This cell requires storage in a dry, ventilated area between 15-30°C to prevent degradation and maintain performance. Exceeding rated charge/discharge currents or temperature thresholds can cause thermal runaway, fire, or personal injury.
- Storage Conditions: Store cells in a dry, ventilated area at 15-30°C to maintain electrochemical stability and safety.
- Charge Safety Limits: Charge only between 0°C and 60°C using a CCCV profile with thermal cut-off at 60°C to prevent overheating.
- Discharge Safety Limits: Discharge between -60°C and 60°C with thermal cut-off at 80°C to avoid thermal damage.
- Current Limits: Do not exceed the maximum continuous charge rate of 3C or discharge rate of 12C to preserve cell integrity.
- Prohibited Actions: Never disassemble, short circuit, or incinerate the cell as it may cause explosion or release of hazardous materials.
Follow these steps to safely initialize and handle the high-power lithium-ion cells. Proper charging, monitoring, and storage are critical to prevent thermal events and ensure long cycle life.
Required Equipment: CCCV-compliant battery charger, Temperature monitoring device
- Inspect cells
Inspect each cell for physical damage, such as dents or leaks, before initial use. - Charge with CCCV profile
Charge the cells using a CCCV profile with a current not exceeding 3C and a temperature cut-off at 60°C. - Monitor discharge temperature
Discharge at currents up to 12C continuous while monitoring the cell temperature to remain below 80°C. - Store properly
Store cells in a dry, ventilated area at 15-30°C when not in use to prevent capacity fade. - Avoid prohibited actions
Never disassemble, short circuit, or incinerate the cells to prevent explosion or fire.
How does increasing the discharge rate above 1C affect the cycle life of the NCA/Gr+SiOx 18650 cell?
Increasing discharge rate reduces cycle life significantly. The cell delivers ≥1000 cycles at 1C/1C (100% DOD), ≥500 cycles at 1C/4C (100% DOD), and ≥300 cycles at 2C/8C (80% DOD). For maximum longevity, operate at lower C-rates consistent with the specifications.
What charging protocol and temperature constraints are required to safely integrate this 18650 cell into a high-drain device?
Charge using a CCCV profile with a maximum continuous charge current of 3.0C and a thermal cut-off at 60°C. The charge temperature range is 0°C to +60°C, and the voltage window is 4.20V cut-off to 2.50V cut-off. Exceeding these parameters risks damage or thermal runaway.
What are the recommended storage conditions and safety precautions for the NCA/Gr+SiOx 18650 cells to preserve performance and prevent hazards?
Store in a dry, ventilated area between 15-30°C. Do not disassemble, short circuit, or expose to fire. The cells have ≤8.0 mΩ internal resistance and thermal cut-offs at 60°C for charging and 80°C for discharging. Always use the specified CCCV charge profile and protective hazardous-material packaging during transport.
The 18650 NCA/Gr+SiOx battery (4-pack) delivers 12C continuous discharge and operation down to -60°C, but requires charging above 0°C and thermal management to avoid cut-off at 80°C under heavy loads.
Positive
- High-rate 12C continuous discharge capability: Supports 12.0C maximum continuous discharge and 20.0C pulse discharge (10s), delivering exceptional power for demanding applications such as power tools and drones.
- Extreme low-temperature discharge performance: Discharge operation down to -60°C enables reliable battery function in severe cold environments, suitable for high-altitude research and cold-climate applications.
Trade-offs
- Charging prohibited below 0°C: Charge temperature range is 0°C to +60°C; charging at sub-zero temperatures is not supported, requiring temperature conditioning in cold environments.
- Thermal cut-off limits under heavy load: Maximum continuous discharge at 12C triggers thermal cut-off at 80°C, necessitating active thermal management or duty cycling to sustain high-rate operation.
