CARBON AEROGELS FOR ELECTROCHEMICAL APPLICATIONS

A major advantage of highly crosslinked, organic aerogels is the abili ty to transform many of these materials into electrically conductive c arbon aerogels. Carbon aerogels have been formed as monoliths, microsp heres, irregularly-shaped powders. and thin film composites. In all ca ses, the carbon aerogels retain their high surface area (400-800 m2/g) and ultrafine cell/pore size (<100 nm). Carbon aerogels are bring exa mined as electrodes for double lever capacitors, pseudocapacitors, and capacitive deionization units. This paper examines the synthesis, str ucture-property relationships, and performance of carbon aerogel elect rodes used in electrochemical applications. (C) 1998 Elsevier Science B.V.
