Abstract
Nanoflake bismuth ferrite thin film was synthesized by means of electrodeposition technique at room temperature. The morphology and phase evaluation of the synthesized electrode were analyzed using scanning electron microscopy, X-ray diffraction, Raman spectroscopy, and surface wettability techniques. Specifically, the bismuth ferrite nanoflake electrode exhibited high specific capacitance of 72.2 F g−1 at a current density of 1 A g−1, and high rate capability with 37 % retention of capacitance even up to 20A g−1, and excellent cycling stability with 82.8 % retention of the initial capacitance after 1500 charge/discharge cycles, supporting that the bismuth ferrite thin-film electrode could be a potential candidate for supercapacitor application.
Highlights
Now-a-days, fast-growing market for portable electronic devices such as mobile phones, laptops, notebook computers, uninterruptible power supply, and the development of hybrid electric vehicles, etc., is increasing and there is an urgent demand for environmental-friendly high-power energy storage resources
Secondary BiFeO3 phase of BFO was noticed at 600 °C due to occurrence of (012), (202), (113), (104), (300), (312) peaks (JCPDS Card no. 20-0169) in X-ray diffraction (XRD) pattern
We have demonstrated a simple and economical electrodeposition process to synthesize bismuth ferrite (BFO) for supercapacitor application
Summary
Now-a-days, fast-growing market for portable electronic devices such as mobile phones, laptops, notebook computers, uninterruptible power supply, and the development of hybrid electric vehicles, etc., is increasing and there is an urgent demand for environmental-friendly high-power energy storage resources. BFO structures of mixed phases were synthesized onto conducting substrate using electrodeposition technique at room temperature.
