2_04i/2014Inside Cover: Supercapacitors Based on Flexible Substrates: An Overview (Energy Technol. 4/2014)

Flexible Supercapacitors: The Inside Cover picture illustrates flexible supercapacitors made with several different substrate types for which flexibility and mechanical stability are of the utmost importance. These devices can provide electrical energy to flexible, wearable, and lightweight electronics for portable applications. In the Review by Won Bae Kim, Rudolf Holze, and co-workers at Gwangju Institute of Science and Technology and Technische Universität Chemnitz on page 325, the authors review the basic principles of flexible supercapacitors and the latest research advances that are moving this field forward. In particular, recent progress on flexible supercapacitor electrodes is reviewed with respect to bendable substrates, and their properties are discussed in detail.
