New Developments in Ultracapacitor Technology.
Abstract
The objective of this in-house research project is to develop new high surface area (HSA) electrodes suitable for use as primary internal components of ultracapacitors. Ultracapacitors are low voltage charge storage devices that do not involve chemical reactions to store or release energy; instead, planar HSA electrodes are employed to hold charge across a thin layer of electrolyte. In the past, ultracapacitor development has relied heavily upon use of exotic electrode materials (i.e., platinum group metal oxides) which are stable in aqueous sulfuric acid electrolyte. Ultracapacitor availability has been hindered by the lack of more common substitute electrode materials, such as HSA molybdenum nitride, which possess adequate electronic conductivity and also offer equivalent long term compatibility with the electrolyte.
