Název v původním jazyce

SPS prepared NN-24SBT lead-free relaxor-antiferroelectric ceramics with ultrahigh energy-storage density and efficiency

Popis výsledku v původním jazyce

Dielectric ceramics are of great potential to be applied in electronic systems due to their fast discharge speed and temperature tolerance. However, the low energy storage density and efficiency highly restricts the applications of dielectric ceramics. Here, we propose a strategy of fine grain and highly densified relaxor-antiferroelectric (RE-AFE) ceramics to both increase the energy storage density and efficiency. We fabricated NaNbO3 based relaxor-antiferroelectric (RE-AFE) ceramics by Spark Plasma Sintering (SPS) and obtained an ultra-high recoverable energy storage density of 12.2 J/cm(3) and satisfied efficiency of 88%. The present research offers a route for designing dielectric ceramics with enhanced energy storage density and efficiency, which is significant to the application of dielectric ceramics.
