“…The first layer is the solid electrolyte interface (SEI), and the second layer is SEI or PEI. 16,[22][23][24][25]192 Peled et al proposed the mosaic model, which is a recognized description of the SEI structure. It is assumed that the reduction of salt anions and solvents takes place at the same time, and the reduction products (inorganic and organic materials) are deposited on the lithium metal anode surface in the form of embedded microphase.…”

At present, the basic structural mechanisms and improvement methods of solid electrolyte interfaces (SEIs) are still in the research stage. Although many researchers have observed the problems of SEIs by various characterization methods, they still cannot analyze the subtle mechanisms. In this paper, we summarize the formation of SEIs, surface morphology, carrier transport, factors leading to interface challenges, and the progress of research to build better interfaces. Among them, strategies to inhibit the formation and growth of lithium dendrites are one of the focuses of this paper. In addition, another research focus of this paper is to reduce the interfacial resistance by constructing interfacial layers, electrolyte additives, and solid electrolytes. From the current development of battery interface improvement, the inhibition of lithium dendrites and the reduction of interfacial resistance are the most effective methods to improve the interfacial stability. Finally, the article also summarizes the research progress in solving the SEI, analyzes the future research trends for improving the SEI, and gives the research directions.

Despite the potential advantages promised by solid-state batteries, the success of solid-state electrolytes has not yet been fully realised. This is due in part to the lower ionic conductivity of solid electrolytes. In many solid superionic conductors, grain boundaries are found to be ionically resistive and hence contribute to this lower ionic conductivity. Additionally, in spite of the hope that solid electrolytes would inhibit lithium filaments, in most scenarios their growth is still observed, and in some polycrystalline systems this is suggested to occur along grain boundaries. It is apparent that grain boundaries affect the performance of solid-state electrolytes, however a deeper understanding is lacking. In this perspective, the current theories relating to grain boundaries in solid-state electrolytes are explored, as well as addressing some of the challenges which arise when trying to investigate their role. Glasses are presented as a possible solution to reduce the effect of grain boundaries in electrolytes. Future research directions are suggested which will aid in both understanding the role of grain boundaries, and diminishing their contribution in cases where they are detrimental.

Gel‐polymer electrolytes (GPEs) offer a suitable alternative to flammable organic liquid electrolytes in lithium‐oxygen batteries (LOBs) to address safety concerns. However, a major challenge with GPEs is their low ionic conductivity. To enhance the ionic conductivity of GPEs, active inorganic particles have been incorporated. To increase the ionic conductivity of GPE, active inorganic particles have been reinforced in GPE. While this increases the ionic conductivity, it also leads to blockage of the cathode porous structure and reduces the actual surface area of the cathode materials, resulting in poor battery performance. This study proposes a novel double‐layer polymer gel electrolyte (d‐GPE) that exhibits both high ionic conductivity and stability for quasi solid‐state LOBs. The double‐layer GPE consist of a bare GPE layer integrated in the cathode, and a composite GPE (c‐GPE, containing 5wt.% lithium aluminum titanium phosphate (LATP)), which is in contact with Li anode and bare‐GPE. The produced double‐layer gel polymer electrolyte displays high reaction kinetic and better stability due to the excellent electrode/electrolyte interface and rapid oxygen diffusion in the air‐cathode. Furthermore, the d‐GPE electrolyte is resistant to fire and protects Li from dendrite growth and water molecules attack, indicating tremendous promise for the development of practical LOBs.
