All‐solid‐state lithium batteries (ASSLBs) are considered to be the next‐generation energy storage system, because of their overwhelming advantages in energy density and safety compared to conventional lithium ion batteries. Among various systems, garnet‐based ASSLBs are one of the most promising candidates. The advantages arise from the intrinsic properties of garnet electrolytes, especially the high shear modulus and wider electrochemical window compared to that of polymer and sulfide electrolytes, guaranteeing the application of Li metal and high voltage cathodes. However, the interfacial issues between garnets and electrodes (Li metal and cathodes) are challenging and hinder the further development of garnet‐based ASSLBs. Herein, the origin of interfacial resistance and recent development of interfacial construction in garnet‐based ASSLBs are reviewed, as well as the subsequent interfacial degradation and cell failure during cycling process, including inhomogeneous plating and stripping, Li dendrites, and strain induced microcracks in stiff electrodes. Finally, the future challenges and opportunities in this important and exciting field are also presented.

基于石榴石的全固态锂电池中的接口

全固态锂电池（ASSLB）被认为是下一代储能系统，因为与常规锂离子电池相比，它们在能量密度和安全性方面具有压倒性的优势。在各种系统中，基于石榴石的ASSLB是最有前途的候选者之一。石榴石电解质的固有特性，特别是与聚合物和硫化物电解质相比，具有较高的剪切模量和更宽的电化学窗口，从而具有优势，从而保证了锂金属和高压阴极的应用。但是，石榴石和电极（锂金属和阴极）之间的界面问题具有挑战性，并阻碍了基于石榴石的ASSLB的进一步发展。在这里 回顾了基于石榴石的ASSLB中的界面抗性的起源和界面结构的最新发展，以及循环过程中随后的界面降解和细胞衰竭，包括不均匀的电镀和剥离，锂枝晶以及在刚性电极中应变诱发的微裂纹。最后，还介绍了这个重要而令人兴奋的领域中的未来挑战和机遇。
