This document outlines the environmental storage conditions, electrical safety limits, and mechanical handling constraints for the Atomfair 390Wh/kg NMC/SiC+Gr pouch cell. Adherence to these constraints is critical to prevent thermal runaway, capacity degradation, and physical damage.
- Storage Environment: Store the cell in a dry, ventilated area at 15°C to 30°C, away from flammable materials and direct sunlight.
- Charge Voltage and Current Limits: Charge at 0.2C standard, not exceeding 1.0C continuous within 15°C to 40°C, and never exceed 4.30 V.
- Discharge and Temperature Range: Discharge at 0.2C standard, up to 2.0C continuous, with pulse up to 5.0C for 5 seconds, within -20°C to +45°C.
- Mechanical and Overcharge Sensitivity: Avoid mechanical stress, deformation, and overcharge conditions; keep in original packaging until use.
- Cycle Life and Performance: Expect ≥500 cycles at 0.5C/0.5C between 4.20V and 2.75V at 25°C, with coulombic efficiency >99.5%.
Follow these steps to safely receive, inspect, and prepare the pouch cell for integration into a battery system. Proper handling prevents damage and ensures reliable performance.
- Inspect the Cell
Inspect the pouch cell for any physical damage, swelling, or deformation before removing from packaging. - Store Properly
Store the cell in a dry, ventilated area between 15°C and 30°C if not used immediately. - Set Charge Parameters
Set the charge current to 0.2C and the voltage limit to 4.30 V, ensuring ambient temperature is between 15°C and 40°C. - Connect to Charger
Connect the cell to a compatible charger with CC/CV mode and monitor voltage during charging. - Monitor Temperature
Monitor the cell temperature during charge and discharge to ensure it stays within the specified range.
What is the pulse discharge capability of the 390Wh/kg NMC/SiC+Gr pouch cell and how does it affect cycle life?
The cell supports pulse discharge up to 5.0C for 5 seconds at ≥50% SOC, enabling high dynamic loads. Despite its ultra-high energy density, it maintains a cycle life of ≥500 cycles at 0.5C/0.5C and 25°C, with coulombic efficiency >99.5%, indicating excellent stability under pulsed operation.
What are the voltage and temperature constraints for integrating this high-energy pouch cell into a battery pack?
The cell operates within a voltage window of 4.30 V to 2.50 V and delivers 41.0 Ah at 3.5 V. Charging is permitted from 0°C to +45°C, while discharge extends from -20°C to +45°C. Maximum continuous charge is 1.0 C and continuous discharge is 2.0 C, with a low AC resistance of ≤1.2 mΩ at 50% SOC.
What storage and handling precautions are required for the 390Wh/kg NMC/SiC+Gr pouch cell?
The cell is sensitive to mechanical stress and overcharge. Keep in original packaging until use, store in a dry ventilated area between 15–30°C, and follow the specified charge/discharge profiles. Do not disassemble or expose to fire. The soft pouch packaging requires careful handling to avoid physical damage.
This 390Wh/kg NMC/SiC+Gr pouch cell delivers ultra-high gravimetric and volumetric energy density with ≤1.2 mΩ internal resistance for high-rate pulse discharge, but requires careful handling to avoid mechanical stress and overcharge, plus controlled storage conditions.
Positive
- Ultra-high energy density: ≥390 Wh/kg and ≥810 Wh/L enable compact system designs for EVs, drones, and portable electronics.
- Low internal resistance: ≤1.2 mΩ supports continuous 2.0C discharge and 5.0C pulse discharge (5s) for demanding dynamic loads.
Trade-offs
- Mechanical and overcharge sensitivity: The cell is sensitive to mechanical stress and overcharge conditions; keep original packaging until use and follow recommended charge/discharge profiles.
- Controlled storage requirements: Store in a dry, ventilated area between 15-30°C to maintain performance and safety, typical for high-energy lithium-ion cells.
