  text: We report on synthesis of highly crystalline polythiophene and its application
    in supercapacitor electrodes. The material exhibits a remarkably stable electrochemical
    behavior and an excellent device performance. The device delivers an electrode
    specific capacitance (Csp) of 129.13F g−1, Cell Csp of 32.28F g−1 at 0.5 A/g;
    energy, and power densities of ∼ 3 Wh kg−1 and 250 W kg -1, respectively at 0.5
    A/g. Also, it exhibits an excellent retention of Cell Csp and coulombic efficiency
    up to ∼ 95 % over 10,000 continuous galvanostatic charge discharge (GCD) cycles
    indicating a remarkable performance by a standalone, pristine and undoped polythiophene.
    Electrochemical impedance spectroscopy (EIS) studies further suggest material’s
    stable capacitive behavior. The material’s enhanced electrochemical properties,
    stable behavior and outstanding performance in device application are attributed
    to the crystalline phases present in the polymer matrix achievable via a slow
    rate of synthesis; overall, an edge over other conventional synthesis methods.
