Abstract
A nanoporous insulating oxide composite electrode and ultracapacitor device, method of manufacture and method of use thereof. The composite electrode being constructed from a conductive backing electrode and an composite layer. Preferably, the ultracapacitor device is configured in a stacked, coiled or button cell configurations and includes composite electrodes. The composite layer being substantially free of mixed oxidation states and nanoporous and having a median pore diameter of 0.5-500 nanometers and average surface area of 300-600 m/g. The composite layer made from a stable sol-gel suspension containing particles of the insulating oxide, the median primary particle diameter being 1-50 nanometers. Preferably, the insulating oxide is AlO, MgAlO, SiOor TiO. Preferably, the backing electrode is carbon paper sputter-coated with a film of Au.
