Electrochemical polymerization of aniline on carbon-aluminum electrodes for energy storage

► A new energy storage electrode, based on a composite of Al/C/PANi is reported. ► Synthesis occurs in aqueous media and is transferable to non-aqueous environments. ► Charge/discharge performance studies show similar performance as Pt/PANi electrodes. ► The specific capacity for the Al/C/PANi films are >125 mAh g−1.
