Green and facile synthesis of nanosized polythiophene as an organic anode for high-performance potassium-ion battery

摘要

In this work, nanosized polythiophene (PTh) is synthesized via a green and facile method. The obtained nanosized PTh was characterized by Fourier transform infrared (FTIR), X-ray diffraction (XRD), Brunauer-Emmett-Teller theory (BET) and scanning electron microscopy (SEM). The result indicated that a nanosized, porous and amorphous PTh was synthesized. As an organic anode material for potassium ion battery, the PTh shows excellent performance with a reversible capacity of 58 mAh g(-1) at 30 mA g(-1).
