Abstract

Supercapacitors can be useful in many fields of modern technology due to their high energy storage capacity and fast charge-discharge cycle. It is replacing conventional electrical energy storage devices such as capacitors and batteries. The supercapacitor electrodes are efficient for sustainable energy storage and conversions due to their long lifespan and high cyclic rate. Recently, supercapacitors are used in every field of technology like transportation, consumer electronics, electrical instruments, wearable and portable devices, etc. Cobalt hydroxide thin films were prepared by the electrochemical deposition of CoCl2, Co(NO3)2, and Co(OAc)2 onto stainless steel (SS) substrate. The cobalt-based chemical compounds of 0.1M electrolyte solution is prepared in 100ml double distilled water at room temperature. Further, structural, morphological and capacitive properties were studied. In addition, the electrochemical characteristics of the obtained cobalt hydroxide thin films were determined experimentally to predict their application efficiency in advanced energy storage devices such as supercapacitors.
