چکیده انگلیسی
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 gâ1) when cycled at low rates (44 mA gâ1), and a reversible capacity of 90 mAh gâ1 is obtained at high specific current (3 A gâ1). The PAA-based electrodes possess an excellent cycling ability with a capacity retention of 94% after 100 cycles. The present study demonstrate the possibility to overcome the dramatic capacity fading of V2O5 by a simple approach, permitting to obtain electrochemical performance similar to those of more complicated nano-architectures via the use of a greener electrode manufacturing process.
