Abstract：Due to the huge potential of application, the advanced polymer-based insulating materials with high energy storage density have developed fast in the recent years. This paper briefly introduced the importance of these materials, and explained the mechanism of energy storage for dielectrics. The connections between energy density and the properties of these materials were also introduced, such as dielectric permittivity, electric displacement and breakdown strength. The ways to calculate energy density and charge-discharge efficiency were discussed too. Then the recent research developments of dielectric polymers and the dielectric nanocomposites were summarized respectively, focusing on the strategies of fabrication, processing procedure, the microcosmic and macroscopic mechanism analyses and the characterization of materials. Finally, the progress and future perspectives of the polymer-based insulating materials with high energy density were summarized.
