FIU Electronic Theses and Dissertations
Hybridization of lithium-ion batteries (LIBs) and electrochemical capacitors (ECs) at electrode level can potentially provide high-performance capacitive energy storage having a good combination of high energy density, high power density, and moderate cycling longevity. Lithium-ion hybrid capacitor (LIHC) system consisting of a battery-type anode and a capacitor-type cathode represents an attractive hybridization approach aimed at bridging the performance gap between the two energy storage systems. The application of such energy storage system may extend the functionalities of many electronic devices.
In this dissertation, different LIHC configurations were designed and evaluated. An LIHC device comprising electrostatically sprayed reduced graphene oxide (rGO)-based …
