The porous carbons with high specific surface area and excellent electrochemical properties were prepared using three types of green needle coke as raw materials. Electrochemical performances of the porous carbons derived from different microstructure green needle coke were investigated. The XRD and Raman spectra demonstrated that the content of the ordered carbon microcrystals were decreased and the content of amorphous and cross-linked structure were increased in the porous carbons with comparison to the raw materials. The results of N₂ adsorption–desorption analysis verified that the content of ordered microcrystalline structure in the raw materials evidently influence the specific surface area and pore size distribution of the porous carbons. The porous carbon with 1665 m² g⁻¹ specific surface area and 2.89 nm average pore size has shown that the specific capacitance was 288 F g⁻¹ at the current density 1 A g⁻¹. Furthermore, the capacity retention was 94.93% and the Coulombic efficiency was 92.87% after 5000 charge/discharge cycles.

以三种生针状焦为原料，制备了比表面积大，电化学性能优良的多孔碳。研究了不同显微结构的生绿色针状焦炭衍生的多孔碳的电化学性能。XRD和拉曼光谱表明，与原料相比，多孔碳中有序碳微晶的含量减少，无定形和交联结构的含量增加。N ₂吸附-解吸分析的结果证实，原料中有序微晶结构的含量明显影响多孔碳的比表面积和孔径分布。1665 m ²  g的多孔碳^-1的比表面积和2.89纳米的平均孔径表明，比电容为288 F G ^-1处的电流密度1 A G ^-1。此外，在5000次充电/放电循环后，容量保持率为94.93％，库仑效率为92.87％。
