α-Fe2O3@PANI Core–Shell Nanowire Arrays as Negative Electrodes for Asymmetric Supercapacitors
Abstract
Highly ordered three-dimensional α-Fe2O3@PANI core-shell nanowire arrays with enhanced specific areal capacity and rate performance are fabricated by a simple and cost-effective electrodeposition method. The α-Fe2O3@PANI core-shell nanowire arrays provide a large reaction surface area, fast ion and electron transfer, and good structure stability, which all are beneficial for improving the electrochemical performance. Here, high-performance asymmetric supercapacitors (ASCs) are designed using α-Fe2O3@PANI core-shell nanowire arrays as anode and PANI nanorods grown on carbon cloth as cathode, and they display a high volumetric capacitance of 2.02 mF/cm3 based on the volume of device, a high energy density of 0.35 mWh/cm3 at a power density of 120.51 mW/cm3, and very good cycling stability with capacitance retention of 95.77% after 10,000 cycles. These findings will promote the application of α-Fe2O3@PANI core-shell nanowire arrays as advanced negative electrodes for ASCs.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
