摘 要：Inorganic solid-state electrolytes(SSEs)are nonflammable alternatives to the commercial liquid-phase *** enables the use of lithium(Li)metal as an anode,providing high-energy density and improved stability by avoiding unwanted liquid-phase chemical *** the different types of SSEs,the garnet-type electrolytes witness a rapid development and are considered as one of the top candidates to pair with Li metal due to their high ionic conductivity,thermal,and electrochemical ***,the large resistances at the interface between garnet-type electrolytes and cathode/anode are the major bottlenecks for delivering desirable electrochemical performances of all-solid-state batteries(SSBs).The electrolyte/anode interface also suffers from metallic dendrite formation,leading to rapid performance *** is a fundamental material challenge due to the poor contact and wettability between garnet-type electrolytes with electrode ***,we summarize and analyze the recent contributions in mitigating such materials challenges at the *** used to address these challenges are divided into different categories with regard to their working *** one hand,progress has been made in the anode/garnet interface,such as the successful application of Li-alloy anode and different artificial interlayers,significantly improving interfacial *** the other hand,the desired cathode/garnet interface is still hard to reach due to the complex chemical and physical structure at the *** common methods used are nanostructured cathode host and sintering additives for increasing the contact *** the basis of this information,we present our views on the remaining challenges and future research of electrode/garnet *** review not only motivates the need for further understanding of the fundamentals,stability,and modifications of the garnet/electrode interfaces but also provides guidelines for the future de
