Heterogeneous weakly coupled polar nanoclusters enabling superior high-temperature capacitive energy storage
This paper presents a novel structural design strategy to fabricate BaTiO3-based multilayer ceramic capacitors (MLCCs) with weakly coupled polar nanoclusters in a superparaelectric state. Guided by phase field simulations, the researchers achieved ultrahigh energy storage density of 19.0 J·cm⁻³ and efficiency of 95.5% at room temperature. Crucially, these performance metrics remain superior (>10.0 J·cm⁻³ and >95.0%) over a broad temperature range (25-160 °C), outperforming previously reported ceramic capacitors. The key innovation lies in suppressing nonlinear polarization response and sensitivity through disordered polar configurations, leading to enhanced high-temperature stability. This work offers significant advancements for next-generation electronics requiring high-performance, high-temperature ceramic capacitors.

Scalable Fabrication of High-Performance MLCCs
The advanced repeated rolling processing (RRP) technique used in this study for fabricating SLZ15-RRP ceramic MLCCs offers significant advantages for industrial adoption. This method allows for precise control over microstructure, including grain size refinement and enhanced sintering uniformity, which are critical for achieving high breakdown strength (Eb) and consistent performance. The ability to produce functional multilayer devices with five effective dielectric layers validates the manufacturing readiness of this material system for next-generation electronics. This approach mitigates common challenges in ceramic capacitor fabrication, paving the way for broad commercialization in high-temperature energy storage applications. Our results indicate that the uniform and small grain size, coupled with the weakly coupled polar nanoclusters, directly contribute to the exceptional reliability and stability observed, making this a robust solution for enterprise-level deployment.
