Sustainably‐derived hierarchical porous carbon from spent honeycomb for high‐performance lithium‐ion battery and ultracapacitors
Abstract
Spent honeycomb biomass as sustainable source is used to generate value added product, such as activated carbon. The generated activated carbon is characterized by X‐ray diffraction, Fourier transformed infra‐red spectroscopy, Raman spectroscopy, Scanning electron microscope, High‐resolution transmission electron microscope, and Brunauer‐Emmett‐Teller analyses. The activated carbon is explored as intercalation anode material for lithium‐ion battery in half‐cell and full cell as electrodes for ultracapacitor in aqueous and non‐aqueous electrolytes. The coin‐type CR‐2032 full cell lithium‐ion battery consists of the honeycomb‐derived carbon as anode and commercial LiCoO2 as cathode delivers discharge capacity of 140 mAh/g at C/5 rate with excellent cycling stability. On the other hand, the symmetric ultracapacitor consists of the carbon electrode exhibits energy density of 72 Wh/kg at a power density of 4800 W/kg with excellent coulombic efficiency as well as stability. The laboratory proto‐type battery and ultracapacitor devices are demonstrated to power a consumer electronics, namely green light emitting diode bulb for more than 3 hours and 20 minutes, respectively.
