Hollow　V2O5　spheres　constructed　from　plate-like　particles　were　synthesized.　These　materials　exhibited　a　tremendous　pseudocapacitance　effect　with　a　high　capacitance　of　479　Fg-1　at　5　mV　s-1　when　used　as　supercapacitor　electrodes　in　a　solution　of　5　M　LiNO3.　After　the　surface　of　hollow　V2O5　spheres　was　coated　with　PPy,　the　composite　electrode　was　formed　and　its　electrochemical　properties　were　also　improved.　This　composite　material　exhibited　the　capacitances　of　559　Fg-1　at　3　A　g-1　by　GCD　and　566　F　g-1　at　5　mV　s-1　by　CV,　respectively.　At　the　same　time,　the　capacity　retentions　of　70%　and　66%　were　respectively　achieved　even　after　100　cycles.　©　2013　Elsevier　Ltd.　All　rights　reserved.
