Vanadium Oxide Aerogel Electrode Materials

摘要

This research consists of two studies related to the incorporation of vanadium oxide aerogels in electrode structures for secondary lithium batteries. A common theme in this work is that the electrode structures retain their interconnected mesoporous morphology so that there is electrolyte access to the solid oxide phase. One series of experiments is directed at creating a nanocomposite electrode based on combining carbon nanotubes with vanadium oxide aerogels. Excellent results are observed, particularly at high discharge rates. The second study involves the development of electrode fabrication methods, with the objective of increasing electrode loading. Specific capacities in excess of 350 mAh/g are obtained with electrodes containing 10 mg/sq cm.
