The cell must be stored in a cool, dry environment to prevent moisture ingress and thermal degradation. During operation, the cell must not be exposed to temperatures outside the specified discharge range and must be protected against overcharge, overdischarge, and physical abuse.
- Storage Environment: Store the cell in a cool, dry environment to prevent moisture ingress and thermal degradation.
- Temperature Limits: The cell must not be operated at temperatures exceeding 55°C during discharge or below -40°C during discharge, and charging must only occur between -10°C and 45°C.
- Electrical Safety: The cell must be used with a battery management system that prevents overcharge beyond 3.65V, overdischarge, and short circuits.
- Physical Integrity: Do not disassemble, deform, short-circuit, or incinerate the cell to avoid thermal runaway or explosion.
Follow these steps to safely handle and charge the cell for the first time. Proper procedures ensure safe operation and maximize cycle life.
- Inspect Cell
Inspect the cell for any physical damage, deformation, or leakage before handling. - Verify Temperature
Verify that the ambient temperature is within the charging range of -10°C to 45°C. - Connect Protection Circuitry
Connect the cell to a battery management system or protection circuit module to ensure safe charging and discharging. - Charge Cell
Charge the cell using a compatible charger set to a constant current of 15A or less, and terminate charging when voltage reaches 3.65V. - Store Cell
Store the cell in a cool, dry environment when not in use, and avoid prolonged exposure to extreme temperatures.
How does the cycle life of the 3.2V 30Ah wide-temperature prismatic cell at -10°C compare to that at 25°C?
The cell delivers ≥1,800 cycles at 25°C under 1C/1C cycling, but at -10°C with 0.2C charge and 0.5C discharge, it achieves ≥200 cycles. This reduction reflects the increased stress on LFP chemistry at subzero temperatures, though the cell still provides reliable cold temperature operation.
What are the charging current limitations for this cell when operating at subzero temperatures below 0°C?
At -10°C to 0°C, the maximum continuous charge current is limited to 0.2C (6A), while at 0°C to 45°C, it supports up to 2C (60A). Charging is not recommended below -10°C. This ensures safe lithium intercalation and prevents lithium plating.
What safety and integration precautions are required when assembling a battery pack with this prismatic LFP cell?
The cell must not be disassembled, deformed, short-circuited, or incinerated. For battery pack assembly, appropriate cell balancing and protection circuitry must be utilized. Storage should be in a cool, dry environment, avoiding prolonged exposure above 55°C or below -40°C during operation.
This 3.2V 30Ah LFP prismatic cell is evaluated for its wide-temperature discharge from -40°C to 55°C and charging from -10°C, with 2C continuous charge and 4C continuous discharge at ambient, 2C discharge at -40°C, and a cycle life of ≥1800 cycles at 25°C.
Positive
- Wide temperature operation: Reliable discharge from -40°C to 55°C and stable charging from -10°C to 45°C, ensuring performance in extreme environments.
- High rate capability at cold temperatures: Supports 2C continuous charge at 0°C–45°C and 2C discharge at -40°C–0°C, with up to 4C discharge at 0°C–55°C, enabling robust power delivery under cold conditions.
Trade-offs
- Storage and environmental constraints: Cells must be stored in a cool, dry environment and not exposed to temperatures above 55°C or below -40°C during operation to avoid performance degradation.
- Reduced cycle life at low temperature: Cycle life drops to ≥200 cycles at -10°C with 0.2C/0.5C compared to ≥1800 cycles at 25°C, limiting long-term reliability in continuous cold operation.
