NCM02) at 70% SOH.
- Low Impedance & Thermal Stability: Optimized tabless design and AI-driven electrode calendering minimize internal resistance (≤8 mΩ) and suppress hot-spot formation under high C-rates.

APPLICATION SCOPE: EV/PHEV battery packs, heavy-duty industrial equipment, grid peak-shaving prototypes, high-power two-wheeler modules, and academic R&D on Ni-rich degradation mechanisms.
PACKAGING: Vacuum-sealed moisture-barrier industrial cartons with integrated short-circuit protection (pack dimensions depend on selected variant).
IMPORTANT NOTICE: High-nickel NCM cells are moisture-sensitive. To prevent gas evolution and capacity fade, always store cells in <30% RH environment and use dry-room assembly protocols (< -40°C dew point) before first formation cycle.

Frequently Asked Technical Questions
|
What makes ATOMFAIR 46120 High-Nickel NCM cells superior for EV prototype testing?
The AF46120NCM series offers a production-ready cell with verified real-world C-rate capability. The high-rate variant (AF46120NCM01) delivers 39.7 Ah and sustains 5C discharge without thermal runaway, while the high-energy variant (AF46120NCM02) provides 45 Ah — ideal for validating range-extended electric drivetrains.
How to prevent capacity degradation in Ni-rich NCM cells?
For high-nickel cathodes, avoid deep discharge below 2.5V and never exceed 4.2V cutoff. Always pair with a BMS that implements HVS (High Voltage Spinel) protection. Store at 30% SOC in dry, cool conditions to suppress Ni4+ reactivity.
Can I mix AF46120NCM01 and AF46120NCM02 in one battery pack?
Mixing different rate-capable cells in series is not recommended due to unequal voltage drop under load. However, parallel strings of identical variants are acceptable. For multi-variant R&D, contact our engineering team for active balancing solutions.
What safety certifications does this 46120 series hold?
Each cell batch complies with UN38.3, UL 1642, and IEC 62133-2:2021. Additionally, ATOMFAIR performs internal nail penetration, overcharge, and thermal abuse tests per ISO 12405-4.
What is the expected calendar life for the AF46120NCM02?
Accelerated aging tests predict >10 years calendar life at 25°C, 60% SOC. At 45°C, retain 80% SOH after 8 years under grid storage cycling profiles. Detailed Arrhenius models are available in the product datasheet.
