Cell must be stored at 15°C–35°C in a dry environment with humidity controlled to 65%±20% RH. Over-discharge below 1.5V and over-charge above 3.45V must be strictly avoided using a dedicated BMS.
- Storage Environment: Store cells in a vacuum-sealed package with desiccant to prevent moisture ingress.
- Voltage Limits: Maintain cell voltage between 1.5V and 3.45V at all times to prevent damage or safety hazards.
- BMS Requirement: Pair the cell with a BMS configured for sodium-ion voltage windows to ensure safe operation.
- Mechanical Handling: Use only manufacturer-approved cell holders and busbars to avoid mechanical stress and short circuits.
- Disposal: Dispose of cells in accordance with local regulations for sodium-based batteries.
Inspect the cell upon receipt for any physical damage or swelling. Always use a dedicated BMS to monitor voltage and temperature during operation.
Required Equipment: Battery Management System (BMS), Manufacturer-approved cell holder, Busbar, Calibrated voltmeter
- Inspect Packaging
Inspect the vacuum-sealed packaging for any punctures or moisture ingress before opening. - Measure Voltage
Verify the cell open-circuit voltage is between 1.5V and 3.45V using a calibrated voltmeter. - Install BMS
Connect the cell to a dedicated BMS configured for the sodium-ion voltage window of 1.5V to 3.45V. - Secure Cell
Mount the cell in a manufacturer-approved holder and attach busbars using recommended torque specifications. - Set Storage Conditions
Store the cell in a temperature-controlled environment between 15°C and 35°C with humidity below 65% RH. - Monitor Charging
Charge the cell at a maximum rate of 1.0C and never exceed 3.45V to prevent over-charge. - Control Discharge Limits
Avoid discharging below 1.5V and limit continuous discharge to 8C with pulse discharge up to 10C for 30 seconds.
How does the lower average voltage of 2.86V for this sodium-ion cell affect system design compared to lithium-ion?
The 2.86V average voltage is significantly lower than typical lithium-ion cells (3.6–3.7V), meaning more cells must be connected in series to achieve the same pack voltage, increasing module complexity and balancing requirements. However, the sodium-ion chemistry offers intrinsic safety, cost advantages from abundant sodium resources, and a wide discharge temperature range from -40°C to 60°C, which may offset the series-count penalty in applications like low-speed EVs, telecom backup, or grid storage.
Is this sodium-ion cell compatible with existing lithium-ion battery management systems and assembly equipment?
Compatibility requires a dedicated BMS configured for the sodium-ion voltage window of 1.5V–3.45V per cell, as standard lithium-ion BMS voltage thresholds (e.g., 2.5V–4.2V) are mismatched. The cell is compatible with standard lithium-ion assembly equipment, but only manufacturer-approved cell holders and busbars should be used to ensure proper mechanical and electrical interface.
What are the storage and handling requirements for the 50Ah sodium-ion prismatic cell to ensure safety and performance?
Cells must be stored at 15°C–35°C in humidity-controlled, vacuum-sealed packaging with individual anti-static foam isolation and desiccant bags. Over-discharge below 1.5V and over-charge above 3.45V must be avoided via a dedicated BMS. Dispose of cells in accordance with local regulations for sodium-based batteries, and use only manufacturer-approved cell holders and busbars during system integration.
This 50Ah sodium-ion prismatic cell delivers high-rate discharge capability up to 8C continuous and 10C pulse, along with a wide operating temperature range for discharge from -40°C to 60°C, making it suitable for demanding energy storage applications; however, it requires a dedicated BMS for precise voltage control and careful storage within 15°C–35°C and controlled humidity to prevent performance degradation.
Positive
- High continuous and pulse discharge: Supports up to 8C continuous discharge and 10C pulse for 30 seconds at 100% SOC (25°C), enabling high-rate applications such as low-speed EVs and UPS systems.
- Extreme temperature tolerance: Discharge from -40°C to 60°C and charge from 0°C to 55°C without auxiliary heating, ensuring reliable performance in harsh climates.
Trade-offs
- Dedicated BMS voltage control required: Must be paired with a BMS calibrated for sodium-ion voltage windows (1.5V–3.45V) to prevent over-discharge or over-charge, adding system integration complexity.
- Sensitive storage and humidity conditions: Recommended storage at 15°C–35°C and operation within 65%±20% RH; cells ship in humidity-controlled packaging, indicating sensitivity to moisture that requires controlled environment handling.
