%X 本研究以废弃林作物橘皮为原材料，采用热分解法结合化学活化改性技术，成功制备橘皮基多孔生物炭材料(KC)。本文分析了生物炭材料的微观形貌和孔结构，利用电化学工作站对材料进行了循环伏安、恒流充放电和交流阻抗等测试。结果表明：KC具有多维度、多层次、多孔隙的微结构，比表面积高达1630 m<sup>2</sup>？g<sup><span>？</span>1</sup>。KC表现出优异的双层电容特性，在1 A/g的电流密度下，比电容为230 F/g。并且，当电流密度为20 A/g时，其比电容仍维持在184 F/g，表现出优异的倍率性能。<br />
In this study, orange peel-based porous carbon material (KC) was successfully prepared by thermal de-composition combined with chemical activation modification technology using discarded forest crop orange peel as raw material. This study analyzed the surface structure and microstructure of po-rous carbon material. Cyclic voltammetry, constant current charge-discharge and AC impedance were measured by the electrochemical workstation. The results reveal that KC has a mul-ti-dimensional, multi-level and porous morphological structure with a specific surface area of up to 1630 <span>m</span><sup>2</sup><span>？g</span><sup>？1</sup>. KC exhibits excellent double-layer capacitance characteristics, with a specific capaci-tance of 230 F/g at a current density of 1 A/g. Moreover, when the current density is 20 A/g, the specific capacitance remains at 184 F/g, showing excellent multiplier performance.
