不同比例LATP/SPE复合固态电解质与Li金属界面稳定性研究
Study on the interface stability between LATP/SPE composite solid electrolytes with different ratios and lithium metal
摘要
Abstract
In this study,composite solid-state electrolytes(CSEs)were fabricated by incorporating 20%,50%,and 80%of Li1.3Al0.3Ti1.7(PO4)3<LATP>solid electrolyte powder into a poly(ethylene oxide)(PEO)-based solid polymer electrolyte(SPE)matrix via a solution casting method.The microstructural characteristics,ionic conductivity,Young's modulus,and interfacial electrochemical stability with lithium metal anodes of the LATP/SPE composite electrolytes were systematically investigated.Experimental results demonstrated that the CSE containing 50%LATP exhibited optimal electrochemical performance,achieving stable cycling for 1 600 h at a current density of 0.5 mA/cm².This performance significantly surpassed that of composites with 0,20%,and 80%LATP additions.Furthermore,the interfacial failure mechanisms between lithium metal and CSEs with varying LATP contents were thoroughly elucidated.关键词
