摘要

We observe the influence of Al occupancies in Li sites on the formation process of the garnet solid electrolyte of Li_7La_3Zr_2O_(12)(LLZO).A direct incorporation of Al is first promoted in a Li-insufficient garnet solid electrolyte during the calcination process of 850°C and then the cubic phase of LLZO is obtained after successive annealing step of 1000°C.Comparing to pristine LLZO,Al incorporated LLZO shows less formation of Li_2CO_3,keeping crystallographic and physicochemical properties.This Al incorporation improves both the ionic conductivity and interfacial resistance to poisoning procedure.
