Abstract Graphite anodes are prone to dangerous Li plating during fast charging, but the difficulty identify rate‐limiting step has made a challenging eliminate thoroughly. Thus, inherent thinking on inhibiting needs be compromised.

High safety and stable wide-temperature operation are essential for lithium metal batteries (LMBs). Herein, we designed an amide-based eutectic electrolyte composed of N-methyl-2,2,2-trifluoroacetamide (NMTFA) difluoro(oxalato)borate, enabling LMBs’ wide-operating temperature range fast-charging performance. In addition to high thermal tolerance non-flammability, our (AEEs-5) triggers a temperature-dependent Li solvation structure due the motion polar NMTFA, ensuring appropriate Li-ion...
A stable solid electrolyte interphase (SEI) layer is crucial for lithium metal anode (LMA) to survive in long-term cycling. However, chaotic structures and chemical inhomogeneity of natural SEI make LMA suffering from exasperating dendrite growth severe electrode pulverization, which hinder the practical application LMAs. Here, we design a catalyst-derived artificial with an ordered polyamide-lithium hydroxide (PA-LiOH) bi-phase structure modulate ion transport enable dendrite-free Li...

Abstract The lithium (Li) dendrite growth seriously hinders the applications of metal batteries (LMBs). Numerous methods have been proposed to restrict formation Li dendrites by improving Li‐ion transference number (t + ) through separator modification according Sand's time equation. However, ignoring positive contribution anion motion solid electrolyte interphase (SEI) will result in insufficient inorganic components, which impedes practical implementation LMBs. Herein, a “tandem” is...
Constructing an artificial solid electrolyte interphase (ASEI) on Li metal anodes (LMAs) is a potential strategy for addressing the dendrite issues. However, mechanical fatigue of ASEI caused by stress accumulation under repeated deformation from plating/stripping not taken seriously. Herein, this work introduces mechanically interlocked [an]daisy chain network (
Lithium metal anodes (LMAs) are critical for high-energy-density batteries such as Li-S and Li-O2 batteries. The spontaneously formed solid electrolyte interface on LMAs is fragile, which may not accommodate the cyclic Li plating/stripping. This usually will result in a low coulombic efficiency (CE), short cycle life, potential safety hazards induced by uncontrollable growth of lithium dendrites. In this study, we fabricate alginate-based artificial SEI (ASEI) layer that chemically stable...
Coupling of triporosity and strong Au–Li interaction leads to dendrite-free long-life LMAs.
