    Fast Charge Ability

    Grepow shaped batteries have adopted the stacking technology while applying Grepow's unique high power electrode formulation and manufacturing process, the batteries of fast charging and discharging at different rates can be designed. Grepow is the largest manufacturer for the Chinese high magnifying power lithium polymer battery, the fast charging is based on the high power cell, and it is also one of the Grepow's core technology. It has the following advantages:
  • 01
    Fast charging
    Grepow shaped batteries can be charged up to 3C or 5C, which is three times faster than the regular battery charging time.
  • 02
    Stable temperature
    During the fast charging process, the temperature will rise stably. The surface temperature of the battery will not exceed 65 degrees Celsius.
  • 03
    Long and durable
    After fast charging over 500 times, still remained up to 80% capacity.
  • 04
    Safe and reliable
    Corresponding to IEC, UL, PSE, UN38.3 and other lithium battery safety standards.
  • Bendable

    Here is a test case of the bending performance of a shaped battery:Charge the battery to 3.83v and fix the battery to the surface of the white PVC card. Fix the cell pole card to the bending and torsion tester, 15 degrees forward and backward, and 30 degrees total distortion, for bending and torsion test.

    After the bending and torsion test of the 0.45mm ultrathin cell for 9000 times, the surface of the cell was folded and the internal pole sheet had creases. The internal resistance increased by about 45%. The voltage before and after the bending and torsion basically remained unchanged.

    Shaped Batteries in Low Temperature

    Grepow's shaped batteries can be made to operate in environments with low temperature of -50℃ to 50℃. Under low temperature, the batteries can achieve a lower internal resistance and, thus, a high discharge rate. Compared with traditional Lithium Polymer batteries, Grepow's batteries have broken through the discharge temperature limits of -20℃ to 60℃.

    They are able to discharge over 60% efficiency at 0.2C at -40℃ and discharge over 80% efficiency at 0.2C at -30℃. When charged at 20℃ to 30℃ by 0.2C, the capacity can maintain above 85% after 300 cycles. The batteries can be ready for mass production, and they have been widely used in cold climates and military products.
