Novel strategy for efficient conversion of biomass into N-doped graphitized carbon nanosheets as high-performance electrode material for supercapacitor

Probing the evolution in catalytic graphitization of biomass-based materials for enduring energetic applications

“…The resulting graphitized lignin was subsequently employed as an electrode material for the fabrication of supercapacitors. 70 The conducted tests revealed notable performance metrics for the supercapacitor, including a specific capacitance of 10.7 F g −1 at 0.5 A g −1 , a power density of 869.5 W kg −1 , an energy density of 15.7 W h kg −1 , and a remarkable capacitance retention of 100% even after 1500 cycles, even without requiring activation. These results underscore the favorable attributes of lignin-based graphitic carbonaceous materials in capacitor development.…”

“…Moreover, these biomaterials possess an abundance of heteroatoms (including N, O, S, and P), further enhancing their suitability by introducing additional active sites conducive to energy storage. 70,75,78 Converting biomass into nanostructured materials with high graphitic value provides a durable approach to the advancement of green energy and carbon neutralization.…”
