“…Despite earlier works that claimed LLZ to be chemically stable against moisture [3,5], in line with reports for most Li + ion conducting oxides [6], further research has found that LLZ is chemically unstable against moisture where lithium ions in LLZ can be exchanged by protons under ambient air humidity [7,8] or immersion in water [8][9][10]. This was initially overlooked as up to a substantial Li + /H + exchange, the garnet-related structure is preserved.…”

“…Garnet-like solid electrolytes are chemically stable with Li metal and have a high electrochemical window of up to 6 V. [36][37][38][39][40][41][42][43][44][45]67] However, many studies demonstrated that LLZO is unstable in air [68][69][70][71][72] mainly because of water vapor and carbon dioxide, and thus its body integrity and ionic conductivity are considerably affected. A small amount of Li 2 CO 3 forms on the surface of www.advenergymat.de LLZO ceramics and greatly increases interfacial resistance.…”

batteries based on intercalation materials cannot meet the demands of long-distance transport (i.e., >300 km).Recently, interest in Li-air [4][5][6] (or Li-O 2 as oxygen is the cathode active component) and Li-S batteries [7][8][9] has increased because of their high theoretical capacities and energy densities, which are suitable for remote transportation. Abraham and Jiang introduced the first rechargeable Li-O 2 battery in 1996, [10] although it drew little interest until Bruce and co-workers proved the rechargeability of Li 2 O 2 . [11] Li-O 2 cells possess significant strength because oxygen gas can be obtained from ambient air. Li-ions react with oxygen according to Equation (1), and Li 2 O 2 is the discharge product with an equilibrium potential of 2.96 V, delivering a large specific energy of 3600 W h kg −1 . Investigations on Li-S cell date back to the 1940s. The insulating nature of sulfur, Li 2 S 2 , and Li 2 S and the solubility of polysulfide intermediates greatly hinder its development. Fortunately, recent studies on new electrolytes and nanostructured material design provide merits and opportunities in developing Li-S batteries. Similar to Li-O 2 batteries, Li-S batteries, which contain inexpensive and abundant sulfur as positive electrode material, produce an average voltage of 2.15 V and possess a theoretical energy density of up to 2600 W h kg −1 , as further indicated by Equation (2). Many studies showed that intermediate polysulfide is produced during the discharge process where Li 2 S is formed as the final product. Typically, Li-O 2 and Li-S batteries both adopt Li metal as anode. The reason is that Li possesses the largest capacity (3860 mA h g −1 ) and the lowest negative electrochemical potential (−3.04 V) versus standard hydrogen electrodes. Thus, Li-O 2 and Li-S batteries are considered to be promising next-generation energy storage systems for PEVs and HEVs However, despite the advantages of Li-O 2 and Li-S batteries, they exhibit ignitability, toxicity, liquid leakage, and volatilization because of their organic liquid electrolyte components. Moreover, Li dendrites form during cycling, resulting in internal short circuit that leads to combustion and even cell explosion. [12,13] More seriously, the charging process in Li-air

“…Owing to its high ionic conductivity, excellent stability with Li and wide electrochemical voltage window (Ishiguro et al, 2013;Jin and McGinn, 2013b), LLZO has been successfully used to fabricate all-solid-state lithium batteries. Jin and McGinn (2013a) reported a Cu 0.1 V 2 O 5 /LLZO/Li all-solid-state battery, which exhibited an initial discharging capacity of 93 mA h g −1 at 10 µA cm −2 (at 50°C).…”

The review presents an overview of the recent advances in inorganic solid lithium ion conductors, which are of great interest as solid electrolytes in all-solid-state lithium batteries. It is focused on two major categories: crystalline electrolytes and glass-based electrolytes. Important systems such as thio-LISICON Li 10 SnP 2 S 12 , garnet Li 7 La 3 Zr 2 O 12 , perovskite Li 3x La (2/3) x TiO 3 , NASICON Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 , and glass-ceramic xLi 2 S·(1 − x )P − 2 S 5 and their progress are described in great detail. Meanwhile, the review discusses different ongoing strategies on enhancing conductivity, optimizing electrolyte/electrode interface, and improving cell performance.
