Abstract
- Dielectric capacitors offer great potential for advanced electronics due to their high power densities, but their energy density still needs to be further improved. High-entropy strategy has emerged as an effective method for improving energy storage performance, however, discovering new high-entropy systems within a high-dimensional composition space is a daunting challenge for traditional trial-and-error experiments. Here, based on phase-field simulations and limited experimental data, we propose a generative learning approach to accelerate the discovery of high-entropy dielectrics in a practically infinite exploration space of over 10<superscript>11</superscript> combinations. By encoding-decoding latent space regularities to facilitate data sampling and forward inference, we employ inverse design to screen out the most promising combinations via a ranking strategy. Through only 5 sets of targeted experiments, we successfully obtain a Bi(Mg<subscript>0.5</subscript>Ti<subscript>0.5</subscript>)O<subscript>3</subscript>-based high-entropy dielectric film with a significantly improved energy density of 156 J cm<superscript>−3</superscript> at an electric field of 5104 kV cm<superscript>−1</superscript>, surpassing the pristine film by more than eight-fold. This work introduces an effective and innovative avenue for designing high-entropy dielectrics with drastically reduced experimental cycles, which could be also extended to expedite the design of other multicomponent material systems with desired properties. High-entropy ceramic dielectrics show promise for capacitive energy storage but struggle due to vast composition possibilities. Here, the authors propose a generative learning approach for finding high-energy-density high-entropy dielectrics in a practically infinite exploration space of over 10<superscript>11</superscript> combinations.
