“…Similar impedance diagrams for LATP membranes having an ionically blocking inert electrode on each side have been previously reported by other groups and are widely used to determine the ionic conductivity of LATP membranes [35][36][37]. Equivalent circuits proposed in the literature for impedance of solid-state cells employing LATP membranes can be quite complex and usually include at least one constant phase impedance element [38,39]. The low-frequency intercept with the x axis corresponds to the total active resistance of the LATP membrane R e , which includes resistances of both grain boundaries and grains of polycrystalline LATP membranes.…”

The extremely high theoretical energy density of the lithium-oxygen couple makes it very attractive for nextgeneration battery development. However, there are a number of challenging technical hurdles that must be addressed for LiAir batteries to become a commercial reality. In this article, we demonstrate how the invention of water-stable, solid electrolyte-protected lithium electrodes solves many of these issues and paves the way for the development of aqueous and nonaqueous Li-Air batteries with unprecedented energy densities. We also show data for fully packaged Li-Air cells that achieve more than 800 Wh/kg.

“…A few protection layers were investigated, such as a polymer electrolyte and inorganic thin film. [62][63][64][65][66] For example, Li 1+x+y Al x (Ti,Ge) 2−x Si y P 3−y PO 12 (LATGP) ceramic electrolyte possesses high conductivity and good atmospheric stability but is unstable with Li. A polymer layer of polyethylene oxide with Li(CF 3 SO 2 ) 2 N was casted and then placed between this solid electrolyte and Li anode.…”

“…Li 3−x PO 4−y N y thin film can be sputtered on LATP plate to prevent the reaction between Li metal and LATP. [65,66] In brief, both the introduction of a protective polymer electrolyte and the surface coating of a thin film ionic conductor, which should be stable against Li metal, are effective strategies to employ some chemically unstable solid electrolyte in solidstate Li batteries. However, additional interface and excessive resistance caused by the polymer layer or thin film increase the overall cell 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

Lithium phosphorus oxynitride (LiPON) thin films as solid electrolytes were prepared by radio frequency magnetron sputtering of a Li 3 PO 4 target in ambient nitrogen atmosphere. The influence of radio frequency (rf) power on the structure and the ionic conductivity of LiPON thin films has been investigated. The morphology, composition, structure and ionic conductivity of thin films were characterized by scanning electron microscopy, energy dispersive spectroscopy, X-ray diffraction, X-ray photoelectron spectroscopy and a.c. impedance measurement. It was found that ionic conductivity of LiPON thin films increases with N content in thin films. XPS measurements reveal that ionic conductivity also keeps relativity with the structure of thin films. Higher the N t /N d ratio, higher will be the ionic conductivity of LiPON thin films. And both of them can be improved by increasing rf power from 1⋅5 W/cm 2 to 5⋅5 W/cm 2 .
