Polyimide (PI) has attracted wide attention in the field of new high-temperature energy storage dielectric materials because of its excellent properties. Compared with inorganic/PI composite dielectric materials, all-organic PI composite dielectric materials can maintain excellent mechanical properties while obtaining high dielectric permittivity and high energy storage density. This paper firstly discussed the key parameters affecting the energy storage characteristics of polymer dielectric materials, including dielectric permittivity, dielectric loss, breakdown field strength, energy storage density, charge/discharge efficiency, and heat resistance. And then introduced the key factors and development trends affecting the energy storage characteristics of all-organic PI composite dielectric materials from physical blending and chemical blending, respectively. Finally, the problem of how to effectively improve the high-temperature energy storage characteristics of all-organic PI composite dielectric materials was summarized and the future development direction was proposed.
