Capacitors exhibit exceptional power density, a vast operational temperature range, remarkable reliability, lightweight construction, and high efficiency, making them extensively utilized in the realm of energy storage. There exist two primary categories of energy storage capacitors: dielectric capacitors and supercapacitors.
The energy storage density of the metadielectric film capacitors can achieve to 85 joules per cubic centimeter with energy efficiency exceeding 81% in the temperature range from 25 °C to 400 °C.
However, electrostatic capacitors lag behind in energy storage density (ESD) compared with electrochemical models 1, 20. To close this gap, dielectrics could amplify their energy storage per unit planar area if packed into scaled three-dimensional (3D) structures 2, 5.
Electrostatic capacitors can enable ultrafast energy storage and release, but advances in energy density and efficiency need to be made. Here, by doping equimolar Zr, Hf and Sn into Bi4Ti3O12 thin films, a high-entropy stabilized Bi2Ti2O7 pyrochlore phase forms with an energy density of 182 J cm−3 and 78% efficiency.
Dielectric electrostatic capacitors have emerged as ultrafast charge–discharge sources that have ultrahigh power densities relative to their electrochemical counterparts 1. However, electrostatic capacitors lag behind in energy storage density (ESD) compared with electrochemical models 1, 20.
The integration of high thermal conductivity and low dielectric loss is a benefit for high-temperature energy storage capacitors. The MDs are an emerging new composite material designed and manufactured artificially with unexpected properties 30, 31. Till now, however, MDs for high-temperature energy storage applications are still unexplored.
