Abstract

original image

A study by S. Yoon, J. Lee, and co-workers on the improvement of rate performance highlights an important issue for pseudocapacitor electrode materials. On page 3747, the synthesis of an ordered mesoporous tungsten oxide–carbon nanocomposite is presented via a ‘one-pot’ soft-template method. The ordered mesoporous structure, partial reduction of the metal oxide, and the nanosized mixing of the metal oxide/carbon result in both high power and energy density.
