Unlocking the full potential of citric acid-synthesized carbon dots as a supercapacitor electrode material via surface functionalization

Abstract

Functionalization of green-emitting carbon dots with hyperbranched bis(methylol)propionic acid (bis-MPA) polyester hydroxyl polymers resulted in the successful passivation of surface defects and hence better performance in supercapacitors.

Polyanilines from spent battery powder and activated carbon: Electrodes for asymmetric supercapacitor cell

“…Using carbon materials is high cycle life stability, high power density, good electrical conductivity, chemical stability, and a large surface area. These can be used as both anode and cathode electrode material 31–34 . However, the commercial production of carbon materials for electrode materials is becoming challenging.…”
