Are electrostatic capacitors based on dielectrics suitable for energy storage?

Electrical energy storage technologies play a crucial role in advanced electronics and electrical power systems. Electrostatic capacitors based on dielectrics have emerged as promising candidates for energy storage applications because of their ultrafast charge-discharge capability and stability (1 – 3).

Who are the authors of electroceramics for high-energy density capacitors?

G. Wang, Z. Lu, Y. Li, L. Li, H. Ji, A. Feteira, D. Zhou, D. Wang, S. Zhang, I. M. Reaney, Electroceramics for high-energy density capacitors: Current status and future perspectives. Chem. Rev. 121, 6124–6172 (2021).

Can dendritic nanopolar insulators improve energy storage performance and stability?

We propose a microstructural strategy with dendritic nanopolar (DNP) regions self-assembled into an insulator, which simultaneously enhances breakdown strength and high-field polarizability and minimizes energy loss and thus markedly improves energy storage performance and stability.

Can self-assembled nanocomposite Fes regulate ferroelectricity and piezo electricity?

Recently, in self-assembled nanocomposite FEs (24 – 27), the formation of local heterogeneity with vertically aligned nanopillars (Fig. 1B) has demonstrated the potential of these materials for regulating ferroelectricity and piezoelectricity.
