 Antiferoelectric materials are promising candidates for high energy density capacitor applications due to their unique properties such as low dielectric loss, low course of field, low remnant polarization, high energy density, high material efficiency, and fast discharge rates. Despite the potential benefits, there has been limited research done in this area. This paper provides a comprehensive review of the current state of knowledge in the field, including physical and chemical routes for enhancing energy storage density.
