Lead‐free (1–x)Ba0.9Sr0.1TiO3–xBi(Mg0.5Zr0.5)O3 ((1–x)BST–xBMZ, x = 0–0.15) ceramics are synthesized via citrate combustion process. The grain size is reduced and slimmer hysteresis loops are realized as addition of BMZ. (1–x)BST–xBMZ ceramics exhibit typical relaxor characteristics as x increases. The recoverable energy storage density (Wre = 2.1 J cm−3) and efficiency (η = 88%) are obtained for 0.9BST‐0.1BMZ sample. The energy storage properties of 0.9BST‐0.1BMZ ceramic show excellent frequency stability (Wre varies 4.5% and η varies 1.8% at 5–100 Hz). Moreover, as the temperature increases from 25 °C to 100 °C, the variation of Wre is 7.1% and η keeps unchanged (88%) at 100 kV cm−1.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
