How do we evaluate the energy-storage performance of ceramics?

To evaluate the overall energy-storage performance of these ceramics, we measured the unipolar P - E loops of these ceramics at their characteristic breakdown strength (Fig. 3E and fig. S13) and calculated the discharged energy densities Ue and energy-storage efficiency η (Fig. 3F and fig. S14).

Which BNT-St ceramics are used for energy storage?

A Wrec (2.49 J/cm 3) with medium high η (85%) is obtained in NaNbO 3 modified BNT-ST ceramics , while a Wrec (2.25 J/cm 3) with moderate η (75.88%) in AgNbO 3 modified one . Meanwhile, BiAlO 3, BaSnO 3, and Bi 0.5 Li 0.5 TiO 3 -doped BNT-ST ceramics are also investigated for energy storage applications [, , ].

Does lead-free bulk ceramics have ultrahigh energy storage density?

Significantly, the ultrahigh comprehensive performance (Wrec ~10.06 J cm −3 with η ~90.8%) is realized in lead-free bulk ceramics, showing that the bottleneck of ultrahigh energy storage density (Wrec ≥ 10 J cm −3) with ultrahigh efficiency (η ≥ 90%) simultaneously in lead-free bulk ceramics has been broken through.

What is the research and development of BNT-based energy storage ceramics?

The energy storage research of BNT-based ceramics is summarized from three aspects: bulk, thin film and multilayer. The energy storage optimization of BNT-based ceramics is reviewed from ion doping and multi-component modification aspects. The future research and development of BNT-based energy storage ceramics are prospected.

Can dielectric ceramics be used in advanced energy storage applications?

This work opens up an effective avenue to design dielectric materials with ultrahigh comprehensive energy storage performance to meet the demanding requirements of advanced energy storage applications. Dielectric ceramics are widely used in advanced high/pulsed power capacitors.

Which lead-free ceramic systems have the best energy storage properties?

Further breakthroughs in energy storage properties were also achieved in other representative lead-free ceramic systems, such as the excellent Wrec values of 7.4, 8.2, and 12.2 J cm −3 in (K,Na)NbO 3 (KNN), BiFeO 3 (BF), and NaNbO 3 (NN)-based systems, respectively 7, 8, 9.
