Patent ID: 11996238

Abstract:
There is disclosed a process of producing a hybrid super-capacitor (HSC) electrode, the process comprising performing nitridation-induced in situ coupling of Ni—Co4N nanoparticles in an N-doped carbon matrix, wherein the resultant hybrid super-capacitor (HSC) electrode is a Ni—Co4N@NC electrode. The resultant hybrid super-capacitor (HSC) electrode is a self-supported metal nitride coordinated with N-doped carbon, wherein the nitridation-induced in situ coupling is performed via a facile pyrolysis of layered Ni—Co hydroxide decorated on polyaniline (PANI) nanotubes on the basis of a carbon cloth (CC). Also disclosed is a hybrid supercapacitor cell assembled by employing Ni—Co4N-2@NC as a positive electrode and AC as a negative electrode with a PVA (poly vinyl alcohol)/KOH as a gel electrolyte.
