Description

46145 High-Nickel NCM Cylindrical Battery Series

COMMERCIAL GRADE · PRODUCTION

Product Overview
The ATOMFAIR® 46145 High-Nickel NCM (LiNixCoyMn1-x-yO2) cylindrical cell series delivers industry-leading energy density for high-performance electric vehicles and advanced energy storage systems. Featuring a Ni-rich cathode (Ni≥85%) and advanced low-impedance architecture, this series is available in two optimized configurations: high-rate (AF46145NCM01, 49.2Ah, 5C discharge) and high-energy (AF46145NCM02, 55.7Ah). These cells provide exceptional power density and cycle life for demanding automotive, marine, and aerospace applications.

Key Features & Advantages
  • Ultra-High Energy Density: Ni-rich NCM cathode (Ni≥85%) delivers 49.2-55.7Ah per cell, enabling extended range in EV and eVTOL platforms.
  • Dual Performance Tiers: AF46145NCM01 (3C/5C) for high-power PHEV/HEV applications; AF46145NCM02 (55.7Ah) for long-range BEV.
  • Advanced Thermal Management: Tabless current collector design reduces internal resistance (≤5 mΩ) and maintains safe temperatures during 5C pulses.
  • 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, reducing BMS complexity.

APPLICATION SCOPE: Battery electric vehicles (BEV), plug-in hybrids (PHEV), electric marine propulsion, 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) that provides cell balancing and overvoltage protection.

Frequently Asked Technical Questions

What is the gravimetric energy density of AF46145NCM02?

AF46145NCM02 delivers approximately 250 Wh/kg (55.7Ah × 3.6V = 200.5 Wh, divided by 0.802 kg). This represents industry-leading performance for 46mm cylindrical cells, suitable for long-range electric vehicles.

Can I charge AF46145NCM01 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 the cycle life of NCM compare to LFP?

NCM typically offers 1500-2000 cycles vs 3000+ for LFP, but provides 40-50% higher energy density. Choose NCM for range-critical applications (EVs, drones) and LFP for long-life stationary storage.

What safety certifications does this series hold?

The AF46145NCM series complies with UN38.3 (transport), UL 1642 (cell safety), and IEC 62133-2:2021. Automotive-grade PPAP documentation and IATF 16949 production line certification are 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) to prevent accelerated capacity fade.
