Electrochemical Characteristics of Expanded Graphite by Microwave Irradiation in Lithium Ion Battery

리튬 이온 커패시터에서 마이크로파 조사에 의한 팽창 흑연의 전기화학적 특성

Graphite is used as a negative electrode active material of Lithium ion capacitor (LIC). At the cathod, electrostatic reaction of EDLC is a very high reaction rate compared to a oxidaion reduction reaction. When the graphite was expanded that the length between the sheet, the intercalation of lithium ions is smoothed. And thus, the power density increases. By measuring the XRD, it was confirmed that the increase in interlayer spacing of graphite. And by measuring an electrochemical reactionin Lithium Ion Battery (LIB), it was confirmed the tendency of power density is improved.
