ABSTRACT

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.
