Description

Highlights: • Hydrothermal deposition of CoWO4 and CNT-CoWO4 nanocomposite on carbon cloth substrate. • Substantial increase in specific capacitance from the previously reported values. Highest till date. • Increase in potential window of the electrode from 0.6 V (CoWO4) to 1 V (CNT-CoWO4). • Fabrication of symmetric device exhibiting a potential window of 1.5 V.
