Ultrathin printable graphene supercapacitors are demonstrated, based on solution‐processed electrochemically exfoliated graphene hybrid films on an ultrathin poly(ethylene terephthalate) substrate, exhibiting an unprecedented volumetric capacitance of 348 F cm −3 , an ultrahigh scan rate of 2000 V s −1 , and AC line‐filtering performance.
