Store cells in an environment with relative humidity below 10% to prevent moisture-induced degradation. Maximum charge voltage must not exceed 4.2V ±0.05V, and operation requires a BMS with cell balancing and overvoltage protection.
- Moisture Sensitivity: Store cells in environments with relative humidity below 10% to prevent moisture-induced degradation.
- Overcharge Protection: Use only with a battery management system that provides cell balancing and overvoltage protection.
- Voltage Limit: Maximum charge voltage must not exceed 4.2V ±0.05V.
These high-nickel NCM cells are sensitive to moisture and overcharge, requiring strict environmental and electrical controls. Follow these steps to ensure safe storage and operation.
Required Equipment: Battery Management System (BMS) with cell balancing and overvoltage protection
- Store in dry environment
Store cells in an environment with relative humidity below 10% to prevent moisture-induced degradation. - Connect BMS
Connect cells to a battery management system that provides cell balancing and overvoltage protection. - Set charge voltage limit
Set the maximum charge voltage to 4.2V ±0.05V.
What is the trade-off between the 49.2Ah and 55.7Ah variants of the 46145 NCM cylindrical cell?
The 49.2Ah variant (AF46145NCM01) is optimized for high-rate applications with 3C charge and 5C discharge, making it suitable for PHEV/HEV and high-power systems. The 55.7Ah variant (AF46145NCM02) prioritizes energy density for long-range BEV, offering >2000 cycles to 70% SOH versus >1500 cycles for the high-rate version. Both share a Ni-rich cathode (Ni≥85%) and nominal voltage of 3.6V.
What are the specific system integration requirements for the 46145 high-nickel NCM cells?
These cells require a battery management system (BMS) that provides cell balancing and overvoltage protection, with a maximum charge voltage of 4.2V ±0.05V. The tabless current collector design keeps internal resistance ≤5 mΩ, enabling high pulse currents. Applications include BEV, PHEV, electric marine propulsion, eVTOL aircraft, and high-performance stationary storage.
What are the critical storage and handling requirements for the 46145 NCM cells?
High-nickel NCM cells are moisture-sensitive and must be stored in environments with <10% relative humidity. They are shipped in vacuum-sealed moisture-barrier cartons with cell dividers (2 cells per tray, 50 per master carton) and include terminal covers. Always use a BMS with cell balancing and overvoltage protection, and do not exceed the maximum charge voltage of 4.2V ±0.05V.
The ATOMFAIR 46145 series offers two high-nickel NCM cylindrical cell variants (49.2Ah high-rate and 55.7Ah high-energy) with energy densities up to 55.7Ah per cell, a tabless current collector design achieving ≤5 mΩ internal resistance, and cycle life of 1500–2000 cycles to 70% SOH, but requires strict moisture control (<10% RH) and mandatory BMS integration for overvoltage protection.
Positive
- Ultra-high energy density Ni-rich NCM: Ni≥85% cathode delivers 49.2–55.7 Ah per cell, enabling extended range in EV and eVTOL platforms.
- Tabless current collector design: Reduces internal resistance to ≤5 mΩ and maintains safe temperatures during 5C discharge pulses, improving power delivery and thermal stability.
Trade-offs
- Moisture sensitivity requires dry storage: High-nickel NCM cells must be stored in <10% RH environment to prevent degradation; moisture exposure can compromise performance and safety.
- Mandatory BMS for overvoltage protection: Maximum charge voltage is 4.2V ±0.05V; a BMS with cell balancing and overvoltage protection is required to prevent overcharge and ensure safe operation.
