Low-cost and high energy density asymmetric supercapacitors based on polyaniline nanotubes and MoO3 nanobelts

Asymmetric supercapacitors (ASCs) with high energy density are assembled based on the pseudocapacitance of both electrodes, which use polyaniline (PANI) nanotubes as positive electrodes and MoO₃ nanobelts as negative electrodes in a 1 M H₂SO₄ aqueous electrolyte.
