CoCO3 from one-step micro-emulsion method as electrode materials for Faradaic capacitors

Abstract Faradaic capacitor (FC) has been widely investigated during the past few decades, and dozens of prototypes have been proposed. However, it has not reached its full potential. In this work, we demonstrate a kind of FC comprising of a CoCO3 electrode. Synthesized through a micro-emulsion rout...
