Abstract Scope |
The combination of lithium-ion batteries and supercapacitors makes lithium-ion capacitors (LICs) the ideal energy storage device for commercial applications. LIC exhibits the collective properties of the battery (high-energy density) and the supercapacitor (high-power density). In this work, a composite material with the unique architecture of graphene oxide (GO) encapsulation on the MnO2 nanorods is fabricated as an anode for LIC. The MnO2/GO composite electrode is fabricated using a hydrothermal method. Detailed electrochemical analysis reveals the superior charge storage ability of the composite electrode. In the half-cell configuration, the composite electrode exhibits a high initial discharge capacity of 1300 mAh/g at 0.2 C current density. A superior rate capability is obtained as the composite electrode holds a high discharge capacity of 1100, 900, 700, 300 mAh/g at the current density of 0.5, 0.7, 1, and 2 C, respectively. The LIC fabricated using the MnO2/GO composite anode demonstrates superior electrochemical performance. |
