Nanoscaled ferroelectric (pseudo)-binary oxide thin film supercapacitors for flexible and ultrafast pulsed power electronics (NanOx4Estor)

Project Director: Dr. Corneliu GHICA


The current momentum in boosting the effective utilization of renewable energy resources determines an increased request for dielectric supercapacitors as vital electronic elements for the DC-to-AC conversion of the collected/stored electrical energy, especially for the advanced propulsion systems in aircraft and automotive industry. Unlike batteries, dielectric supercapacitors can release the stored energy in a microsecond scaled period of time to create intense power pulses. Materials selected for highly performing dielectric supercapacitors should meet a series of prerequisites in terms of dielectric properties, temperature stability, energy density, and charge-discharge efficiency. The mainstream capacitors currently employed in power inverters for hybrid electric vehicles use polymer dielectrics (e.g. BOPP) for which additional cooling systems are necessary in order to keep the ambient temperature below the maximum operating temperature of the polymeric material. NanOx4EStor focuses on the creation of supercapacitors based on (pseudo-)binary oxide thin films, with improved energy storage density and operating temperature for pulsed power applications.
