The essence of the scientific problem in all solid-state batteries lies in the properties of the introduced solid electrolyte and the existence of a new solid-solid interface. Starting from the structure-property relationship, the structural evolution of the solid-solid interface and the electrolyte itself, and the matter transport process determine the performance of the all-solid-state battery. With the continuous enrichment of solid electrolyte materials, the current problems in all solid-state batteries are mainly concentrated on the solid-solid interface. The composition and structure at the interface limit the performance of all solid-state batteries. According to the different situations of solid-solid interface contact, this article summarizes and discusses the structure and matter transport at the solid-solid interface in all solid-state batteries according to the three levels of solid-solid interface physical contact, chemical contact and surface modification. Finally, the relationship between local symmetry and material properties under the macroscopic complex system is discussed from the perspective of the functional origin of functional materials.
