Abstract Li 2 ZrCl 6 (LZC) solid electrolyte has been recognized as a promising candidate for all‐solid‐state batteries (ASSBs), owing to its remarkable compatibility with high‐voltage cathodes and the cost advantage among halide electrolytes. However, ionic conductivity of LZC (≈0.4 mS cm −1 ) requires enhancement. Herein, rare earth metal elements (La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Yb, Y) have doped into LZC, resulting in doubling conductivity. Moreover, Ta 5+ is utilized further modulate concentration + enhance reduce dosage expensive rare‐earth metal. Using Li‐Zr‐Dy‐Cl component case study, 16 types Dy 3+ co‐doped electrolytes synthesized optimal 2.1 Zr 0.8 0.15 0.05 Cl (LZDTC) exhibits 1.67 . Three‐dimensional Li‐ion transport pathways LZDTC revealed. The dual‐substitution at site changes length Li‐Cl bond occupation, thereby reducing resistance migration. ASSBs Li‐In/LGPS‐LZDTC/NCM811 demonstrate capacity 117 mA h g after 500 cycle 0.5 C 74% retention rate, highlighting effectiveness dual‐doping strategy creating superionic conductors ASSBs.

Although aliovalent ion substitution is an important strategy for enhancing ionic conductivity in halide electrolytes, the choice of doping ions often restricted to tetravalent ions, and investigations into intrinsic origin mechanism are lacking. In this work, we investigated effects Zr4+, Ta5+ W6+ on crystal structure yttrium-based rare-earth halides. Only Zr4+ achieves fast diffusion both (001) (002) planes by affecting volume octahedron tetrahedral interstitial space, whereas significantly enhances rate plane while suppressing it plane, does opposite. As a result, optimal (0.437 mS cm-1) obtained substitution, corresponding full battery also exhibits excellent capacity, cycling performance.
