“…As shown in Figure 6a, Wang's group suggested a lithium phosphorus oxynitride (LiPON) coating layer, formed nitrogen plasmaassisted deposition of electron-beam reacting evaporation. [179] The developed LiPON layer is a dense, interfacial stable, mechanically robust, has high ionic conductivity, and can cover the lithium metal on a large scale. To understand the electrochemical properties, electrochemical impedance spectroscopy measurements and calculations were carried out, which revealed that the LiPON coating layer shows high ionic conductivity as a passivation layer, as well as excellent mechanical properties.…”

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.

“…Over the past 4 decades, various modification methods have been applied to tackle these obstructive problems. In consideration of the poor mechanical property and chemical instability of original SEI layer, surface modification is carried out to enhance the SEI formation and suppress dendrite growth through electrolyte regulation (Cs + , Li halide, LiNO 3 , and NaAlCl 4 ·2SO 2 ), artificial SEI layer (LiPON, atomic Al 2 O 3 layer deposition, Nafion‐LiCl, 1,4‐dioxacyclohexane (DOX), phosphorene), and concentrated electrolyte (concentrated NaFSI‐glyme, 4 m LiTFSI), etc. However, due to the “hostless” characteristics of the alkali metal electrode, this kind of method cannot withstand the large volume change generated during the cycling and eventually lead to the rupture of the SEI film.…”

(1 of 10)Uncontrollable dendritic behavior and infinite volume expansion in alkali metal anode results in the severe safety hazards and short lifespan for high-energy batteries. Constructing a stable host with superior Na/Li-philic properties is a prerequisite for commercialization. Here, it is demonstrated that the small Gibbs free energy change in the reaction between metal oxide (Co 3 O 4 , SnO 2 , and CuO) and alkali metal is key for metal infusion. The as-prepared hierarchical Co 3 O 4 nanofiber-carbon sheet (CS) skeleton shows improved wettability toward molten Li/Na. The 3D carbon sheet serves as a primary framework, offering adequate lithium nucleation sites and sufficient electrolyte/electrode contact for fast charge transfer. The secondary framework of Co/Li 2 O nanofibers provides physical confinement of deposited Li and further redistributes the Li + flux on each carbon fiber, which is verified by COMSOL Multiphysics simulations. Due to the uniform deposition behavior and near-zero volume change, modified symmetrical Li/Li cells can operate under an ultrahigh current density of 20 mA cm −2 for more than 120 cycles. When paired with LiFePO 4 cathodes, the Li/Co-CS cell shows low polarization and 88.4% capacity retention after 200 cycles under 2 C. Convincing improvement can also be observed in Na/Co-CS symmetrical cells applying NaClO 4 -based electrolyte. These results illustrate a significant improvement in developing safe and stable alkali metal batteries.

“…Moreover, the shuttle of polysuldes during the charge-discharge cycle results in severe problems, such as a low coulombic efficiency and poor cycling stability. 1,2 The theoretical energy density of the Li-air battery system is higher, reaching 3608 W h kg À1 . Therefore, Li-air batteries still have a short cycle life.…”

5 Al 0.5 Ge 1.5 (PO 4 ) 3 (LAGP) is an inorganic solid electrolyte with a Na superionic conductor (NASICON) structure that provides a channel for lithium ion transport. We coated LAGP particles on one side of a polypropylene (PP) separator film to improve the ionic conductivity of the separator, and waterdispersed polyvinylidene fluoride-hexafluoropropylene (PVDF-HFP) on the other side to reduce the interfacial resistance between the separator and the lithium metal anode. The results show that the LAGP/PP/PVDF-HFP separator has a high ionic conductivity (1.06 mS cm À1 ) at room temperature (PP separator: 0.70 mS cm À1 ), and an electrochemical window of 5.2 V (vs. Li + /Li). The capacity retention of a NCM|LAGP/PP/PVDF-HFP|graphite full cell is 81.0% after 300 charge-discharge cycles at 0.2C. When used in a NCM|LAGP/PP/PVDF-HFP|Li half-cell system, the initial discharge capacity is 172.5 mA h g À1 at 0.2C, and the capacity retention is 83.2% after 300 cycles. More significantly, the surface of the Li anode is smooth and flat after 200 cycles. The interface resistance increased from 7 to 109 U after 100 cycles at 0.2C. This indicates that the synergistic effect of the asymmetric coated LAGP and PVDF-HFP is beneficial to inhibiting the growth of lithium dendrites in the battery and reduces the interface resistance.
