摘要: Abstract In this work the electrochemical characterization of V2O5 electrodes, prepared using polyacrylic acid (PAA) as binder, is presented. The obtained electrodes display stable high capacity values (250 mAh g−1) when cycled at low rates (44 mA g−1), and a reversible 90 mAh g−1 specific current (3 A g−1). PAA-based possess an excellent cycling ability with retention 94% after 100 cycles. present study demonstrate possibility to overcome dramatic fading by simple approach, permitting obtain performance similar those more complicated nano-architectures via use greener electrode manufacturing process.
