/ Manufacturing method of Pitch-based Activated Carbon / Tube Shaped Polypyrrole Composite Electrode Material for Supercapacitor

摘要

The present invention relates to a method to manufacture an activated carbon/tube-shaped polypyrole composite electrode material based on pitch for a supercapacitor, which is able to improve an electrochemical performance to be used in eco-friendly storage of energy. According to the present invention, the method comprises: a step of mixing pyrole with methyl orange (MO) and Iron (III) chloride hexahydrate (FeCl32O) to manufacture a polypyrole; a step of mixing activated carbon with sodium dodecyl sulfate (SDS) to manufacture a mixture; a step of synthesizing the polypyrole with the mixture; and a step of washing and drying the synthesized mixture. As such, according to the present invention, the electrode material for the supercapacitor has a large capacity and an excellent discharge characteristic, and the supercapacitor including the electrode and a lithium secondary battery are able to realize a superior capacitance, life characteristics, and stability.
