Hybrid carbon nanostructure assemblage for high performance pseudo-capacitors

Hybrid nanostructured materials for high-performance electrochemical capacitors

The hybrid nanostructure of MnCo2O4.5 nanoneedle/carbon aerogel for symmetric supercapacitors with high energy density.

Current applications of carbon-based supercapacitors are limited by their low energy density. One promising strategy to enhance the energy density is to couple metal oxides with carbon materials. In this study, a porous MnCo2O4.5 nanoneedle/carbon aerogel hybrid nanostructure was synthesized by assembling MnCo2O4.5 nanoneedle arrays on the surface of channel walls of hierarchical porous carbon ...

Silicon Interposers enable high performance capacitors

©ALLVIA, Inc. 2011 Sunnyvale, CA www.allvia.com Page 1 Interposers between ICs and package substrates that contain thin film capacitors have been used previously in order to improve circuit performance. However, with the interconnect inductance due to wire bonds being high, the benefits of thin film capacitors have not been fully realized. Replacing the wire bonds with Through Silicon Vias (TSV...

Single-walled carbon nanotube probes for high-resolution nanostructure imaging

Single-walled carbon nanotube ~SWNT! tips have been used to image nanostructures with high resolution. Studies of gold nanocrystal standards showed that SWNT tips provide a significant improvement in lateral resolution with respect to multi-walled nanotube tips and microfabricated Si tips. The nanotube tips were also used to resolve substructure within SWNTs deposited on surfaces. These results...

Architecture Analysis of High Performance Capacitors (postprint)

Evolutionary increases in the demand on electrical power systems have resulted in the need to develop the next generation of compact, power dense, electrical systems utilizing robust and efficient high voltage power devices that are operable over an extended temperature range (-55°C to 250°C). In particular, there is a need to investigate novel capacitive architectures as a means to compliment ...
