Energy storage density of ceramic capacitor system
Benefiting from the synergistic effects, we achieved a high energy density of 20.8 joules per cubic centimeter with an ultrahigh efficiency of 97.5% in the MLCCs. This approach should be universally applicable to designing high-performance dielectrics for energy storage and other related functionalities.

The KNN-H ceramic exhibits excellent comprehensive energy storage properties with giant Wrec, ultrahigh η, large Hv, good temperature/frequency/cycling stability, and superior.
Here, we present the principles of energy storage performance in ceramic capacitors, including an introduction to electrostatic capacitors, key parameters for evaluating energy storage properties, microstructural considerations, and critical electrical factors.
Dielectric ceramic capacitors are fundamental energy storage components in advanced electronics and electric power systems owing to their high power density and ultrafast charge and discharge rate. However, simultaneously achieving high energy storage density, high efficiency and excellent temperature stabil.
Herein, we design a high configurational entropy (HCE) material BaTiO3 -BiFeO 3 -CaTiO 3 with rational microstructural engineering that demonstrates an ultrahigh energy density of 7.2 J cm−3. The HCE design leads to the increased solubility of CaTiO 3 in the matrix, which enhances the resistivity and polarization.
