Summary: This study demonstrates the importance of building robust solid electrolyte interphase (SEI) in stabilizing microsized alloy anodes, by regulating the electrolyte chemistry to enhance the elasticity of SEI. The SEI constructed in ether-based electrolyte effectively encapsulates microsized Sb anodes, preventing capacity loss and achieving sustained high capacity in K-ion batteries through an intercalation-assisted alloying reaction mechanism.

Summary: The growth of dendrites during electrodeposition still significantly hinders the practical application of lithium metal batteries. Lithium nitride modification is an effective strategy to suppress the growth of lithium dendrites. This review summarizes recent strategies of using lithium nitride to construct solid electrolyte interlayers to inhibit dendrite growth, including applying Li3N-based SEIs or ASEIs, constructing a nitrogenous microscopic structure, liquid electrolyte modification, and solid electrolyte modification. Efforts are made to provide a roadmap for constructing more stable SEIs and fabricating better batteries.

Summary: By rational topological design, a topological polymer-reinforced interphase layer is in situ constructed using a synthesized solid polymer electrolyte, which addresses the incompatible interphases resulting from the contradiction between impedance and mechanical strength. The constructed topological solid electrolyte interphase (SEI) layer harmonizes mechanochemical stability and fast diffusion dynamics of Li+, ensuring the integrity and stability of the SEI layer. Additionally, the formation of the topological interphase layer enables highly stable and reversible Li nucleation/stripping behaviors exceeding 3000 h and superior cycling performance of practical LiFePO4/Li metal battery beyond 500 cycles.

Summary: This study investigates the structures, thicknesses, and Young's moduli of three types of solid-electrolyte interphases (SEIs) in Li metal batteries using in-situ atomic force microscope (AFM) based nanoindentation and peak force quantitative nanomechanics (QNM) methods. The study finds that SEIs formed by electrochemical reduction have a traditional double layer structure and are thicker with smaller Young's moduli compared to the inorganic-organic hybrid SEIs formed with chemical reactions.

Summary: This study introduces a methodology for observing the relationship between the morphology of lithium metal anodes and the chemistry of the solid electrolyte interphase. The coexistence of LiF and Li3N in the SEI layer is found to prevent dendrite formation during lithium deposition, allowing for the visualization of individual lithium deposits with different microstructures. These findings have potential implications for future energy storage devices.

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.
