  • Lead Zirconate-Based Antiferroelectric Ceramics with Improved Energy Efficiency and Method of Making Same
    Publication number: 20250174401
    Abstract: Disclosed are embodiments of an antiferroelectric (AFE) ceramic. The AFE ceramic includes a PbZrO3-based composition. The AFE ceramic has a charge-discharge energy efficiency of at least 96%, and the AFE ceramic has a recoverable energy density of at least 2.8 J/cm3 at a peak field of at least 200 kV/cm. Embodiments of a method of identifying potential AFE ceramic compositions having high energy efficiency and recoverable energy density are also disclosed.
