Abstract
Vanadium oxides are anticipated to be high-performance energy storage electrodes due to their connected double layer and pseudo-capacitive charge storage mechanism. In the current work, flexible stainless-steel mesh substrates are created using a straightforward hydrothermal approach resulting net-like linked nanoflakes and microflowers. There are more electrochemically active sites for energy storage due to its large surface area. Stainless-steel mesh substrates themselves provide porous structure for charge transfer. Morphological results of SEM show porous nanoflake-like structures grown on the substrate. Phase is confirmed using XRD studies. It shows the specific capacitance of 675.66 F g−1 and 343.33 Wh g−1 of energy density at 0.002 A g−1 current density and power density of 19,000 W g−1.
期刊介绍:
The Bulletin of Materials Science is a bi-monthly journal being published by the Indian Academy of Sciences in collaboration with the Materials Research Society of India and the Indian National Science Academy. The journal publishes original research articles, review articles and rapid communications in all areas of materials science. The journal also publishes from time to time important Conference Symposia/ Proceedings which are of interest to materials scientists. It has an International Advisory Editorial Board and an Editorial Committee. The Bulletin accords high importance to the quality of articles published and to keep at a minimum the processing time of papers submitted for publication.
