摘　　要：研究了1100、1600和2000℃下制备的聚丙烯腈基碳毡电极,结果表明2000℃下制备的碳毡电极在未改性处理前,电化学性能要优于1100、1600℃下制备的碳毡电极;对碳毡通过硫酸、硝酸、盐酸、热处理进行改性处理进行比较,结果显示:经过硝酸处理5h和450℃下热处理2h后,3种温度下制备的碳毡电极性能均得到明显提升,2000℃下制备碳毡电极改性效果最好,可用于钒液流电池作为电极。The PAN-carbon felt electrodes that prepared at three different temperatures of 1100℃,1600℃ and2000℃ were studied.The results showed that the electrochemical performance of electrodes which prepared at 2000℃without modification was superior to them that prepared at 1100℃ and 1600℃.Through the modification by H_2SO_4,HNO_3,HCl and heat-treatment at 450℃for 2h,The results showed that the electrode prepared at 2000℃ which was suitable for materials of vanadium flow batteries had better electrochemical performance.
