This document specifies the environmental, electrical, and handling constraints for the JLY-YF-B02 electrolyte pouch cell. Adherence to these limits is essential to prevent capacity degradation, electrical hazards, or thermal runaway.
- Voltage Limits: Operate the cell within a voltage range of 3.0 V to 4.3 V to avoid overdischarge or overcharge damage.
- Operating Temperature Range: Charge the cell only between 0°C and 45°C and discharge only between -20°C and 55°C.
- Storage Condition: Store the cell at 25°C and 100% state of charge, ensuring a storage performance coefficient K ≤ 0.06.
- Charging Rate for Cycle Life: To achieve the specified cycle life, charge the cell at a constant current of 0.2C (0.6 A for 3 Ah nominal capacity).
This procedure covers the initial inspection, charging, and discharge operation of the JLY-YF-B02 pouch cell. Follow these steps to ensure safe handling and optimal performance.
Required Equipment: Constant current power supply
- Inspect the cell
Inspect the pouch cell for any visible damage, swelling, or leakage before use. - Connect charging circuit
Connect the cell to a constant current power supply with correct polarity, setting the charge current to 0.2C (0.6 A for a 3 Ah cell). - Charge the cell
Charge the cell at 0.2C until the voltage reaches 4.3 V, then terminate the charge. - Verify temperature during charge
Ensure the ambient temperature during charging remains between 0°C and 45°C. - Discharge the cell
Apply a load at 1C (3 A) for normal operation or up to 3C for continuous discharge, monitoring voltage to stay above 3.0 V and temperature within -20°C to 55°C.
What is the cycle life trade-off between the Standard and Upgraded versions of the JLY-YF-B02 electrolyte for lithium metal pouch cells?
The Standard version (V.400) delivers ≥400 Wh/kg with ≥250 cycles, while the Upgraded version (V.420) achieves ≥420 Wh/kg with ≥350 cycles, offering a 20 Wh/kg energy density increase and 100 additional cycles at the cost of a more advanced formulation. Both versions use the same JLY-YF-B02 electrolyte in a 4*50*78mm pouch cell format with 3 Ah nominal capacity.
What are the operating temperature constraints for integrating the JLY-YF-B02 pouch cell into high-altitude UAV platforms?
The cell operates with a charge temperature range of 0–45°C and a discharge range of –20–55°C, which must be considered for stratospheric applications where ambient temperatures can drop below –20°C during discharge but require controlled charging conditions above 0°C. This constraint is critical for HALE UAVs and stratospheric exploration platforms listed as primary applications.
What storage conditions are required to maintain the JLY-YF-B02 cell's capacity retention and prevent dendrite growth?
The cell exhibits a storage performance factor K ≤0.06 at 25°C and 100% state of charge, indicating minimal capacity fade under standard storage conditions. The proprietary B02 electrolyte suppresses lithium dendrite formation and maintains a robust SEI layer for extended cycle life, but storage at elevated temperatures or extreme SoC may accelerate degradation beyond the specified K value.
The JLY-YF-B02 electrolyte system delivers industry-leading specific energy density for lithium metal pouch cells, with a trade-off of moderate cycle life and a restricted charge temperature range, making it suitable for weight-critical applications like HALE UAVs rather than long-life stationary storage.
Positive
- Ultra-high specific energy density up to 420 Wh/kg: The JLY-YF-B02 electrolyte enables lithium metal pouch cells to reach a peak specific energy of 420 Wh/kg, offering a significant weight advantage for aerospace and UAV applications.
- Extended cycle life with dendrite suppression: Proprietary B02 formulation suppresses lithium dendrite growth and maintains SEI stability, achieving up to 350 cycles at 0.2C/1C test conditions in the upgraded version.
Trade-offs
- Limited cycle life for high-cycle applications: Even the upgraded version achieves only 350 cycles, which may be insufficient for applications requiring thousands of cycles without replacement.
- Restricted charge temperature window: Charging is limited to 0-45°C, preventing low-temperature charging below freezing, which could be a constraint in cold environments.
