This document outlines the environmental storage and safety constraints for the high-energy lithium-ion pouch cell. Adherence to these constraints prevents degradation and ensures safe operation.
- Storage Temperature: Store the cell in a dry, ventilated area between 15°C and 30°C.
- Voltage Limits: Maintain cell voltage between 2.5 V and 4.3 V to prevent damage.
- Charge Temperature: Charge the cell only within the temperature range of 0°C to 45°C.
- Discharge Temperature: Discharge the cell only within the temperature range of -20°C to 45°C.
- Mechanical Integrity: Protect the cell from mechanical stress and keep in original packaging until use.
This procedure describes the initial handling and charging steps for the high-energy lithium-ion pouch cell. Following these steps ensures safe operation and prolongs cycle life.
Required Equipment: Constant-current/constant-voltage battery charger
- Inspect Cell
Inspect the cell for physical damage, swelling, or leakage before handling. - Verify Voltage
Verify the cell's open-circuit voltage is within 2.5 V to 4.3 V. - Connect Charger
Connect the cell to a constant-current/constant-voltage charger with a maximum current of 0.5 C. - Monitor Temperature
Monitor the cell temperature during charging, ensuring it does not exceed 45°C. - Store Safely
Store the cell at 15°C to 30°C in a dry, ventilated area when not in use.
How does the 370Wh/kg energy density of the NMC/Gr+SiC pouch cell trade off against cycle life under high-rate discharge conditions?
The cell delivers ≥370 Wh/kg at 0.2C with ≥500 cycles at 0.5C/0.5C cycling between 4.20V and 2.75V. While pulse discharge up to 10.0C (10s) and continuous discharge up to 5.0C are supported due to ≤1.5 mΩ internal resistance, the specified cycle life of ≥500 cycles is only guaranteed at 0.5C/0.5C. Operation at higher continuous discharge rates will reduce cycle life proportionally, but exact cycle life data under those conditions is not provided in the datasheet.
What are the critical charge voltage and temperature constraints for integrating this 3.5V nominal pouch cell into a battery pack?
The cell operates at 3.5V nominal with a voltage range of 4.30V to 2.50V. Standard charge current is 0.2C, maximum continuous charge is 0.5C, and charge temperature must be between 0°C and +45°C. Discharge temperature range is -20°C to +45°C. These voltage and temperature limits must be strictly enforced by the BMS to prevent overcharge, over-discharge, and thermal damage.
What storage and handling precautions are required for the 370Wh/kg high-energy density pouch cell to mitigate safety risks?
The cell is sensitive to mechanical stress and overcharge. Store in original packaging until use in a dry, ventilated area between 15-30°C. Do not disassemble or expose to fire. Always follow the specified charge/discharge profiles: charge 0-45°C, discharge -20 to 45°C, and never exceed 4.30V or drop below 2.50V to maintain structural integrity and avoid hazardous conditions.
This 370 Wh/kg NMC/Gr+SiC pouch cell delivers industry-leading gravimetric and volumetric energy density with exceptional rate capability up to 10C pulse, but requires strict adherence to charge temperature limits (0–45°C) and protection against mechanical stress and overcharge to maintain performance and safety.
Positive
- Ultra-high energy density: Delivers ≥370 Wh/kg gravimetric and ≥705 Wh/L volumetric energy density, enabling compact, high-performance designs for electric vehicles and portable electronics.
- Exceptional rate capability: Low AC resistance (≤1.5 mΩ) supports continuous discharge up to 5.0C and pulse discharge up to 10.0C (10s), meeting high-dynamic load demands.
Trade-offs
- Sensitive to mechanical stress and overcharge: The pouch cell requires careful handling to avoid mechanical damage and must strictly follow recommended charge profiles to prevent overcharge-induced failure.
- Narrow charge and storage temperature range: Charge operation is limited to 0–45°C, and storage requires dry, ventilated conditions at 15–30°C, restricting deployment in uncontrolled environments.
