Description

46800 High-Nickel NCM Cylindrical Battery Series

COMMERCIAL GRADE · PRODUCTION

Product Overview
The ATOMFAIR® 46800 High-Nickel NCM (LiNixCoyMn1-x-yO2) cylindrical cell series delivers industry-leading energy density in the large-format 46mm×80mm platform. Featuring a Ni-rich cathode (Ni≥85%) and advanced tabless architecture, this series is available in high-rate (AF46800NCM01, 5C discharge) and high-energy (AF46800NCM02, 27.8Ah) configurations. These cells provide exceptional power density and cycle life for next-generation electric vehicles, eVTOL, and high-performance stationary storage.

Key Features & Advantages
  • Ultra-High Energy Density: Ni-rich NCM cathode (Ni≥85%) delivers up to 27.8Ah per cell, enabling extended range in EV and eVTOL platforms.
  • Dual Performance Tiers: AF46800NCM01 (5C discharge) for high-power PHEV/HEV; AF46800NCM02 (27.8Ah) for long-range BEV.
  • Advanced Tabless Design: 46800 form factor with proprietary tabless current collector reduces internal resistance (≤4 mΩ) and improves thermal uniformity.
  • Robust Cycle Stability: Advanced electrolyte additives minimize transition metal dissolution, achieving 1500-2000 cycles to 70% SOH.
  • High Voltage Platform: 3.6V nominal voltage enables higher system voltage with fewer series connections.

APPLICATION SCOPE: Battery electric vehicles (BEV), plug-in hybrids (PHEV), eVTOL aircraft, high-performance stationary storage, and automotive-grade R&D.
PACKAGING: Vacuum-sealed moisture-barrier cartons with cell dividers (2 cells per tray, 50 cells per master carton). Terminal covers included.
IMPORTANT NOTICE: High-nickel NCM cells are sensitive to moisture and overcharge. Always store in <10% RH environment. Maximum charge voltage: 4.2V ±0.05V. Use only with battery management system (BMS) providing cell balancing and overvoltage protection.

Frequently Asked Technical Questions

What is the gravimetric energy density of AF46800NCM02?

AF46800NCM02 delivers approximately 213 Wh/kg (27.8Ah × 3.6V = 100 Wh, divided by 0.470 kg). This represents industry-leading performance for 46800 cells.

Can I charge AF46800NCM01 at 3C continuously?

Continuous 3C charging is allowed with active cooling (cell surface temperature <45°C). For maximum cycle life, we recommend 1C charging. The 3C rating applies to pulse charging (≤30 seconds) or with aggressive thermal management.

How does 46800 NCM compare to 21700 in pack-level energy density?

The 46800 format reduces inactive materials (busbars, cooling plates) by ~20% compared to 21700, improving pack-level energy density by 15-20% for the same chemistry.

What safety certifications does this series hold?

The AF46800NCM series complies with UN38.3 (transport), UL 1642 (cell safety), and IEC 62133-2:2021. Automotive-grade PPAP documentation is available for OEM customers.

What is the recommended storage voltage and temperature?

For long-term storage (>3 months), store at 30% SOC (≈3.7V) in a dry environment at 15-25°C. Refresh charge every 6 months. Avoid storage at full charge (4.2V).
