Preparation of Graphene Oxide/La(2)Ti(2)O(7) Composites with Enhanced Electrochemical Performances for Supercapacitors
[Image: see text] A series of graphene oxide (GO)/lanthanum titanate (La(2)Ti(2)O(7,) LTO) fiber composites were prepared through a hydrothermal method. The LTO fibers were homogeneously dispersed between the GO sheets. The structure and micromorphology of the GO/LTO composites were systematically s...

description | [Image: see text] A series of graphene oxide (GO)/lanthanum titanate (La(2)Ti(2)O(7,) LTO) fiber composites were prepared through a hydrothermal method. The LTO fibers were homogeneously dispersed between the GO sheets. The structure and micromorphology of the GO/LTO composites were systematically studied. The composite exhibited a high specific capacitance of 900.6 F g(–1) at a current density of 1 A g(–1) in the 1 M H(2)SO(4) and 10 wt % sucrose aqueous solution as the electrolyte. With the extended potential window of 1.8 V, the fabricated asymmetric supercapacitor device delivered a maximum energy density of 94.0 Wh kg(–1) at a power density of 750.1 W kg(–1). The GO/LTO composites could be promising materials for energy storage. |
