Materials 17(15): 3782. doi:10.3390/ma17153782. 1996-1944 http://hdl.handle.net/20.500.12327/3407 https://doi.org/10.3390/ma17153782 In this work, iron hexacyanoferrate (FeHCF—Prussian blue) particles have been grown onto a reduced graphene oxide substrate through a pulsed electrodeposition process. Thus, the prepared FeHCF electrode exhibits a specific volumetric capacitance of 88 F cm−3 (specific areal capacitance of 26.6 mF cm−2) and high cycling stability with a capacitance retention of 93.7% over 10,000 galvanostatic charge–discharge cycles in a 1 M KCl electrolyte. Furthermore, two identical FeHCF electrodes were paired up in order to construct a symmetrical supercapacitor, which delivers a wide potential window of 2 V in a 1 M KCl electrolyte and demonstrates a large energy density of 27.5 mWh cm−3 at a high power density of 330 W cm−3. eng Attribution 4.0 International Prussian blue anchored on reduced graphene oxide substrate achieving high voltage in symmetric supercapacitor info:eu-repo/semantics/article
