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] ].

To quantitatively evaluate the trade-off between high polarization (large Ue) and low hysteresis (low Uloss and thus high η) for high overall energy storage performance, we defined a parameter UF = Ue / (1 − η). From the simulated P - E loops of Sm-BFBT (fig. S4), we derived the Ue and η values and calculated UF.
