In this context, the present study aims to synthesize and evaluate the structural, microstructural, and relaxation properties of nanocrystalline Li₂NiZrO₄ for potential solid-state electroceramic applications. Lithium-rich Li₂NiZrO₄ was prepared via a glycine-assisted solution combustion route using a stoichiometric (1:1) oxidizer–fuel ratio, enabling the formation of a phase-pure nanocrystalline compound. Structural analysis using X-ray diffraction confirmed a single-phase cubic lattice with an average crystallite size of ~ 51 nm, while TG–DTA verified its thermal stability. SEM imaging revealed a uniform surface morphology, and EDS confirmed the expected elemental composition. TEM and HRTEM further validated the nanocrystalline nature, showing monodisperse domains with an average size of 47.9 ± 0.02 nm. Impedance spectroscopy was employed to probe relaxation dynamics over a wide temperature range. The frequency-dependent electric modulus, M″(ω), exhibited well-defined relaxation peaks, and the corresponding relaxation time (τ = 1/ωₚ) followed Arrhenius behaviour with an activation energy of 0.39 ± 0.02 eV, indicating facile Li⁺ ion migration or dipolar reorientation. The temperature-invariant scaling of modulus spectra suggests a common relaxation mechanism governing charge transport. Overall, the study demonstrates that nanocrystalline Li₂NiZrO₄ possesses favourable structural stability, nanoscale coherence, and low activation energy for ionic motion.
