(1 − x)(K0.45Na0.45Li0.04La0.02)NbO3–xSr(Ni1/3Nb2/3)O3 [(1 − x)KNLLN–xSNN, 0.005 ≤ x ≤ 0.02] ceramics were synthesized by a conventional solid-state reaction method. The influences of Sr(Ni1/3Nb2/3)O3 doping on the phase structure, microstructure and dielectric property of KNLLN-based ceramics were investigated. The results showed that the 0.995KNLLN–0.005SNN ceramic has high εr ~ 1461 and good thermal stability (Δε/ε127°C≤ ± 13%) in the temperature range of 127–470 °C. And the calculation of the relaxation activation energy indicates that the thermal activation may be mainly caused by the double ion oxygen vacancies.
