6 FAQs about [Super energy storage ceramics]
Are KNN-based ceramics suitable for energy storage applications?
Although a large amount of KNN-based ceramics with high recoverable energy storage density (Wrec) have been designed for energy storage applications, the relatively low energy storage efficiency (η) limits their further development.
What is a high recoverable energy storage density (WREC)?
A high recoverable energy storage density (Wrec), efficiency (η), and improved temperature stability are hot topics to estimate the industrial applicability of ceramic materials. A large maximum polarization (Pmax), low remnant polarization (Pr), and high breakdown field (Eb) are sought after to attain a greater Wrec and η.
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.
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.
Do dielectric ceramics have a high entropy strategy?
Dielectric ceramics are widely used in advanced high/pulsed power capacitors. Here, the authors propose a high-entropy strategy to design “local polymorphic distortion” in lead-free ceramics, achieving high energy storage performance.
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).
