Store cells in a dry, cool environment to minimize moisture-induced corrosion and capacity loss. Avoid overcharging, over-discharging, and physical deformation to prevent thermal runaway.
- Storage Conditions: Maintain storage in a dry atmosphere with controlled temperature to prevent electrode oxidation and electrolyte decomposition.
- Handling Precautions: Ensure cells are not short-circuited or punctured during handling to avoid hazardous energy release.
Follow these steps to safely prepare the cell for first use. Each step ensures proper electrical and mechanical integrity.
Required Equipment: Compatible charger with current limiting
- Visual Inspection
Inspect the cell casing for dents, scratches, or bulging that may indicate internal damage. - Connection Setup
Connect the cell to the charger using appropriate fixtures, ensuring polarity is correct. - Initial Charge Verification
Verify that the charger applies a constant current within the cell's rated limits and monitor for abnormal heating.
What is the maximum charge voltage and storage humidity requirement for the 46145 High-Nickel NCM cylindrical battery?
The maximum charge voltage is 4.2V ±0.05V, and storage must be in an environment with less than 10% relative humidity to prevent moisture-induced degradation of the high-nickel cathode.
What are the key differences between the AF46145NCM01 and AF46145NCM02 models in terms of discharge rate and cycle life?
The AF46145NCM01 supports a 5C discharge rate with over 1500 cycles to 70% SOH, while the AF46145NCM02 supports a 2C discharge rate with over 2000 cycles to 70% SOH, reflecting a trade-off between power capability and longevity.
What BMS requirements are necessary for safe operation of these high-nickel NCM cells?
A battery management system (BMS) providing cell balancing and overvoltage protection is mandatory, as the cells are sensitive to overcharge and require precise voltage control within the 4.2V ±0.05V maximum.
The 46145 High-Nickel NCM series provides industry-leading energy density (49.2–55.7 Ah) with dual performance tiers for BEV and high-power applications, enabled by a Ni≥85% cathode and tabless architecture. Operational deployment requires strict moisture control (<10% RH) and mandatory BMS integration to mitigate overcharge risks.
Positive
- Ultra-high energy density Ni-rich cathode: Ni≥85% cathode delivers 49.2–55.7 Ah per cell, enabling extended range in EV and eVTOL platforms and reducing pack cell count.
- Tabless design for low resistance: Tabless current collector reduces internal resistance to ≤5 mΩ, maintaining safe temperatures during 5C pulses and improving power delivery.
Trade-offs
- Moisture sensitivity requires dry storage: High-nickel NCM cells must be stored in <10% relative humidity environments to prevent moisture-induced degradation, necessitating climate-controlled facilities.
- Mandatory BMS with overvoltage protection: Maximum charge voltage is 4.2V ±0.05V; the cells must be used exclusively with a BMS providing cell balancing and overvoltage protection, adding system complexity.
