Here, we analyze the influence of the existing chemical system and structure of lithium-ion battery on the energy density of lithium-ion battery, and summarizes the methods of improving the energy density of lithium-ion battery in the aspects of material preparation and battery structure design.. However, compared with other energy storage devices such as batteries and supercapacitors, the energy storage density of dielectric capacitors is low, which results in the huge system volume when applied in pulse systems. Therefore, to meet the needs of device miniaturization and integration. . Achieving high energy-storage density and efficiency in dielectric capacitors at low electric fields remains a critical challenge.

High energy storage density is required for the need of devices’ miniaturization and lightweight, since more energy can be stored when the volume is the same. An ideal energy storage dielectric should have large dielectric constant and high breakdown strength at the same time.
Scientific Reports 15, Article number: 5432 (2025) Cite this article The electrical performance of high energy storage density materials has always been a research direction that has received high attention.
Element doping is the simplest way to increase the energy storage density of inorganic materials. It is greatly effective to increase the relaxation and reduce the remanent polarization by doping (La, Sm, Zr, etc.), which is beneficial for the energy storage density and efficiency [83, 84, 85].
Revealed the excellent performance of high energy storage density materials: The study found that GO performs best in energy storage efficiency, 30% higher than the traditional material AEC; in terms of electrical response time, the average response time of GO is only 0.35 s, 85% faster than AEC.
Therefore, simplifying the structure and lowering the cost are considerable for enhancing the energy storage performance commercially. In recent years, the in-depth research on energy storage materials is expected to further realize the wider applications of dielectric capacitors.
Next, the methods of improving the energy storage density of dielectric capacitors are concluded. For ceramic blocks and films, methods, such as element doping, multi-phase solid solution/coexistence structure, “core–shell” structure/laminated structure, and other interface adjustments, are effective to increase the energy storage density.
