1. Introduction Multilayer ceramic capacitors (MLCCs) are indispensable basic components in many types of electronic equipment, and function in filtering, direct current blocking, coupling, and decoupling in electronic circuits.
Throughout the frequency range of 1 to 100 Hz, Wrec and η consistently maintain high values, ranging from 5.8 to 6.0 J·cm −3 and 94.3% to 96.0%, respectively. Moreover, the assessment of ceramic capacitors for practical energy storage applications should also consider the charging and discharging performance, another crucial factor.
There are various types of ceramic materials that can be used to fabricate capacitors, while their dielectric properties are greatly different. In general, commercially available ceramic capacitor dielectrics are basically categorised into three classes . Class I dielectrics are usually considered as temperature-compensating ceramic materials.
