      Vanadium dioxide (VO2) monoclinic nanosheets were synthesized by a solvothermal method and carbonized iron-polyaniline (C-FP) nanograins were prepared by pyrolysis of iron-polyaniline (PANI) mixture under nitrogen ambient. An asymmetric device (VO2//C-FP) was evaluated with VO2 and C-FP as positive and negative material electrodes in aqueous 6 M KOH electrolyte respectively. The asymmetric supercapacitor (VO2//C-FP) exhibited a 47 mA h g-1 specific capacity and a specific energy of 30Wh kg−1 with an associated specific power of 713 W kg−1 at a gravimetric current of 1 A g−1 in a potential window of 1.6 V. It also displayed an 89% energy efficiency after 10000 galvanostatic charge-discharge cycles with a large improvement after ageing test at a gravimetric current of 10 A g-1. ; http://scitation.aip.orgcontent/aip/journal/adva ; am2019 ; Physics
