Effect of Ca Doping on Structure and Electrochemical Properties of Li3/8Sr7/16Hf1/4Nb3/4O3 Lithium‐Ion Conductors

Batteries &Supercaps, Volume 9, Issue 4, April 2026.
Perovskite‐structured solid electrolytes are promising candidates for next‐generation solid‐state lithium batteries due to their high ionic conductivity and structural stability. In this work, Li3/8Sr7/16−xCaxHf1/4Nb3/4O3 solid electrolytes with various calcium contents (x = 0, 0.02, 0.05, 0.08, and 0.44) were synthesized via a sol–gel method, followed
