Optimizing the grain size and grain boundary morphology of (K,Na)NbO3-based ceramics: Paving the way for ultrahigh energy storage capacitors

Relaxor dielectric ceramic capacitors are very attractive for high-power energy storage. However, the low breakdown strength severely restricts improvements to the energy storage density and practical application. Here, a strategy of designing small grain sizes and abundant amorphous grain boundarie...
