dc.description.abstractLead-free (Sr<inf>0.3</inf>Bi<inf>0.35</inf>Na<inf>0.335</inf>Li<inf>0.015</inf>) (Ti<inf>1−x</inf>Zr<inf>x</inf>) O<inf>3</inf> ceramics (SBNLT<inf>1−x</inf>Zr<inf>x</inf>) with x = 0–0.04 were prepared via the solid-state combustion technique using glycine as the fuel. The influence of Zr content on the phase structure, microstructure, electrical properties, and energy storage properties of the SBNLT<inf>1−x</inf>Zr<inf>x</inf> ceramics was examined. The presence of a pure perovskite phase was shown by X-ray diffraction (XRD) patterns, with the coexistence of rhombohedral and tetragonal phases in all samples, as certified by the Rietveld refinement method. Scanning electron microscopy (SEM) was utilized to observe the morphology of the SBNLT<inf>1−x</inf>Zr<inf>x</inf> ceramics, which revealed cube shaped grains with anisotropic growth. Average grain size increased from 2.01 to 2.49 µm when x increased from 0 to 0.01 and then reduced with further increases in Zr content. The maximum dielectric constant dropped from 4667 to 2990 when x increased from 0 to 0.04, caused by a shift from the morphotropic phase boundary (MPB). The maximum polarization (P<inf>max</inf>) of 29.18 µC/cm<sup>2</sup>, energy storage density (W<inf>total</inf>) of 0.851 J/cm<sup>3</sup> and recoverable energy storage (W<inf>rec</inf>) of 0.609 J/cm<sup>3</sup> were achieved when x = 0.02.
