Stable solid electrolytes are essential for advancing the safety and energy density of lithium batteries, especially in high-voltage applications. In this study, we designed an innovative high-entropy chloride electrolyte (HE-5, Li2.2In0.2Sc0.2Zr0.2Hf0.2Ta0.2Cl6), using multielement doping to optimize both ionic conductivity stability. The disordered lattice structure facilitates lithium-ion mobility, achieving 4.69 mS cm–1 at 30 °C activation 0.300 eV. Integration HE-5 into all-solid-state batteries (ASSBs) with NCM83 cathodes a Li–In anode enables outstanding electrochemical performance, sustaining 70% capacity retention over 1600 cycles 4 C rate. Moreover, high configurational entropy stabilizes electrolyte's elevated voltages, enabling stable operation 5.0 V without significant degradation. Our work presents dual advantages engineering boosting voltage stability, providing broad roadmap next-generation energy-dense ASSBs.
