| 摘 要： | 为了研究苯丙氨酸的电化学储锂活性,首先借助傅立叶红外光谱(FTIR)和扫描电镜(SEM)对苯丙氨酸的微观结构及形貌进行了表征,然后将其用作锂离子电池负极活性材料,并通过恒流充/放电、循环伏安(CV)和交流阻抗(AC)技术研究了其电化学脱/嵌锂性能.结果表明:苯丙氨酸负极材料在0.1C循环充/放电50次后,可逆放电比容量为55.2 mAh·g-1;同时表现了良好的倍率性能,表明有机苯丙氨酸作为锂离子电池负极活性材料的良好可行性.

| Abstract: | In order to investigate electrochemical Li-storage activity of phenylalanine,the microstructure and morphology of phenylalanine were studied in terms of Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM).When it was used as the anode active materials of lithium ion battery,the corresponding electrochemical performances were investigated by galvanostatic charge/ discharge,cycle voltammograms (CV) and alternating current (AC) impedance spectroscope.The results show that phenylalanine-based anode delivere the reversible discharge capacity of 55.2 mAh · g-1 at 0.1 C after 50 cycles;meanwhile,phenylalanine-based anode also display good cycle stability and rate performances,indicating good feasibility of organic phenylalanine anode in lithium ion battery. |
