Summary: Li metal anode is considered as the ultimate anode material for rechargeable batteries due to its high theoretical specific capacity and low negative electrochemical potential. However, the uncontrolled Li dendrites and side reactions with electrolytes hinder its commercialization. This review summarizes the strategies for artificial solid electrolyte interphase (SEI) engineering in liquid and solid electrolytes. The ideal artificial SEI should consider the component, distribution, and structure. This review provides perspectives for SEI design and lays a foundation for future research and development of Li metal batteries.

Summary: A precast solid electrolyte interface (SEI) film based on a PVDF-HFP matrix is studied, where the addition of LiBOB, SiC, and PEO improves the cycle stability of the substrate and extends the lifespan of the Li metal anode.

Summary: This study investigates the synergistic effect of functional alloying structure and Li+ solvation mediated interfacial kinetic on lithium metal protection. By constructing a Li alloy matrix with a bi-functional silver-Li3N blended interface, fast Li+ conductivity and high Li affinity can be achieved, leading to decreased nucleation and mass transfer-controlled overpotentials. Additionally, the inward diffusion depth of Li adatoms inside Ag sites can be limited by the Li+ solvation structure, thus elongating the Li protection ability of the Ag-Li3N interface.

Summary: A key challenge in lithium-ion batteries is the instability of electrolytes against anode materials, with the solid-electrolyte interphase (SEI) providing stability at the cost of capacity consumption. Artificial SEIs offer more flexibility to tune properties such as chemical composition and impedance, but must ensure sufficient transport properties for Li-ions and stability.

Summary: Poly(ethylene oxide) (PEO) based solid-state electrolytes show potential for practical all solid-state Li-metal batteries (ASSLMBs) due to their good chemical stability. However, the use of thin PEO presents a risk of short circuit in its semi-molten state, and PEO can be oxidatively decomposed by cathodes under high voltage, hindering the practical application of PEO-based ASSLMBs. In this study, the introduction of Nanodiamonds (NDs) into PEO electrolytes is found to greatly improve the electrochemical performance of PEO-based batteries by readjusting the Li+ and e(-) conductivity at the anode/cathode interface.

Summary: A low-concentrated and nonpolar n-hexane-diluted electrolyte (LCDE) is proposed to alleviate the issues of uneven lithium deposition and the shuttle of lithium polysulfides (LiPSs) in lithium-sulfur batteries. The nonpolar effect of n-hexane promotes the homogeneous deposition of lithium and reduces the solubilities of LiPSs, eliminating the shuttle effect. Moreover, the ultra-light n-hexane diluent reduces the density and weight of the electrolyte, resulting in a high energy density in the Li-S pouch cell.
