Metal oxide/hydroxide materials for electrochemical capacitors

Energy storage and conversion materials are the subject of increasing research focus due to increasing global demand for clean energy. Compared with Li-ion batteries, electrochemical capacitors exhibit faster charge−discharge characteristics, higher power density, and longer lifetimes, making them indispensable in many portable systems and hybrid electric vehicles. The main aim of this doctoral research was to develop high performance electrode materials for electrochemical capacitors with the potential to be further developed into practical applications in the future. Relatively easy, cost-effective and environmentally-friendly methods amenable to future industrial production were sought with regard to the fabrication of high performance electrode materials. Five novel works are reported in this doctoral thesis.
