Fast Charging Battery (FCB™)

Pre-heated Fast Charging Method for Li-ion Batteries


A 10-Minute, 200 Mile Fast Charging Method that Rapidly Preheats and Charges a Li-ion Cell

 An elevated temperature of 60°C eliminates Li plating and limits exposure time to prevent severe solid-electrolyte-interphase growth.


Excellent Cyclability

FCB cells retain 91.7% capacity after 2,500 cycles of 6C charge to 80% SOC. The total charge time only increases marginally upon cycling.

Independently Tested and Verified

 The Argonne National Laboratory has tested and verified this heated charge method achieves 10 minute charging to 80% charge with 4.5% degradation over 500 XFC cycles.
