These cells are sensitive to moisture and overcharge and require strict environmental controls. Storage must be in <10% relative humidity and charging must not exceed 4.2V per cell.
- Moisture Sensitivity: Store cells in an environment with relative humidity below 10% to prevent moisture-induced degradation.
- Overvoltage Limit: Charge cells to a maximum voltage of 4.2V ±0.05V to avoid overcharge-induced thermal runaway.
- BMS Requirement: Use only with a battery management system that provides cell balancing and overvoltage protection.
- Charge Rate Limit: Do not exceed the specified charge rate of 3C for the high-rate variant or 1C for the high-energy variant.
- Discharge Rate Limit: Do not exceed the specified discharge rate of 5C for the high-rate variant or 2C for the high-energy variant.
These cells require strict moisture and voltage control to prevent degradation and thermal runaway. Follow these steps to ensure safe operation and maximum cycle life.
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%. - Integrate with BMS
Integrate cells with a battery management system that provides cell balancing and overvoltage protection. - Charge to 4.2V
Charge cells to a maximum voltage of 4.2V ±0.05V.
How should I choose between the 49.2Ah high-rate and 55.7Ah high-energy variants of the ATOMFAIR 46145 NCM cell for my application?
Select the AF46145NCM01 (49.2 Ah) for high-power PHEV/HEV applications requiring 5C discharge and 3C charge rates with >1500 cycles to 70% SOH. Choose the AF46145NCM02 (55.7 Ah) for long-range BEV and stationary storage where energy density priority and 2C discharge with >2000 cycles are acceptable. Both variants share a 3.6V nominal voltage, Ni≥85% cathode, and tabless current collector design.
What are the critical BMS requirements and voltage constraints when integrating the 46145 High-Nickel NCM cell into a battery pack?
The cell has a maximum charge voltage of 4.2V ±0.05V and internal resistance ≤5 mΩ. A BMS with cell balancing and overvoltage protection is mandatory to prevent overcharge damage. The 3.6V nominal platform enables higher system voltage with fewer series connections, reducing BMS complexity.
What are the mandatory storage and handling precautions for these high-nickel NCM cylindrical cells to prevent capacity fade or safety incidents?
Store cells in an environment below 10% relative humidity due to moisture sensitivity of the high-nickel NCM cathode. Use only a BMS that provides cell balancing and overvoltage protection. Terminal covers are included in packaging to prevent short circuits during storage and transport.
The 46145 series high-nickel NCM cylindrical cells deliver 49.2-55.7Ah capacity with tabless design for low internal resistance, but require strict moisture control (<10% RH) and a BMS for safe operation.
Positive
- Ultra-High Energy Density: Ni-rich NCM cathode (Ni≥85%) delivers 49.2-55.7Ah per cell, enabling extended range in EV and eVTOL applications.
- Advanced Thermal Management: Tabless current collector design reduces internal resistance to ≤5 mΩ, maintaining safe temperatures during 5C discharge pulses.
Trade-offs
- Moisture Sensitivity: High-nickel NCM cells require storage in <10% relative humidity environment to prevent degradation; vacuum-sealed packaging is necessary.
- Mandatory BMS Integration: The cells require a battery management system with cell balancing and overvoltage protection, as maximum charge voltage is 4.2V ±0.05V.
