“…However, the insufficient mechanical properties of these in‐situ SEI films fail in extending the long‐term cycling life of Li metal anodes, which suffer from high volume fluctuation and serious Li dendrite formation. In comparison, the ex‐situ coating of artificial SEI films, including inorganic ceramics, [ 22–24 ] organic polymers, [ 25–27 ] and their hybrids, [ 28–30 ] on the Li metal surface have attracted much attention for realizing dendrite‐free Li metal anodes, due to the facilely tunable structural properties of these artificial SEI films. In this regard, inorganic ceramic layers are equipped with high mechanical rigidity and good ionic conductivity to inhibit Li dendrite growth, but their frangibility usually results in cracks during Li plating/stripping processes.…”

A robust artificial solid electrolyte interphase (SEI) film with biomimetic ionic channels and high stability is rationally designed and fabricated by combining the ClO4−‐decorated metal‐organic framework (UiO‐66‐ClO4) and flexible lithiated Nafion binder (Li‐Nafion). The high electronegativity and lithiophilicity of ClO4− groups chemically anchored into the UiO‐66 channels endow the SEI film with an excellent single‐ion conducting pathway, high Li+ transference number, and outstanding ionic conductivity, which can effectively prohibit undesirable reactions of the Li metal with the electrolyte and regulate fast and uniform Li+ flux. With further assistance of the flexible Li‐Nafion binder, the resulting UiO‐66‐ClO4/Li‐Nafion (UCLN) composite film exhibits an excellent mechanical strength to suppress the growth of Li dendrites and maintain the integral stability of the Li metal anodes during cycling. Consequently, the UCLN coated Li metal anodes (Li@UCLN) deliver remarkable cycling stabilities even under a high current density of up to 20 mA cm−2 and large areal capacity of up to 30 mAh cm−2, as well as enhanced rate capacities and cycle lifespans in the full cells even under the harsh conditions for high‐energy density applications.

“…Lithium alloy anodes for rechargeable ambient temperature lithium batteries have been studied since the early 1970 39,40 . During the past 40 years, a great deal of literature have been reported using lithium‐containing alloys as the anode materials for lithium ion batteries 18,29,31‐33,37,41‐43 . From the reported literatures, we can conclude that there are several kinds of methods to synthesize these lithium alloys, including; fusion reaction, electrochemical lithiation/deposition, magnetron sputtering, and ball‐milling, as shown in Table 1.…”

“…Li 3 Sb and Li 3 Bi alloy anodes have also been investigated in metal lithium batteries as early as the 1970s, 68,69 however, there are not too many group VA lithium alloys used directly as anodes in metal lithium batteries. 42,70,94,95 Mainly, that is because of the higher toxicity of some VA elements, such as Sb and As, and the smaller gravimetric capacity of Bi. 33 In addition, the synthesis conditions of VA lithium alloys are highly demanding.…”

Due to the soaring growth of electric vehicles and grid-scale energy storage, high-safety and high-energy density battery storage systems are urgently needed. Lithium metal anodes, which possess the highest theoretical specific capacity (3860 mA h g −1) and the lowest electrochemical potential (−3.04 V vs standard hydrogen electrode) among anode materials, are regarded as the ultimate choice for high-energy density batteries. However, its safety problems as well as the low Coulombic efficiency during the Li plating and stripping process significantly limit the commercialization of lithium metal batteries. Recently, Li-containing alloys have demonstrated vital roles in inhibiting lithium dendrite growth, controlling interfacial reactions and enhancing the Coulombic efficiency (CE) as well as cycle life. Accordingly, in this perspective, the progresses of lithium alloys for robust, stable, and dendrite free anodes for rechargeable lithium metal batteries are summarized. The challenges and future research focus of lithium-containing alloys in lithium metal batteries are also discussed.

Rechargeable batteries have been a profoundly greater part of our lives than we could have ever imagined. The rechargeable Li‐ion batteries (LIBs) that have been developed for transport systems even put fossil fuels in the corner. However, state‐of‐the‐art Li‐ion batteries with graphite anodes are now approaching their theoretical specific energy limits, so they cannot meet the increasing demands of a range of portable electronics and large‐scale energy storage systems. Li metal is one of the most promising anode materials that could break through the energy density bottleneck of Li‐ion batteries due to its ultrahigh specific capacity and very low potential compared to other anode materials. Nonetheless, the direct use of Li metal in commercial battery systems has been hindered due to significant obstacles associated with it such as safety issues, corrosion from chemical reactions that occur inside the battery, or poor cycling performance. The fundamental reason for these problems is the dendritic growth of Li‐ions on the Li metal anode during cycling, as a result of the interfacial phenomena of Li metal and electrolytes. Modification of the Li metal interface with an electrolyte presents an efficient solution to solve these problems. In this review, the current challenges facing the development of Li metal anodes are presented in detail. The most recent advances in Li metal anodes using a controlled interface between the Li metal surface and an electrolyte are highlighted and an introduction on the synthesis and production methods for the application of high‐energy‐density battery systems such as Li‐oxygen (Li−O2), Li‐sulfur (Li−S), and Li metal batteries with high‐energy density cathodes is presented. Furthermore, the recent developments in the in situ/operando analysis tools adopted for the investigation of Li metal anodes such as the structural and chemical changes, dynamic properties, and solid–electrolyte interface (SEI) layer properties are described and summarized. Finally, some suggestions are given in the direction of the development of Li metal with artificial surface layers for use in future high‐energy batteries.
