A high dielectric composite for energy storage application

Autor: K. Benkhouja, Christian Courtois, Mohamed Rguiti, S. Aboubakr, Abdelowahed Hajjaji

Publikováno v: International Journal of Hydrogen Energy. 42:19504-19511

Piezoelectric composites are widely studied due to their good performances. Several kinds of these composites have been developed for sensing and actuation applications, however, most of them are not used for energy storage devices, because of their

Optimization and improvement of energy storage efficiency in a flexible dielectric capacitor

Autor: S. Aboubakr, Christian Courtois, K. Benkhouja, Abdelowahed Hajjaji, Mohamed Rguiti

Publikováno v: 2016 International Renewable and Sustainable Energy Conference (IRSEC).

Capacitors which are dedicated to microelectronic applications require a lot of characteristics. Indeed they should have a high capacitance but shaped in small sizes, moreover, for some specific applications those capacitors should be flexible to be
