Celery-derived porous carbon materials for superior performance supercapacitors

Abstract

Supercapacitors are of paramount importance for next-generation applications, demonstrating high energy output, an ultra-long cycle life and utilizing green and sustainable materials. Herein, we utilize celery, a common biomass from...

Biomass Porous Carbon Derived from Celery Leaves with High Capacitance for Supercapacitor

“…The TEM images (Figure S1d) also explain the deficiency of any graphitic domains, revealing the non-crystalline property of aGCL-800. [15] Therefore, suitable temperature and activator action promote aGCL-800 to have a large number of pore size structure at the same time, which successfully improves the SSA of the electrode material and is conducive to the electrolyte and electrode material adequately contact.…”

“…Thus, the microporous nature would limit the diffusivity of the electrolyte ion in the electrode interface, leading to the decrement in Cs. [15] . The aGCL-800 still has the highest Cs even at a high current density.…”

Rapid and easy preparation of self-supporting La-mixed NiMoO4 nanofloral materials and their capacitance properties

“…[6][7][8][9] The low energy density limits the development and application of capacitors and is also the main factor affecting their performance. [10][11][12] According to the energy density E = 1/2CV 2 , it can be seen that the specific capacitance (C) and voltage (V) affect the energy density of supercapacitors. 13,14 Therefore, developing and designing electrode materials with excellent performance through experiments to improve the specific capacitance, thereby increasing the energy density of supercapacitors while maintaining their high power density level, has become a key problem in addressing supercapacitors.…”

CoMoO4 Nanoflowers Doped with La Element for Advanced Electrode Materials

“…Supercapacitors are considered one of the most promising energy storage devices in the energy field due to their high power density, fast charging and discharging, green environmental protection, and long service life [9][10][11][12][13][14][15]. The low energy density has limited the development and application of capacitors and is also the main factor affecting their performance [16][17][18][19]. According to the energy density E = 1/2CV 2 , it can be found that the specific capacitance (C) and voltage window (V) directly affect the energy density.…”
