Energy Storage Performance of PbZrO3-Based Antiferroelectric Ceramics
Prof. Tongqing Yang Functional Materials Research Laboratory, School of Materials Science and Engineering Tongji University, Shanghai, China
The excellent energy-storage performance of antiferrolelectric ceramic capacitors, such as high-power density, fast discharge speed, and the ability to operate over a broad temperature range, gives rise to their wide applications in different energy-storage devices.
In this talk, I will first introduce the research status of antiferroelectric ceramics in China briefly. Then, I will introduce some of our recent works we did and are doing in my group, including lead-based (PbZrO3, PbHfO3) and lead free (AgNbO3)-based antiferroelectric ceramics, and how to improve their energy-storage density by tailoring the composition and phase transition electric field. In last, I will discuss some of my ideas about the value of energy-storage density of antiferroelectric ceramics obtained in different methods.
About the FLAME-inars
The FLAME-inars are organized by the collaborative project FLAME at TU Darmstadt, in which electronic-structure-property relationships are being developed and exploited to realize novel lead-free antiferroelectric compounds. The seminars will gather experts in processing, characterization and theory to discuss materials and applications, bulk and thin films, fundamental properties, electronic structure & defects, and related aspects.
