Ultrafast Fabrication of H₂SO₄, LiCl, and Li₂SO₄ Gel Electrolyte Supercapacitors with Reduced Graphene Oxide (rGO)-LiMnO_x Electrodes Processed Using Atmospheric-Pressure Plasma Jet.

ABSTRACT: Pastes containing reduced graphene oxide (rGO) and LiCl-Mn(NO₃)₂·4H₂O are screen-printed on a carbon cloth substrate and then calcined using a nitrogen atmospheric-pressure plasma jet (APPJ) for conversion into rGO-LiMnO_x nanocomposites. The APPJ processing time is within 300 s. RGO-LiMnO_x on carbon cloth is used to sandwich H₂SO₄, LiCl, or Li₂SO₄ gel electrolytes to form hybrid supercapacitors (HSCs). The areal capacitance, energy density, and cycling stability of the HSCs are evaluated using electrochemical measurement. The HSC utilizing the Li₂SO₄ gel electrolyte exhibits enhanced electrode-electrolyte interface reactions and increased effective surface area due to it
