Energy storage materials are finding increasing applications in our daily lives, for devices such as mobile phones and electric vehicles. Current commercial batteries use flammable liquid electrolytes, which are unsafe, toxic, and environmentally unfriendly with low chemical stability. Recently, solid electrolytes have been extensively studied as alternative electrolytes to address these shortcomings. Herein, we report the early history, synthesis and characterization, mechanical properties, and Li+ ion transport mechanisms of inorganic sulfide and oxide electrolytes. Furthermore, we highlight the importance of the fabrication technology and experimental conditions, such as the effects of pressure and operating parameters, on the electrochemical performance of all-solid-state Li batteries. In particular, we emphasize promising electrolyte systems based on sulfides and argyrodites, such as LiPS5Cl and β-Li3PS4, oxide electrolytes, bare and doped Li7La3Zr2O12 garnet, NASICON-type structures, and perovskite electrolyte materials. Moreover, we discuss the present and future challenges that all-solid-state batteries face for large-scale industrial applications.

“…One remarkable advantage of sulfide‐based SSEs is their softness, and this flexibility makes it possible to reversibly deform at the metal/SSE interface as the metal expands, maintaining performance during cycling. [ 15 ] However, these electrolytes are air sensitive enough to evolve gas during oxidation. Another intrinsic problem is that Na metal thermodynamically reacts with most thiophosphates to form poor ion‐conducting products (e.g., Na 2 S).…”

All-solid-state metal batteries (ASSMBs) are attracting much attention due to their cost effectiveness, enhanced safety, room-temperature performance and high theoretical specific capacity. However, the alkali metal anodes (such as Li and Na) are active enough to react with most solid-state electrolytes (SSEs), leading to detrimental reactions at the metal-SSE interface. In this work, a molecular layer deposition (MLD) alucone film is employed to stabilize the active Na anode/electrolyte interface in the ASSMBs, limiting the decomposition of the sulfide-based electrolytes (Na 3 SbS 4 and Na 3 PS 4 ) and Na dendrite growth. Such a strategy effectively improves the room-temperature full battery performance as well as cycling stability for over 475 h in Na-Na symmetric cells. The modified interface is further characterized by X-ray photoelectron spectroscopy (XPS) depth profiling, which provides spatially resolved evidence of the synergistic effect between the dendrite-suppressed sodiated alucone and the insulating unsodiated alucone. The coupled layers reinforce the protection of the Na metal/electrolyte interface. Therefore, alucone is identified as an effective and bifunctional coating material for the enhancement of the metal/electrolyte interfacial stability, paving the way for rapid development and wide application of high-energy ASSMBs.

“…However, in the cell assembled with a bare lithium anode, the total resistance of the cell increases substantially possibly due to the formation of a layer composed of Li 2 S and Li 3 P phases as Li 7 P 3 S 11 decomposed. [ 46,52 ] Continuous increase in the thickness of the SEI layer due to the degradation of solid electrolytes would inevitably increase the total impedance of the cell as evidenced in the cell assembled with bare lithium anode.…”

Regardless of the battery type, Li-ion (sulfur) or Li-O 2 , it is rational to consider the lithium metal as the anode material in these batteries due to several aspects. First, it is the lightest solid (0.534 g cm −3) in the whole periodic table and has the lowest electrode potential with −3.04 V. [4,5] Second, as a pure lithium source, an intercalation or conversion reaction media is not necessarily required in batteries with lithium anodes. Overall, lithium metal has a theoretical specific capacity of ≈3860 mAh g −1. [4] However, many problems arising from the highly reactive nature of lithium metals, namely; 1) uncontrollable dendrite formation during lithium deposition\dissolution and 2) unstable solid-electrolyte interface (SEI) layer formation, restricts its use in secondary batteries. All-solid-state LIBs (ASSLIBs) are now emerging systems to replace LIBs with liquid electrolytes and are free of the aforementioned problems in certain aspects. Solid-electrolytes were shown to greatly suppress the formation of lithium dendrites. However, the formation of an unstable SEI layer still exists in ASSLIBs. Although solid electrolytes with lithium-ion conductivity on the order of liquid electrolytes have been synthesized, [6-9] their adaption into a cell with lithium anode is hindered due to the formation of unstable SEI layer. A stable SEI layer has to meet several criteria. First, an SEI layer has to be composed of electronically (ionically) insulating (conducting) phases. Besides, the layer should be thin and dense enough so that the total impedance of the system does not increase due to the low ionic conductivity of the layer. Unfortunately, only a few numbers of solid electrolytes exist that satisfies the above mentioned criteria. One plausible way to avoid the self-formation of the unstable SEI layer is to coat the lithium anode with the phases having desired properties. By coating lithium anode; 1) the contact between anode and electrolyte can be increased due to better wetting, 2) dendrite formation can be eliminated, and 3) electrolyte decomposition can be prevented. Li 3 N coating was shown to increase capacity retention in our previous study. [10] However, the small grain sizes (<160 nm), and weak interconnection is not capable of suppressing Li metal dendrites for long cycles. [11] Moreover, the voltage stability window of Li 3 N is only ≈0.45 V and unstable to reduction (≤2.4 V vs Li/Li +) which is low for practical applications. [12] An ultrathin Al 2 O 3 layer was shown to increase the wetting and electrochemical stability of the garnet-type solid All-solid-state lithium-ion batteries are considered the next-generation energy storage systems. However, certain problems arise from the degradation of anode-electrolyte interface hindering their use especially when lithium is used as an anode. Herein, lithium metal anode surface is modified by an artificial 2H-MoS 2 layer to prevent the contact between highly reactive lithium and solid electrolyte without sacrificing the lithium ion transport. The stabili...
