However, for ferroelectric energy storage capacitors, a small remanent polarization (P r) is also necessary for obtaining higher discharged energy storage density (W d) and efficiency (η). The classical ferroelectric materials have smaller W d and η values due to their higher P r, which limits their commercialization [ [4], [5], [6] ].
