Abstract
Energy-storage performances of NaNbO<sub>3</sub> system were effectively enhanced by composition engineering inducing relaxor behavior and grain refinement. Excellent <italic>W</italic><sub>rec</sub> = 3.7 J cm<sup>−3 </sup>and <italic>η</italic> = 82.1% were achieved in the NN-0.04CZ-0.16BNT multilayer capacitors.
