제목 Fabrication Porous Carbon Derived from PVCD-g-PMMA to Increase EDLC Electrochemical performance with Non-aqueous Electrolyte
초록 There are two type of supercapacitor; one is electrochemical double-layer capacitors (EDLCs), and the other is pseudo-capacitors. Because EDLC charges and discharges charges on the surface of electrodes, the size of the non-surface area and pores are one of the indicators of performance comparison to improve the performance of EDLC. In electrode materials, we replaced activated carbon to porous carbon derived from PVDC-g-PMMA (pc-PP). The pc-PP can make PP through NaOH and activation. The process of activation produces chemical activation by carbonizing the PP at 600 ℃ and then applying heat at 850 ℃ degrees with NaOH. We used pc-PP fabricated to button type EDLC with non-aqueous electrolyte TEABF4/PC. The characterizations of pc-PP were checked morphology, crystallinity, and structure by field emission scanning electron microscopes (FE-SEM), Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), and Raman spectroscopy. Although fabricated symmetric supercapacitor confirmed electrochemical performance by cyclic voltammetry (CV), galvanostatic charge/discharge (GCD), electrochemical impedance spectroscopy (EIS), and calculate capacitance.
