| 1 | Self-assembled dandelion-like NiS nanowires on biomass-based carbon aerogels as electrode material for hybrid supercapacitors显示文摘Carbon aerogels derived from biomass have low specific capacity due to the underutilized structure,limiting their application in high-performance supercapacitors.In this work,the hierarchical nickel sulfide/carbon aerogels from liquefied wood(LWCA-NiS)were synthesized via a simple two-step hydrothermal method.Benefitting from the unique 3D coral-like network structure of LWCA,selfassembled NiS nanowires with the dandelion-like structure showed high specific surface(389.1 m^(2)·g^(−1))and hierarchical pore structure,which increased affluent exposure of numerous active sites and structural stability,causing superior energy storage performance.As expected,LWCA-NiS displayed high specific capacity(131.5 mAh·g^(−1) at 1 A·g^(−1)),good rate performance,and highly reversible and excellent cycle stability(13.1%capacity fading after 5000 cycles)in the electrochemical test.Furthermore,a symmetrical supercapacitor using LWCA-NiS-10 as the electrode material delivered an energy density of 12.7 Wh·kg^(−1) at 299.85 W·kg^(−1).Therefore,the synthesized LWCA-NiS composite was an economical and sustainable candidate for the electrodes of highperformance supercapacitors. | Chunfei Lv Ranran Guo Xiaojun Ma Yujuan Qiu | 2023 | Frontiers of Materials Science2023，17，3： | 0 |
