构建类莫尔结构木质素基炭电极以高效提升光辅助超级电容器性能
Construction of Moiré-like lignin based carbon electrodes to efficiently improve the performance of photo-assisted supercapacitors
摘要
Abstract
Conventional lignin-based carbons typically have sluggish ion transport and a limited number of active sites,which restrict their performance as electrodes in supercapa-citors.A Moiré-like morphology was engineered by the in-situ deposition of lignin carbon onto DVD matrix onto lignin carbon for the fabrication of a photo-assisted supercapacitor(PASC).The Moiré-like structure modulates light propaga-tion across different frequencies by dispersion effects,thereby increasing surface light absorption and improving the electrochemical performance of the PASC.Under illumination,the carbon has a specific capacitance of 253.5 F g-1 at 0.5 A g-1,corresponding to a 35.6%improvement over one without this grating surface(186.9 F g-1).A symmet-rical capacitor using this material has an areal capacitance of 58.84 mF cm-2 and an energy density of 4.46 Wh kg-1 at a power density of 365.2 W kg-1,maintaining 85.2%of its initial capacitance after 5000 cycles,thus demonstrating excellent cycling stability.This work suggests a cost-effective strategy to simultaneously improve the light-harvesting ability and capacitive per-formance of PASCs.关键词
