Presence of Nanoparticles in Efforts to Boost Lifetime of Super Capacitors

Tehran, Iran | Posted on January 20th, 2015

The method used in the production of the super capacitor is highly simple and fast.

In this research, zirconium oxide nanoparticles in addition to graphene and nanoporous black carbon were used to modify the performance of the bladders of the super capacitor electrode. The aim of the researchers was to study and find out the reasons for the reduction in the performance of the super capacitors. To this end, they studied the effect of the presence of nanoparticles and their arrangement and the effect of electrolyte ion on the performance of the electrode. The obtained results can help increase the lifetime of super capacitors. The mechanical pressing process was used in the production of the electrode as a fast and simple method.

A combination of zirconium oxide nanoparticles, graphene and nanoporous carbon black was used in this research to increase the specific area of the electrode. The designed super capacitor was evaluated through cycling voltammetry, electrochemical impedance spectroscopy and scanning tunneling microscopy methods.

Tests showed that zirconium oxide deposits on the electrode surface after being charged and discharged, and it results in a decrease in the specific area of the electrode. As a result, much less energy can be stored in the electrode.

Results of the research have been published in Materials Science in Semiconductor Processing, vol. 30, issue 1, 2015, pp. 625-630.
