Boosting lithium-ion transport in halide solid-state electrolytes by aliovalent substitution for all-solid-state lithium-ion batteries
We report a novel chemical aliovalent substitution strategy that induces lithium vacancy generation, expands 3D Li<sup>+</sup> migration channels, and reduces activation energy. The optimized composition Li<sub>1.8</sub>Zr<sub>0.8</sub>Nb<sub>0.2</sub>Cl<sub>6</sub> achieves a room-temperature ionic conductivity twice higher than that of pristine Li<sub>2</sub>ZrCl<sub>6</sub>, realizing stable cycling in all-solid-state lithium-ion batteries.
