In-situ element permeation constructed highly endurable Li-LLZO interface at high current density

Abstract

Building solid/solid SEI is put forward to improve the endurance of LLZO solid electrolyte. Al elements will spontaneously permeate into LLZO and construct a robust Al enriched SEI by the reaction between Al4Li9 and LLZO, reailizing low interfacial impedance of < 1 Ω cm-2, high endurance for 3000 h and high cirticial current density of more than 0.9, 2.3 mA cm-2 at 25oC and 60 oC, respectively.
