High-nickel NCM cells are sensitive to moisture and overcharge, requiring strict environmental and electrical controls. Storage humidity must be maintained below 10% RH, and charge voltage must not exceed 4.2V ±0.05V.
- Moisture Sensitivity: The cells are sensitive to moisture and must be stored in a dry environment with relative humidity below 10%.
- Overcharge Sensitivity: The cells are sensitive to overcharge and must be charged to a maximum voltage of 4.2V ±0.05V.
- BMS Requirement: The cells must be used with a battery management system that provides cell balancing and overvoltage protection.
- Storage Environment: Always store the cells in a vacuum-sealed moisture-barrier packaging or in a low-humidity environment.
This procedure outlines the critical steps for safe handling and initial setup of the 46800 series cells. Follow these steps to ensure proper storage, connection, and charging.
Required Equipment: Battery management system (BMS) with cell balancing and overvoltage protection
- Store in Dry Environment
Store the cells in an environment with relative humidity below 10% to prevent moisture degradation. - Connect to BMS
Connect the cells to a battery management system that provides cell balancing and overvoltage protection. - Charge to Voltage Limit
Charge the cells to a maximum voltage of 4.2V ±0.05V using the BMS.
What is the performance trade-off between the AF46800NCM01 and AF46800NCM02 variations of the 46800 High-Nickel NCM cylindrical battery?
The AF46800NCM01 (high-rate) delivers 5C continuous discharge with a nominal capacity of 24.6 Ah, while the AF46800NCM02 (high-energy) offers 27.8 Ah at 2C discharge. The NCM01 is optimized for power-intensive PHEV/HEV applications requiring high discharge rates, whereas the NCM02 provides greater energy density and longer cycle life (>2000 cycles to 70% SOH) for long-range BEV or stationary storage.
What are the voltage and BMS integration requirements for these 46800 NCM cells?
These cells have a nominal voltage of 3.6 V and a maximum charge voltage of 4.2 V ±0.05 V. A battery management system (BMS) with cell balancing and overvoltage protection is mandatory, as high-nickel NCM is sensitive to overcharge. The tabless architecture keeps internal resistance ≤4 mΩ, improving thermal uniformity during high-rate operation.
What storage and handling precautions are required for high-nickel NCM cells like the 46800 series?
High-nickel NCM cells are moisture-sensitive and must be stored in an environment with <10% relative humidity. They are shipped in vacuum-sealed moisture-barrier cartons with terminal covers. Always use a BMS and adhere to the 4.2 V max charge voltage; do not exceed the specified charge/discharge rates (3C/5C for NCM01, 1C/2C for NCM02) to avoid degradation.
The Atomfair 46800 series offers high-energy density Ni-rich NCM cylindrical cells with tabless architecture, available in 24.6 Ah high-rate (5C discharge) and 27.8 Ah high-energy (2C discharge) variants, requiring strict moisture control (<10% RH) and mandatory BMS integration for safe operation.
Positive
- Ultra-High Energy Density: Ni-rich NCM cathode (Ni≥85%) delivers up to 27.8 Ah per cell, enabling extended range in EV and eVTOL platforms.
- Advanced Tabless Design: Proprietary tabless current collector reduces internal resistance to ≤4 mΩ and improves thermal uniformity across the cell.
Trade-offs
- Moisture Sensitivity: High-nickel NCM cells require storage in <10% RH environment to prevent degradation; vacuum-sealed moisture-barrier packaging is essential.
- Charge Rate Limitation: Maximum charge rate is 3C for the high-rate variant and 1C for the high-energy variant, restricting fast-charging capability compared to discharge performance.
