Abstract :

Supercapacitors are considered one of the most prominent and efficient energy storage devices, next to lithium ion batteries
due to their high power densities, fast charge-discharge capabilities and long cyclibility. Supercapacitors possess high
power density in compare to batteries and are able to solve the increasing demand for energy in small consumer products,
electrical vehicles and devices where quick power delivery is highly desired. We have used several facile methods to synthesized
nanostructured ceramics such as NiCo2O4, Fe3O3 and CoMoO4. The electrochemical properties of these metal oxides were
studied in details. It was observed that the charge-storage capacity depends on their morphology and electrolytes used. We
have fabricated flexible supercapacitor device by using these metal oxides. The device showed no degradation in the capacitive
properties on bending confirming their flexible nature. We have also studied the effect of temperature on the charge storage
capacity of the devices for high temperature applications. The specific capacitance of the device significantly increased when
the operational temperature of the device was elevatedfrom10 to 70oC. Hence, this work provides facile methods to synthesize
morphologies controlled metal oxides for applications in next generation flexible energy storage devices which could drive more
efficiently at higher temperature.
