“…Lithium-based batteries, such as lithium-ion and lithium–metal batteries (LMB), have become indispensable power sources for various applications ranging from portable electronic devices to electric vehicles and grid energy storage systems. − The performance and safety of these batteries are strongly influenced by the solid electrolyte interphase (SEI), a thin and complex film that forms on the electrode surface during battery operation. − The SEI acts as a vital interface between the electrode and the electrolyte, facilitating the transport of lithium ions and preventing undesirable side reactions. , …”

The solid-electrolyte interphase (SEI) in lithium-based batteries has been extensively studied regarding its composition, structure, and formation mechanisms. However, an understanding of the ion transport through the SEI remains incomplete. Revealing the underlying ion diffusion processes across the SEI holds great potential for enhancing battery performance and improving safety. In this study, we present the outcomes of first-principles density functional theory (DFT) calculations based on cryogenic high-resolution transmission electron microscopy (cryo-HRTEM) imaging, which elucidate the dominant diffusion pathways, energetics, and diffusion coefficients associated with lithium (Li) diffusion through the polycrystalline SEI. Specifically, we focus on Li diffusion through the grain boundaries (GBs) formed by the three primary inorganic components of the SEI, namely, Li 2 O, LiF, and Li 2 CO 3 . Our findings reveal that Li diffusion primarily occurs through numerous open channels created by the GBs. The energetics and potential barriers reveal significant variations depending upon the structural characteristics of these channels, with a distinguished trend being faster Li diffusion within the GB compared to neighboring crystalline regions within the grain interiors. The analysis of the charge density in GBs revealed that Li dendrite formation occurs in GBs with less Li diffusion kinetics.

Next‐generation batteries have long been considered a transition to more sustainable storage technologies. Among them, metal–air batteries (MABs) with low cost, high safety, and environmental friendliness have shown great potential for future large‐scale applications. Motivated by the desirable characteristics, significant progress is made in suppressing serious parasitic reactions, improving electrochemical performance, and increasing the energy density in MABs. Compared to the widely reported liquid electrolyte strategy, solid‐state electrolytes (SSEs) can thoroughly solve the volatilization challenges of liquid electrolytes and protect the oxygen electrodes without the formation of diffusion‐blocking oxide phases. Notably, SSEs for MABs are still in their infancy, and many thorny challenges still need to be solved. In this review, the main electrochemical mechanism, key challenges, and some important progress are sorted out for solid‐state MABs, such as lithium–air, zinc–air, aluminum–air, and magnesium–air batteries. Besides their fundamental significance, these configurations are further compared in terms of energy density, cost, carbon footprint, energy consumption, rate performance, cycle performance, safety, and air stability of prevailing electrolytes.
