Abstract

This paper explores the use of entropy engineering to create high-entropy superparaelectrics (SPEs) for enhanced energy storage. By disrupting long-range ferroic orders, the researchers achieved locally diverse ferroic distortions, leading to improved polarization response, negligible remnant polarization, delayed polarization saturation, and enhanced breakdown electric fields. A high recoverable energy density of 15.48 J cm⁻³ and an ultrahigh energy storage efficiency of 90.02% were achieved, surpassing previous bulk superparaelectric materials.
