WORK PACKAGE 8
The aim of this work package is to characterize rhenium compounds regarding their perspective application in symmetric hybrid supercapacitors composed of porous matrix with embedded rhenium species. Metal particles are very attractive active species that are able to increase capacitance by faradaic processes, resulting from oxidation/reduction reaction of metal ion with electrolyte.
The combination of rhenium with i.e. nickel, cobalt, zinc, bismuth and other proposed in this project metals may be perspective and have synergistic effect on the electrode performance. Non-ferrous metals play a big role in energy storage materials and are responsible for a significant increase in specific capacitance of lithium-ion batteries and supercapacitors.
Rhenium compounds obtained in this project will be thoroughly examined using potentiostatic and galvanostatic techniques. Based on the electrochemical evaluation the most electrochemically active compounds will be selected and used as components in hybrid-type electrode preparation.
