    Sodium Battery Cycle Life Test

    1. Test conditions: temperature: 25±3℃, relative humidity: 45~85%, atmospheric pressure: 86~106Kpa

    2. Test equipment: Charge and discharge test cabinet

    Test method: The battery cell is charged at 0.5P constant power to 3.9V and then placed on hold for 30 minutes. Then it is discharged at 0.5P constant power to 1.5V and placed on hold for 30 minutes before the next cycle.

    4. Judgment criteria: Cycle ≥ 2000 times, Capacity retention rate≥ 80%

    Test results:  

    After 450 cycles, the capacity retention rate is 97.1%, which is much higher than the judgment standard (2000 cycles ≥80%).

    The data shows that the battery cell has extremely low attenuation in the initial cycle, excellent performance stability, and meets the long-term cycle life expectations.

    Conclusion: The current test results are ideal, the battery cell cycle life performance is excellent, and meets the design goals.
