Store this lithium-ion cell in a dry, ventilated area between 15°C and 30°C to prevent thermal degradation and internal short circuits. Do not disassemble, short circuit, or expose to fire to avoid hazardous chemical release, explosion, or electrical shock.
- Charge Profile Constraint: Charge only with a constant current constant voltage (CCCV) profile with a thermal cut-off at 60°C.
- Discharge Cut-off Constraint: Discharge cut-off temperature is set at 80°C; do not exceed the rated continuous or pulse discharge currents.
- Extreme Temperature Pre-conditioning: For operation below -60°C, apply a pre-conditioning cycle as recommended to maintain electrochemical stability.
- Prohibited Handling Actions: Never disassemble, puncture, short circuit, or incinerate the cell to prevent thermal runaway and toxic gas release.
- Storage Environment Requirement: Maintain storage in a dry, ventilated area at 15°C to 30°C to minimize self-discharge and electrolyte degradation.
This procedure describes the safe handling, pre-conditioning, and charging steps required to operate the cell within its thermal and electrical limits. Adherence to these steps prevents thermal runaway and ensures reliable power delivery.
Required Equipment: CCCV charger with adjustable thermal cut-off
- Inspect the Cell
Inspect the cell for physical damage, terminal corrosion, or any signs of leakage before use. - Prepare Storage Environment
Transfer the cell to a dry, ventilated area with ambient temperature maintained between 15°C and 30°C. - Connect to Charger
Connect the cell to a CCCV charger set to a maximum voltage of 4.20 V and a thermal cut-off at 60°C. - Monitor Charging Parameters
Verify that the charging current does not exceed 5.0 C and that the cell temperature remains below 60°C throughout the cycle. - Confirm Discharge Limits
Confirm that the discharge cut-off temperature is set to 80°C and do not exceed 15.0 C continuous or 30.0 C pulse discharge. - Apply Pre-conditioning for Extreme Cold
Apply a manufacturer-recommended pre-conditioning cycle if the cell will be discharged below -60°C. - Store After Use
Store the cell at 50% state of charge in a dry, ventilated area between 15°C and 30°C for long-term storage.
How does the cycle life of the tabless 21700 cell degrade under high-rate discharge conditions?
Cycle life degrades proportionally with higher discharge rates. At 1C/1C 100% DOD it delivers ≥1000 cycles, but at 2C/10C 80% DOD it drops to ≥300 cycles. This trade-off between power output and longevity must be factored into high-rate pulsed or continuous load designs.
Can this battery be charged at sub-zero temperatures for remote or cold-climate applications?
No, the specified charge temperature range is 0°C to +60°C; charging below 0°C is not supported. Discharge is possible down to -60°C with pre-conditioning, but charging must remain within the 0–60°C window to avoid damage or safety risks.
What specific storage and operational constraints apply to the tabless 21700 cell to prevent thermal runaway?
Store in a dry, ventilated area between 15–30°C. Charge using a CCCV profile with a thermal cut-off at 60°C, and discharge with a cut-off at 80°C. Do not exceed rated currents, disassemble, short circuit, or expose to fire to maintain safe operation.
This tabless 21700 Li-ion battery (5.0Ah, 3.6V) combines an NCM/SiOx chemistry with an ultra-low-resistance tabless architecture (≤3.5 mΩ) to deliver 15C continuous and 30C pulse discharge, while supporting a -60°C to +60°C discharge range—though charging below 0°C is restricted and extreme cold use may require pre-conditioning.
Positive
- Tabless design minimizes internal resistance: The tabless architecture reduces AC internal resistance to ≤3.5 mΩ, lowering heat generation and enabling sustained 15.0C continuous discharge and 30.0C pulse discharge (10s) for high-power applications.
- Ultra-wide discharge temperature range: Capable of discharging from -60°C to +60°C, the cell operates reliably in extreme cold and hot environments, making it suitable for aerospace, automotive, and outdoor power systems.
Trade-offs
- Charge limited to above-freezing temperatures: The charge temperature range is restricted to 0°C to +60°C, so charging in sub-zero environments is not permitted without active thermal management of the cell.
- Pre-conditioning needed at -60°C discharge: For extreme low-temperature operation at -60°C, the manufacturer notes that pre-conditioning may be required, adding a preparatory step before full discharge capability is achieved.
