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.
