Abstract
All solid-state batteries (ASSBs) enlighten the development of next secondary batteries with high energy density and safety, but still suffer from the obstacles of mechanical failure and sluggish ionic transportation. Herein, we present a quench induced local disordered Li2.7Zr0.3In0.7Cl6 (LZIC) halide solid electrolyte, which shows prominent compressibility and ionic conductivity. Mechanically, quench ‘freeze’ the high temperature state of LZIC, transforming LZIC from conventional high rigid crystalline state to softer local disordered glass-ceramics, thus significantly curtails the Young’s modulus from 53.5 GPa to 11.8 GPa. Ionic conductively, local disordering not only reduces the grain boundary resistance as the improved ionic conduction consecutiveness, but also promotes the bulk ionic transportation kinetics as the increased defects and enlarged lattice volume, which synergistically increased the ionic conductivity of LZIC from 1.07 mS/cm to 4.25 mS/cm. The co-promoted compressibility and ionic transportation of LZIC enabled a stable cycling of ASSBs at an ultra-low stack pressure of 3 MPa, thus providing new theoretical and technical approaches for the industrialization of ASSBs.
