Special Issue Information

Dear Colleagues,

We are pleased to invite you to submit your work to this Special Issue “High-Performance Dielectric Ceramic Films and Coatings for Energy Storage Capacitors”.

Dielectric ceramics films and coatings with high permittivity and high breakdown strength are required for applications including high-charge capacitors and energy storage devices, where dielectric composites could find their position as potential candidates. As one important part of the family, dielectric ceramics for energy storage capacitors are widely used in both civil and military applications and are especially suitable for pulsed power capacitors due to their high power densities and fast discharge rates. With the increasing demand for lightweight, miniaturized and compact electronic devices, the research on dielectric materials with high-energy-storage performance has attracted more and more attention.

This Special Issue aims to discuss and present significant new findings related to the synthesis, fabrication, structure, properties, performance, and technological application, in addition to the strategies and policies, of dielectric ceramics for energy storage capacitors and their devices for sustainable energy and development. Papers that have high scientific and technological merit, impart important new knowledge and are of high interest to the international community will be published.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but not limited to) the following:

  • Ceramic powders;
  • Composite ceramic materials;
  • Dielectric ceramic films;
  • Dielectric ceramic coatings;
  • Glass ceramics;
  • Ceramic–polymer dielectric materials;
  • Special structures of dielectric materials;
  • Interface effects of dielectrics;
  • Characterization techniques for ceramics.

We look forward to receiving your contributions.

To address the worsening energy crisis from rapid fossil fuel consumption, this study synthesized Ce-FeWO4 composites and hydrophilic carbon nanotubes. XRD and other characterizations showed all intermediates had rough, porous nanosheet morphology; Ce-doping formed disordered porous structure in FeWO4, increasing its specific surface area. Three-electrode tests confirmed optimal parameters: 0.5% Ce-doping and 12 h growth. Ce-FeWO4 exhibited a specific capacity of 1875 ± 28 F/g at 1 A/g (based on five parallel samples), and retained 1807 F/g after 3000 cycles (exceeding previous studies) with excellent stability. The Ce-FeWO4//CNTs asymmetric supercapacitor achieved 152 F/g specific capacity, 81.4 Wh/g energy density, and 768 W/kg power density. The simple, efficient, eco-friendly preparation process and the material’s high capacitance and stability offer broad application prospects in the electrode field. Full article

In order to improve the output performance of multi-chamber piezoelectric pumps, this paper proposes a novel design for a four-chamber series–parallel piezoelectric pump, based on the characteristics that the parallel chamber structure significantly increases the output flow rate, and the series chamber structure effectively improves the output pressure. The theoretical output flow rate and pressure of the four-chamber series–parallel piezoelectric pump were calculated, and a prototype was fabricated. Tests were conducted to compare the liquid transport performance of piezoelectric pumps with three different structures: series, parallel, and series–parallel. The results show that, when transporting liquid, the output flow rate of the four-chamber series–parallel structure increased by up to 13.3% compared to the four-chamber series structure, reaching a maximum of 767 mL/min. Additionally, the maximum output pressure of the series–parallel structure increased by 43.4% compared to the four-chamber parallel structure, reaching 42.3 kPa. The four-chamber series–parallel design combines the advantages of both series and parallel configurations, improving the output performance of the piezoelectric pump and providing a reference for the structural design of multi-chamber piezoelectric pumps.
