Flexible Electronics: Sub‐Micrometer‐Thick All‐Solid‐State Supercapacitors with High Power and Energy Densities (Adv. Mater. 35/2011)

Flexible, all-solid-state supercapacitors with sub-micrometer thickness are reported by Yi Ding and co-workers on page 4098. This power source, which is based on a unique nanoporous gold/polypyrrole (NPG-PPy) hybrid nanostructure, demonstrates high volumetric capacitance as well as high power and energy densities, suggesting its potential in powering next-generation wearable and miniaturized electronic devices.
