Flexible self‐charging power cells (SCPCs) are fabricated from flexible graphene electrodes and Kapton shells. The cells can be charged from 500 to 832 mV within 500 s by periodic compressive stress (34 N, 1 Hz). The flexible SCPC can be efficiently charged from a small amount of mechanical energy, such as by finger pressing or a bicycle tire rolling.
