چکیده
The cyclic performance of flexible free-standing graphene-Fe2O3 hybrid sheet is considerably improved and was fabricated by a novel one-step hydrothermal process. X-ray diffraction (XRD), photoelectron spectroscopy (XPS), thermogravimetric (TGA), scanning electron microscopy (SEM), transmission (TEM), electrochemical workstation are performed to characterize the microstructure sheet. At current density 200 mA·g?1, obtained product has high initial discharge capacity 1466 mAh·g?1. nanohybrids also exhibited reversible 765 mAh·g?1 Coulombic efficiency 99.8% after 100 cycles, which benefited from open 3D laminated nanostructure constructed layered graphene paper Fe2O3 nanoparticles. Therefore, composite excellent rate stability can be greatly extended as anode material lithium-ion batteries.

La2O3 hollow nanospheres for high performance lithium-ion rechargeable batteries.
An efficient and simple protocol for synthesis of novel La(2)O(3) hollow nanospheres of size about 30 ± 2 nm using polymeric micelles is reported. The La(2)O(3) hollow nanospheres exhibit high charge capacity and cycling performance in lithium-ion rechargeable batteries (LIBs), which was scrutinized for the first time among the rare-earth oxides.
متن کاملThe Effect of Crystal Face of Fe2O3 on the Electrochemical Performance for Lithium-ion Batteries
Fe2O3 nanorods exposing (001) and (010) plane as well as Fe2O3 nanosheets exposing (001) plane have been successfully synthesized. Fe2O3 nanosheets exhibit better cycle performance and rate capabilities than that of Fe2O3 nanorods. The discharge capacity of Fe2O3 nanosheets can stabilize at 865 mAh/g at the rate of 0.2 C (1C = 1000 mA/g) and 570 mAh/g at the rate of 1.2 C after 80 cycles, which...
متن کاملEnhanced electrochemical performance of a crosslinked polyaniline-coated graphene oxide-sulfur composite for rechargeable lithium-sulfur batteries
Due to the extraordinarily high theoretical capacity of sulfur (1675 mAh g 1), the lithiumesulfur (LieS) battery has been considered a promising candidate for future high-energy battery applications. LieS batteries, however, have suffered from limited cycle lives, mainly due to the formation of soluble polysulfides, which prevent the practical application of this attractive technology. The enca...

متن کاملGraphene/Fe2O3/SnO2 ternary nanocomposites as a high-performance anode for lithium ion batteries.
We report an rGO/Fe2O3/SnO2 ternary nanocomposite synthesized via homogeneous precipitation of Fe2O3 nanoparticles onto graphene oxide (GO) followed by reduction of GO with SnCl2. The reduction mechanism of GO with SnCl2 and the effects of reduction temperature and time were examined. Accompanying the reduction of GO, particles of SnO2 were deposited on the GO surface. In the graphene nanocompo...
