Abstract

Stabilizing cubic polymorph of Li₇La₃Zr₂O₁₂ at low temperatures is challenging and currently limited to mono- or dual-ion doping with aliovalent ions. Herein, a high-entropy strategy at the Zr sites was deployed to stabilize the cubic phase and lower the lithium diffusion activation energy, evident from the static ⁷Li and MAS ⁶Li NMR spectra.
