“…The insertion of the composite film between the anode and the separator mitigates the parasitic reaction caused by oxygen crossover, acquiring low interfacial impedance values and enhanced stability of the LIOB. Consideration of the high ionic conductivity and excellent mechanical property of the ceramic materials, a water‐stable and water‐impermeable Li‐ion conducting solid electrolyte layer of Li 1.3 Al 0.5 Nb 0.2 Ti 1.3 (PO 4 ) 3 (LANTP) was constructed by Shang and colleagues . As shown in Figure a, the water permeation tests indicate the LANTP layer can efficiently prevent moisture from infiltrating with epoxy resin filled in open pores.…”

Rechargeable LiÀ O 2 batteries play an increasing important role as energy storage devices, which have both, a high capacity anode and a cathode using an inexhaustible resource. As a key component in LiÀ O 2 batteries, the Li-metal anode suffers from major drawbacks related to Li dendrite formation and SEI layer growth, which are also major issues for Li-metal rechargeable batteries. This review presents an overview on the scientific challenges, fundamental mechanisms and modification strategies of Li-metal anodes for LiÀ O 2 batteries. Firstly, basic principles and challenges on Li-metal anodes are briefly retrospected. We further summarize and categorize the prevailing characterization techniques based on Li dendrite morphology characterization and SEI composition analysis. The up-to-date development of in-situ and operando characterization is also included. Following the obtained insights, effective protection/modification strategies towards practical application for LiÀ O 2 batteries are presented. Furthermore, we highlight the significance of advanced characterization techniques in interrogating the buried keys for solving practical hindrances for LiÀ O 2 batteries. The comprehensive characterization and analysis of Li anodes, cathodes, and electrolytes by various methods together with the development of novel techniques are expected to be indispensable to gain a thorough understanding of the battery operation and for offering guidelines for their practical development.

research, aqueous electrolytes were occasionally employed for the investigation of cathode materials instead of the conventional nonaqueous electrolytes. [9,10] It was discussed that the simplicity of an aqueous electrolyte provides a better opportunity for the fundamental studies of the process of intercalation/deintercalation of Li-ions as opposed to the nonaqueous electrolytes. For instance, although the formation of solid electrolyte interphase (SEI) is of utmost importance for the cyclability of LIB, the significant role of the electrolyte does not allow to exclusively study the electrochemical behavior of the electrode material under consideration. The current research has specifically targeted the development of ARLBs, but in practice, most of the recent papers have followed the same line of research in investigating a limited range of cathode and anode materials in the same aqueous electrolytes. [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28] A possible reason is that the key advantage of ARLBs was low cost, and thus, the focus was limited to a few inexpensive materials (e.g., lithium salts). Aqueous electrolytes are definitely excellent choices for the fundamental studies of electrode materials, but the practical development of ARLBs needs overcoming the key obstacles rather than finding more cathode materials.In any case, aqueous electrolytes were occasionally used during the 2000s by various research groups, but there was no vivid plan for the development of ARLBs. These works have been extensively reviewed before, [29][30][31][32][33] and it is not aimed to repeat the general works on aqueous electrolytes here. During the recent years, new opportunities have been introduced, which can extend the stable potential window of aqueous electrolyte to the range of 3-4 V. Upon this advancement, aqueous electrolytes can fairly compete with the conventional nonaqueous electrolytes for the fabrication of cheaper and safer LIBs. On the other hand, novel designs such as self-healing [34] or flexible [16,35,36] ARLBs have paved the path for new practical potentials of aqueous electrolytes. The present paper specifically focuses on the recent advancements and attempts to foster the strategy of research to shed light on the pathway of this emerging area of research. Two factors are directly responsible for achieving a high energy density, the specific capacity, and the cell voltage. Since the former is not massively controlled by the electrolyte and the specific capacity of most electroactive Owing to the high voltage of lithium-ion batteries (LIBs), the dominating electrolyte is non-aqueous. The idea of an aqueous rechargeable lithium battery (ARLB) dates back to 1994, but it had attracted little attention due to the narrow stable potential window of aqueous electrolytes, which results in low energy density. However, aqueous electrolytes were employed during the 2000s for the fundamental studies of electrode materials in the absence of side reactions such as the decomposition of organic spec...

“…Figure 8 shows the impedance profiles of the Li/(LiFSI-2G4)-50 vol% DOL/LAGTP-E-LiCl/saturated LiOH and LiCl aqueous solution/KB, air cell compared with that of a cell with LAGTP-E. These impedance profiles show two semicircles; the semicircle at high frequency corresponds to the grain boundary resistance of the solid electrolyte and that at low frequency to the interface resistance with lithium metal (Nemori et al, 2018). The cell with LAGTP-E-LiCl showed a lower cell resistance of ∼167 compared with that of the cell with LAGTP-E (∼200 ), where the contact area of the lithium electrode with the interlayer electrolyte was 1.13 cm 2 , that of the interlayer electrolyte with the solid electrolyte was 1.76 cm 2 , and that of the catholyte with the air electrode was 2.0 cm 2 .…”

Aqueous lithium-air batteries are one of the most promising batteries for electric vehicles because of its high energy and power density. The battery system consists of a lithium anode and an aqueous solution catholyte, which are separated by a water-stable lithiumion-conducting solid electrolyte, and an air electrode. The theoretical energy density of this system is 1,910 W h kg −1 , which is around five times higher than that of conventional lithium-ion batteries. A key component of this system is the water-stable lithium-ion-conducting solid electrolyte. In this work, we have developed a water-stable and water-impermeable solid electrolyte with a high lithium-ion conductivity of around 10 −3 S cm −1 at room temperature by the addition of epoxy resin and LiCl into a tapecast NASICON-type Li 1. 4 Al 0. 4 Ge 0. 2 Ti 1. 4 (PO 4) 3 film. The aqueous lithium-air battery with the solid electrolyte separator was successfully cycled at 0.5 mA cm −2 and 25 • C in an air atmosphere.
