  • How is the lithium ion safety feature achieved?

    Diaphragm 135 ℃ automatic shutdown protection, using internationally advanced Celgas2300PE-PP-PE three-layer composite membrane. When the temperature of the battery reaches 120 ℃, the membrane holes on both sides of the PE composite membrane are closed, the internal resistance of the battery increases, and the internal temperature of the battery slows down. When the temperature of the battery reaches 135 ℃, the PP membrane hole is closed, the battery is internally open, and the temperature of the battery is no longer increased, ensuring the safety and reliability of the battery.
