High-rate electrochemical capacitors based on ordered mesoporous silicon carbide-derived carbon.
Microporous carbons, produced by selective etching of metal carbides in a chlorine-containing environment, offer narrow distribution of micropores and one of the highest specific capacitances reported when used in electrical double layer capacitors (EDLC) with organic electrolytes. Previously, the small micropores in these carbons served as an impediment to ion transport and limited the power s...
متن کاملMonolithic carbide-derived carbon films for micro-supercapacitors.
Microbatteries with dimensions of tens to hundreds of micrometers that are produced by common microfabrication techniques are poised to provide integration of power sources onto electronic devices, but they still suffer from poor cycle lifetime, as well as power and temperature range of operation issues that are alleviated with the use of supercapacitors. There have been a few reports on thin-f...
متن کاملOrdered mesoporous silicon carbide (OM-SiC) via polymer precursor nanocasting.
Ordered mesoporous SiC with high specific surface area (650-800 m(2) g(-1)) and well ordered pore structure was obtained via nanocasting of polycarbosilanes into SBA-15 and subsequent conversion of the polymer at 1300 degrees C.

متن کاملAdditive-Driven Self-Assembly of Well-Ordered Mesoporous Carbon/ Iron Oxide Nanoparticle Composites for Supercapacitors
Ordered mesoporous carbon/iron oxide composites were prepared by cooperative self-assembly of poly(tbutyl acrylate)-block-polyacrylonitrile (PtBA-b-PAN), which contains both a carbon precursor block and a porogen block, and phenol-functionalized iron oxide nanoparticles (NPs). Because of the selective hydrogen bonding between the phenol-functionalized iron oxide NPs and PAN, the NPs were prefer...
