Abstract Scope |
Capacitors based in ferroelectric BaTiO3 are ubiquitous in electronic applications for filtering and decoupling. Ceramic dielectric capacitors are also emerging as serious contenders for pulsed power applications due to their high-power densities and fast charge-discharge rates. Nonetheless, they still suffer from limited energy storage densities. Novel ferroic systems exhibiting high power density combined with an energy storage density greater than 15 J/cm3 have been recently developed. The mechanisms underpinning this record value of energy storage density have been investigated using a combination of diffraction, electron microscopy and polarisation measurements. The results will be presented and discussed alongside effective designing strategies to enhance energy storage in ferroic ceramics for sustainable development. |
