Winding Type Supercapacitor
Winding Type Supercapacitor is a double-layer capacitor that synchronously winds the positive electrode, separator, and negative electrode into a cylindrical battery cell, and then encapsulates it in a metal (steel/aluminum) shell(EDLC)


Features:
1. Extremely high power density
    Capable of millisecond to second fast charging/discharging, instantly outputting high current (10~1000A).
    The internal resistance is extremely low (m Ω level), and the multi pole ear design can further reduce the internal resistance.
2. Ultra long cycle life
    500000 to 1 million charge and discharge cycles (1000 times that of lithium batteries).
    Capacity decay is extremely slow and maintenance free.

3. Wide temperature operation

    Standard: -40 ℃~+70 ℃; High temperature type can reach -40 ℃~+85 ℃.
    The low-temperature performance is far superior to lithium batteries.
4. Safety and Environmental Protection
    No risk of explosion or fire; Free of heavy metals, environmentally friendly.
5. cost-effective
    Automated mass production, good consistency, and controllable cost.

Applications:
1. Automotive Electronics
    Car start stop system, low-temperature start assist, hybrid/electric vehicle braking energy recovery.
2. Industrial energy storage

    Smart meter/water meter/gas meter backup power supply in case of power failure UPS、 Wind power variable pitch backup.

3. rail transit

    Subway/tram energy recovery, short-term traction, emergency door opening.

4. Consumer/Medical/Military Industry

    Smart door locks, LED flashing, power tools, medical equipment, military high reliability pulse power supply.
