在本研究中，对甲苯磺酸钠（TsONa）掺杂聚吡咯（PPy）的锂离子电池负极通过一步简单的电聚合在铁箔上合成。用扫描电子显微镜、能量色散X射线光谱、傅里叶变换红外光谱和恒电流充放电分析研究了所获得的TsONa-PPy-Fe复合电极。正如预期的那样，形成了许多不规则的TsONa掺杂的PPy微球颗粒，并与Fe箔表面紧密结合。此外，所制备的TsONa-PPy-Fe阳极也具有良好的电化学性能。例如，即使在至少50次循环之后，可逆容量仍然为约105-115 mAh/g。PPy的高储锂活性和TsONa掺杂的PPy的高导电性共同促成了令人满意的电化学性能。© 2017威利期刊公司.

In this study,p‐toluene sulfonate (TsONa) doped polypyrrole (PPy) was synthesized for an anode in a lithium‐ion battery via a one‐step facile electropolymerization on Fe foil. The obtained TsONa–PPy–Fe composite electrode was investigated with scanning electron microscopy, energy‐dispersive X‐ray spectroscopy, Fourier transform infrared spectroscopy, and galvanostatic charge–discharge profiling. As expected, many irregular microspherical particles of TsONa‐doped PPy formed and combined tightly with the surface of Fe foil. Furthermore, the obtained TsONa–PPy–Fe anode also delivered satisfactory electrochemical performances. For example, the reversible capacity was still about 105–115 mAh/g, even after at least 50 cycles. The high lithium storage activity of PPy and the high conductivity of the TsONa‐doped PPy jointly contributed into the satisfactory electrochemical performances. © 2017 Wiley Periodicals, Inc. J.
