Solid state electrolyte systems boasting Li + conductivity of >10 mS cm −1 at room temperature have opened the potential for developing a solid state battery with power and energy densities that are competitive with conventional liquid electrolyte systems. The primary focus of this review is twofold. First, differences in Li penetration resistance in solid state systems are discussed, and kinetic limitations of the solid state interface are highlighted. Second, technological challenges associated with processing such systems in relevant form factors are elucidated, and architectures needed for cell level devices in the context of product development are reviewed. Specific research vectors that provide high value to advancing solid state batteries are outlined and discussed. Solid state battery systems are of great interest because of potential benefits in gravimetric and volumetric energy density, operable temperature range, and safety in comparison to traditional liquid electrolyte based systems. However, unresolved fundamental issues remain in the quest to fully understand the behavior of all-solid batteries, especially in the area of electrochemical interfaces.1 There are also a number of significant engineering challenges that require methodical effort to enable a tangible product. Some transitions from academic laboratories to entrepreneurial efforts attempting to overcome these challenges remain unsuccessful in efforts to bring a product to the market.2,3 Vital parameters that require robust understanding from a product development standpoint are material cost, cell lifetime and shelf life, cell energy density on a volumetric and gravimetric basis, operable capabilities for given temperature conditions, and safety. The advantage of energy density remains to be realized in solid state electrolytes (SSEs) since most studies to date utilize thick SSEs or cathodes with low active loading compared to liquid counterparts. 4,5 Furthermore, the desire to use SSEs in conjunction with Li metal anodes requires understanding and managing the morphology of Li metal plating, which can impact volumetric energy density. Operation at both higher and lower temperature compared to conventional technologies is a significant potential advantage of SSE systems. However, reports of solid state cells achieving parity with traditional systems at room temperature or any other temperature do not currently exist. The safety, specifically decreased flammability, of SSE systems is another potential advantage but requires ongoing validation and study.6 Unlike current liquid electrolyte systems, 7 the manufacturability and material component costs of SSEs have not been well characterized, and thus the value of these features will need to be weighed accordingly with any added cost. Operating lifetime of SSEs capturing intrinsic materials parameters such as voltage stability, 8 as well as catastrophic failure modes such as shorting, 9 have been briefly investigated, but in the absence of high energy density electrode formulations and appli...

“…For most of the oxide glassy electrolytes, the lithium ion conductivity at room temperature is too low to be practical for high energy batteries, normally on the order of 10 −6~1 0 −8 S cm −1 (Tatsumisago et al, 1987;Lee et al, 2002). While in sulfide glasses, high lithium ion conductivities of 10 −3~1 0 −5 S cm −1 at room temperature can be achieved due to high polarizability of sulfur ions, such as Li 2 S-SiS 2 and Li 2 S-P 2 S 5 (Machida and Shigematsu, 2004;Tatsumisago, 2004;Ohtomo et al, 2013c).…”

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.

“…The amount of H 2 S generated from Li 2 SeP 2 S 5 glasses exposed to air was also examined because the chemical stability of Li 2 SeP 2 S 5 solid electrolytes in the atmosphere is concerned. The glass at the composition of Li 3 PS 4 generated the smallest amount of H 2 S in the Li 2 SeP 2 S 5 binary system [19]. The Li 3 PS 4 glass is therefore a promising solid electrolyte for all-solid-state lithium batteries in terms of cell performance and chemical stability.…”

h i g h l i g h t sUse of the Li 3 PS 4 glass electrolyte as an active material was examined. Composite Li 3 PS 4 -AB electrodes were prepared by mechanical milling. All-solid-state cells with the Li 3 PS 4 -AB electrode successfully operated. a b s t r a c tFor increasing energy densities of all-solid-state cells, utilizing solid electrolytes in the electrode layer as an active material is useful. Favorable electron conduction paths to the Li 3 PS 4 glass electrolyte were formed by mechanical milling with AB as the conductive additives. The all-solid-state cells with Li 3 PS 4 glass only or mixture prepared by grinding the Li 3 PS 4 glass and AB as a positive electrode did not work. On the other hand, the cell with Li 3 PS 4 -AB composite electrodes prepared by milling was successfully charged and then discharged. Initial charge capacity of the cell with the Li 3 PS 4 -AB composite electrode was 220 mAh g À1 at 0.064 mA cm À2 . Open circuit voltage of the cell was 2.6 V vs. Li, which was higher than that with Li 2 S active material. In the cell with the Li 2 SeLi 3 PS 4 -AB composite electrode, the Li 3 PS 4 glass functioned as not only Li þ ion conductive paths to Li 2 S but also active material itself, suggesting that the use of the solid electrolytes as active materials in electrode layers is useful for increasing reversible capacity per gram of a positive electrode.
