摘要
Abstract
Lithium Lanthanum Zirconium Oxide(LLZO)has attracted attention as a solid-state electrolyte material due to its high ionic conductivity,but the traditional solid-phase method requires high temperature for preparation,resulting in high energy consumption.This study proposes an Al2O3 assisted sintering process,which reduces the densification temperature of LLZO to 1050℃by optimizing the raw material ratios and sintering parameters of Li2CO3,La2O3,and ZrO2.Experiments have shown that when 1.5 wt%Al2O3 is added,the ion conductivity of the sample reaches 1.2×10-3S/cm,and the relative density increases to 96.5%.The pilot production verification shows that this process reduces energy consumption by 18%for a single batch(50kg)and increases the yield from 78%to 92%.The results indicate that the Al2O3 assisted solid-phase method significantly reduces the industrialization threshold while ensuring performance,providing a feasible solution for the large-scale preparation of solid electrolytes.关键词
