In this work, Pitch-based activated carbon/tubular polypyrrole (ACPPy) composites with various tubular polypyrrole(T-PPy) contents are prepared as active electrode materials for supercapacitors. Examination of the morphology of the ACPPy composites by scanning electron microscopy (SEM) and transmission electron microscopy (TEM) shows that T-PPy is deposited onto the surface of pitch-based activated carbons (ACs). The electrochemical performance of the prepared materials was characterized by cyclic voltammetry (CV) and galvanostatic charge/discharge (GCD) measurements using an IviumStat electrochemical workstation.
