Abstract
The final year of the project focussed on the development of new electrode materials with both double-layer and Faradaic capacitances, and demonstration of asymmetric supercapacitors containing such materials. The synthesis, characterization and electrochemistry of Ru oxide/carbon nanotube composites, anthraquinone modified carbon (AQ-C), dihydroxybenzene modified carbon (DHB-C), and fluorenone modified carbon are described. The performances of asymmetric supercapacitors with AQ-C negative electrodes and Ru oxide or DHD-C positive electrodes are reported. Previous results for Ru oxide, carbon fabric (CF), Ru oxide/CF composite, and AQ-C supercapacitors are reviewed. Results for all supercapacitors developed in the project are compared and evaluated against the project targets. Ru oxide and AQ-C/Ru oxide devices greatly exceed the targets and are identified as excellent candidates for further development.
