Aniline tetramer conjugated N-doped graphene aerogel enabling efficient pH-universal aqueous supercapacitors

The development of novel negative electrode (anode) materials for efficient aqueous supercapacitors (SCs) remains appealing yet significantly challenging. Here we propose an aniline tetramer conjugated nitrogen-doped graphene aerogel (AT-NGA) as the anode material, exhibiting a maximum capacitance of 699.1F g
