“…[ 38,40 ] Previous methods for controlling lithium metal nucleation such as the use of zero overpotential metallic seeds (Ag and Au) are expensive. [ 19,41 ] Controlling the nucleation of Li on Cu without sacrificing its energy density requires careful chemical synthesis and design, and we posit that surface modification of the Cu current collector by the deposition of a thin nucleation layer may yield a promising low‐cost approach for improved Li metal morphology.…”

The practical implementation of Li metal batteries is hindered by difficulties in controlling the Li metal plating microstructure. While previous atomic layer deposition (ALD) studies have focused on directly coating Li metal with thin films for the passivation of the electrode–electrolyte interface, a different approach is adopted, situating the ALD film beneath Li metal and directly on the copper current collector. A mechanistic explanation for this simple strategy of controlling the Li metal plating microstructure using TiO2 grown on copper foil by ALD is presented. In contrast to previous studies where ALD‐grown layers act as artificial interphases, this TiO2 layer resides at the copper–Li metal interface, acting as a nucleation layer to improve the Li metal plating morphology. Upon lithiation of TiO2, a LixTiO2 complex forms; this alloy provides a lithiophilic surface layer that enables uniform and reversible Li plating. The reversibility of lithium deposition is evident from the champion cell (5 nm TiO2), which displays an average Coulombic efficiency (CE) of 96% after 150 cycles at a moderate current density of 1 mA cm−2. This simple approach provides the first account of the mechanism of ALD‐derived Li nucleation control and suggests new possibilities for future ALD‐synthesized nucleation layers.

“…Subsequently, the organic components also simultaneously formed CH 3 CHOCO 2 Li Similarly, as shown in Figure 11d, Peng et al fabricated a LiÀ Ag-LiF decorated Li metal anode via a soaking treatment in an Ag + ion precursor solution. [214] The principles behind the formation of the layer on the Li metal anode is based on ion exchange chemistry, forming Li alloys such as Sn, Mo, and Li, and has proven to be a useful and facile approach by which to stabilize Li metal during cycling. The Ag + precursor solution consists of silver bis(trifluoromethanesulfonic) imide (AgTFSI) in a mixed DEC and FEC solvent.…”

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.

“…Furthermore, if the growth of Li dendrites remains uncontrolled, it can deteriorate the Li/electrolyte interface and penetrate the separator, causing a short circuit accompanied by thermal runaway and explosion hazards. [14][15][16] Besides, Li dendrites cause poor Coulombic efficiency (CE) and the gradual increase overpotential and further to fade capacity. [17][18][19][20][21] Thereby, dendritefree Li plating is a prerequisite for the commercialization of LMBs.…”

Lithium (Li) metal anode has been considered as the most promising anode for rechargeable batteries with high energy density owing to its extraordinarily high theoretical specific capacity (3860 mAh g −1) and the lowest negative electrochemical potential (-3.040 V vs. the standard hydrogen electrode). However, the practical applications of the Li metal anode are hampered by several obstacles, such as irrepressible dendritic Li growth and limited Coulombic efficiency (CE) during Li plating/stripping. To improve the application scope of Li metal batteries, it is imperative to develop advanced strategies to figure out these issues. In this Review, we first clarify the fundamental factors that affect the dendrite growth and CE of the Li metal anode. Subsequently, based on the previous theoretical understanding and analysis, recently proposed strategies to suppress dendrite growth and accommodating volume change have been reviewed. In addition, advanced characterization techniques for Li metal anode are included. Finally, a general conclusion and a perspective for the coming development of Li metal anode in practical applications are provided.
