This manuscript explores the diverse and evolving landscape of advanced ceramics in energy storage applications. With a focus on addressing the pressing demands of energy storage technologies, the article encompasses an analysis of various types of advanced ceramics utilized in batteries, supercapacitors, and other emerging energy storage systems.
Ceramics possess excellent thermal stability and can withstand high temperatures without degradation. This property makes them suitable for high-temperature energy storage applications, such as molten salt thermal energy storage systems used in concentrated solar power (CSP) plants .
Stability is essential for dielectric capacitors under distinguished working environments, which can determine the longevity of energy storage devices. In particular, the temperature has a severe impact on the performances of energy storage ceramics.
Nanoceramics, which consist of ceramic nanoparticles or nanocomposites, can offer unique properties that are advantageous for energy storage applications. For instance, nanoceramic materials can exhibit improved mechanical strength, enhanced surface area, and tailored electrical or thermal properties compared to their bulk counterparts .
Often, in the practical application fields, the frequency and thermal stability of energy storage performances for dielectric ceramic capacitors are deemed as one of the most vital criteria for measuring the quality of materials.
These properties severely restrict the energy storage capabilities of KNN-based ceramics. For the sake of enhancing the energy storage properties of KNN-based ceramics, the multi-component optimization strategy is conducted by doping Li +, Bi (Ni 1/2 Zr 1/2)O 3 (BNZ) and NaNbO 3 (NN) [Fig. 1 (b)].
