In this study, we selected an appropriate crystallization temperature (750 °C) to obtain glass-ceramics with the excellent hardness and energy storage properties. Besides, increasing the dielectric breakdown strength (DBS) increases along with the crystallization temperature was owing to the dense microstructure. Consequently, the good energy properties, including a high energy efficiency of 89.79% with a high recoverable energy density of 1.74 J/cm3can be achieved in the sample crystallized at 750 °C for 2 h. More significantly, the corresponding hardness of the energy storage glass-ceramics has not been reported before. These results demonstrate that the prepared sample has promise use in the dielectric capacitors field.

“…These results indicate that BNN-AB glass-ceramic is a potential candidate for dielectric energy storage. 11 The perovskite-structured Sr 0.7 Bi 0.2 TiO 3 materials is an example of a typical form of relaxor ferroelectric. Relaxor behavior is induced due to the vacancy of the Sr site and the Bi 3+ ion being off-centered.…”

In the present study, Sr0.7Bi0.2TiO3 is mixed with [(K0.5Bi0.5)(Mg1/3Nb2/3)O3] to form a solid solution of [(1 − x)SBT–x(KB)(MNb), x = 0.02, 0.04, 0.06, 0.1]. From the XRD results, it is indicated that KB is the main substituent for SBT ceramic at the A‐site. The breakdown strength (BDS) of ceramic gradually increases with an increase in doping content and achieves a high value of 280 kV/cm for x = 0.06. In addition, the 0.94SBT–0.06(KB)(MNb) ceramic shows excellent temperature stability (−55 to 140°C), a high recoverable energy density (Wd)—2.6 J/cm3, and an efficiency (η)—88% at 280 kV/cm. Therefore, 0.94SBT–0.06(KB)(MNb) ceramic is one of the possible materials for energy storage capacitor applications.

“…This indicates that electric field assisted crystallization is an effective method to enhance the energy storage density and efficiency simultaneously by modulating defect formation to alleviate interfacial polarization in the BTAS glass ceramics. The optimum electric field strengths applied during crystallization, namely 2 and 3 kV cm −1 , can achieve much better energy storage densities with high efficiencies of 10.36 J cm −3 with 85.8% and 12.04 J cm −3 with 81.1%, respectively, which represents a very strong energy storage performance compared to many dielectric ceramics so far reported, such as KNN‐based ceramics, [ 52 , 53 , 54 , 55 , 56 ] BFO‐based ceramics, [ 57 , 58 , 59 , 60 , 61 ] BT‐based ceramics, [ 62 , 63 , 64 , 65 , 66 , 67 ] and other glass ceramics, [ 68 , 69 , 70 , 71 , 72 ] as shown in Figure 4d .…”

Along with the demand for further miniaturization of high and pulsed power devices, it becomes more and more important to realize ultrahigh recoverable energy storage density (Wrec) with high energy storage efficiency (η) and ultrahigh discharge energy storage density (Wd) accompanied by high power density (Pd) in dielectrics. To date, it remains, however, a big challenge to achieve high Wrec or Wd in glass ceramics compared to other dielectric energy storage materials. Herein, a strategy of defect formation modulation is applied to form “amorphous‐disordered‐ordered” microstructure in BaTiO3‐based glass ceramics so as to achieve a high Wrec of 12.04 J cm−3 with a high η of 81.1% and an ultrahigh Wd of 11.98 J cm−3 with a superb Pd of 973 MW cm−3. This work demonstrates a feasible route to obtain glass ceramics with an outstanding energy storage performance and proves the enormous potential of glass ceramics in high and pulsed power applications.
