Solid-state lithium batteries (SSLBs) utilize solid electrolytes (SEs) instead of their liquid counterpart, providing higher energy density and safety, are considered as potential storage technology. Among the various kinds SEs, garnet (Li7La3Zr2O12, LLZO) electrolyte has considerable Li-ion conductivity robust air/chemical stability, rendering it an excellent candidate for commercialization SSLBs. In recent years, numerous efforts have been made to improve ionic SEs. These successfully achieved a high ∼10–3 S cm–1 at room temperature. Nevertheless, emerging issue pertains interfacial stability garnet-based electrolytes. Therefore, our focus lies on challenges associated with SSLBs, including (i) interface between metal anode SE, (ii) SE high-voltage cathodes, (iii) polymeric additives SE. The solution strategies these target-oriented issues briefly discussed. light discourse enhanced performance, principle designing high-performance interfaces is proposed. A future perspective also offered development
