摘　　要：生物质是优异电极材料的重要来源,植物基生物质在制备多孔炭材料方面具有独特的结构优势。本文以面条菜为原料,KOH为活化剂,探讨了不同比例的KOH溶液对炭材料微观形貌的影响,制备出一系列具有二维管束状的炭材料,通过扫描电镜、X射线衍射和拉曼光谱等物理手段对炭材料的结构进行了深入分析。结果表明当碱碳比为3:1时,炭材料SCLC-3含有微孔-介孔等丰富的孔隙结构,为电解液离子在炭材料中的传输和存储提供了有利条件,在电流密度为1A·g^(-1)时SCLC-3比电容高达290F·g^(-1),经过5000次充放电循环测试电容保留率高达98%,表明炭材料具有良好的循环寿命。将其制作成固态电极材料进行不同角度的弯折,结果显示其电化学性能几乎没有发生变化,呈现出较好的抗弯折性能。Biomass was considered as an important source of excellent electrode materials,especially plant-based biomass with u-nique structural advantage in preparing porous carbon materials.In this paper,a series of two-dimensional tube carbon materials with hierarchical pore structure was prepared from silene conoidea L acted as raw materials with different proportions of KOH acted as activator.Meanwhile,the structure of the materials was analyzed by scanning electron microscopy,S-ray diffraction and Raman.When the alkali to carbon ration was 3:1,carbon materials SCLC-3 exhibited abundant pore structure with micropore and meso-pore,providing favorable conditions for the transport and storage of electrolyte ions.The results showed that SCLC-3 displayed a high specific capacitance of 290 F·g^(-1)at a current density of1 A·g^(-1),with a capacitance retention as high as 98%after 5000 cycles of charge and dis-charge.At the same time,the electrochemical performance of the electrode materials almost remained unchanged at different bending angles.
