Li7La3Zr2O12固态电解质负极界面研究进展
Progress of Li7La3Zr2O12 Solid Electrolyte Anode Interface
摘要
Abstract
The garnet-type solid electrolyte Li7La3Zr2O12(LLZO)has a wide electrochemical window of 5 V,and among current solid electrolyte systems,it has a good match with the metal lithium anode,which makes it promising to develop into the next-generation high-energy battery.However,the problem of contact stability between LLZO and the electrode greatly limits its practical application.In this paper,we first analyze the stability of the LLZO/Li anode interface from three aspects:the properties of lithium metal anode,the properties of LLZO solid electrolyte,the interfacial contact of LLZO and lithium metal anode.Then we also expound the root cause of interface stability,summarize the corresponding optimization method.Finally,we put forward the problems that should be paid attention to the development of the LLZO/Li anode interface as a reference to the practical application of all-solid-state lithium-ion batteries.关键词
