Here, we propose an alternative approach through a rational design of lead-free ferroelectric/paraelectric (BiFeO<sub>3</sub>/SrTiO<sub>3</sub>) multilayers. Utilizing the phase-field model, we demonstrate that the energy storage density and charge–discharge efficiency can be optimized by adjusting the volume fractions of BiFeO<sub>3</sub>. A volume fraction of 0.69 BiFeO<sub>3</sub> yields the highest discharge energy storage density (58.01 J/cm<sup>3</sup>) and near-perfect charge-discharge efficiency (99.8%) at 4 MV/cm. The multilayers exhibit varying hysteresis behaviors, from ferroelectric to relaxor to paraelectric-like characteristics, depending on the BiFeO<sub>3</sub> ratio. This study reveals that different polarization domain structures correspond to these behaviors, transitioning from stripe to spiral to in-plane patterns as the ferroelectric volume is reduced. Notably, the polarization spiral structure maintains excellent energy storage across temperatures up to 550<!--> <sup>∘</sup>C.
