Metallic Li is considered the most promising anode material for high‐energy density batteries due to its high theoretical capacity and low electrochemical potential. However, commercialization of the Li anode has been hampered by the safety issue associated with Li‐dendrite growth resulting from uneven Li‐ion deposition and an unstable solid electrolyte interphase (SEI). Herein, an in situ prepared 10 nm thin film of covalent organic framework (COF) uniformly covered on the Li anode (COF‐Li) is used as an artificial SEI layer for Li plating/striping stabilization and Li dendrite inhibition. Abundant microcellular structures in the COF can redistribute the Li‐ion flux and lead to the homogeneous plating/stripping process. Meanwhile, the superhard mechanical properties and mechanical behavior during needling of the ultrathin COF film is studied via the digital pulsed force mode equipped in atomic force microscopy, illustrating a high Young's modulus of 6.8 GPa that is strong enough to resist dendrite growth. As a result, stable cycling for 400 h is achieved in the COF‐Li symmetrical cell at a current density of 1 mA cm−2, and the internal short circuit is effectively blocked by COF‐Li in Li–S batteries.

“…The approaches include employing 3-dimensional "lithiophilic" current collectors, [4,5] covering Li metal with an artificial uniform SEI, [6][7][8][9] using solid inorganic or polymeric electrolytes [10][11][12] and others, which are comprehensively reviewed in a number of recent works. [3,[13][14][15][16] These routes for suppressing "dendrites" or mossy lithium formation typically rely on the theoretical considerations, which were suggested decades ago, but are still in focus in current reviews. [14][15][16] At the same time recent observations of competing tip and root growth of lithium needles [17][18][19][20][21] and its microstructure revealed by cryo-TEM [22] contradict with many of suggested theoretical models.…”

“…In contrast to graphite, which has nearly constant surface area stabilized by a solid-electrolyte interphase (SEI) upon the first few lithiation cycles, "dendrites" create new surface in each cycle, thus the electrolyte is being continuously consumed for SEI formation on each battery charge. [14][15][16] At the same time recent observations of competing tip and root growth of lithium needles [17][18][19][20][21] and its microstructure revealed by cryo-TEM [22] contradict with many of suggested theoretical models. [3] In addition, non-uniform metal deposition leads to capacity loss due to so-called "dead lithium", which forms when such needle-or bush-like structures dissolve at the base during discharge and loose electrical contact with the electrode.…”

“…Lithium tends to form various needle-like or bush-like structures, often called "dendrites" in literature. [3,[13][14][15][16] These routes for suppressing "dendrites" or mossy lithium formation typically rely on the theoretical considerations, which were suggested decades ago, but are still in focus in current reviews. [2] Needle-like structures can also reach the opposite electrode even causing internal short-circuits and fire.…”

Alexey A. Rulev, [a, b] Artem V. Sergeev, [a, c] Lada V. Yashina, [a] Timo Jacob, [d, e, f] and Daniil M. Itkis* [a] Plating of metallic Li results in deposition of needle-like structures, whose prevention is a fundamental challenge that currently restricts the development and application of high energy Li-metal rechargeable batteries. Over the last decades, a number of mechanisms were proposed to explain morphological instabilities of planar crystallization fronts. The suggested reasons for non-uniform deposition include Li + concentration gradients in the nutrient phase, accelerated electromigration to the tip of the growing needle, specific nucleation behavior, mechanical properties of the solid-electrolyte interphase, and many more. Here, we unravel the role of electromigration currents by adding indifferent cations (TBA + , TEA + ) to screen for non-uniform electric fields, thus, suppressing migrationdriven mass-transfer. Nearly full exclusion of electromigration currents showed no impact on the morphology of electrodeposited lithium. Therefore, the role of electromigration seems negligible, and electric field edge effects are undoubtedly not the main driving force for filament growth during Li plating.Today, lithium-ion batteries are the most wide-spread portable electrochemical energy storage devices. Often referred to as "rocking chair" battery, typical lithium-ion cell operation is enabled by movement of lithium ions from the negative (anode) to the positive electrode (cathode), while the reverse process occurs during charging.

The surface morphology of Li metal anode significantly dictates the stability and safety of Li metal batteries. The key parameters for morphological control and causes for dendritic growth of Li anode are still not clear. Although the plating kinetics is generally believed to be associated with Li growth habits, the detailed models are still not well defined. In this work, the temperature effect on the stability and efficiency of Li anode is systematically investigated in a variety of electrolyte composition for Li metal batteries. A dendrite‐free growth mechanism is observed, and a high Coulombic efficiency up to ≈99.4% in Li||Cu cells is achieved by tuning the deposition behaviors at elevated temperatures. The results provide insights into the Li dendrite growth mechanism and general principle for developing stable Li anode.
