Optimization of energy storage density in ceramic capacitors

open access: yesJournal of Physics D: Applied Physics, 1996
A theoretical treatment, based on the Devonshire theory of ferroelectrics, is presented to describe the storage of electrostatic energy in ferroelectric and paraelectric materials at very high field strengths. In all cases, optimal energy density is achieved by using compositions with Curie temperatures well below the operating temperature.
