“…However, using our natural language processing pipeline [63][64][65][66] , we have determined that Ta-doped LLZO remains the most frequently reported variant (the full LLZO corpus used in our analysis can be found online at synthesisproject.org), likely due to its comparatively high ionic conductivity and processability 41 . Recent analysis of the literature by Mahbub, et al, has likewise revealed that c-site modification (of which Ta-doping is one example) of similar lithium garnets is correlated with reduced processing temperatures while still being able to maintain suitably high ionic conductivities 67 . We, therefore, focus our present analysis on Ta-doped LLZO as reported in the work by Han, et al 29 .…”

The pursuit of scalable and manufacturable all-solid-state batteries continues to intensify, motivated by the rapidly increasing demand for safe, dense electrical energy storage. In this Perspective, we describe the numerous, often conflicting, implications of materials choices that have been made in the search for effective mitigations to the interfacial instabilities plaguing solid-state batteries. Specifically, we show that the manufacturing scalability of solid-state batteries can be governed by at least three principal consequences of materials selection: (1) the availability, scaling capacity, and price volatility of the chosen materials' constituents, (2) the manufacturing processes needed to integrate the chosen materials into full cells, and (3) the cell performance that may be practically achieved with the chosen materials and processes. While each of these factors is, in isolation, a pivotal determinant of manufacturing scalability, we show that consideration and optimization of their collective effects and tradeoffs is necessary to more completely chart a scalable pathway to manufacturing. Context & Scale With examples pulled from recent developments in solid-state batteries, we illustrate the consequences of materials choice on materials availability, processing requirements and challenges, and resultant device performance. We demonstrate that while each of these factors is, by itself, essential to understanding manufacturing scalability, joint consideration of all three provides for a more comprehensive understanding of the specific factors that could impede the scale up to production. Much of the recent activity in solidstate battery research has been aimed at mitigating the various interfacial instabilities that currently prevent the fabrication of a low cost, high performance device. With such a wide breadth of options, it can be difficult for researchers to identify the most promising or scalable pathways forward. As such, we aim to empower researchers to make more informed decisions by providing them with insights into how their materials choices are likely to impact the manufacturing scalability of different interfacial mitigation alternatives. In doing so, we hope that generalizable lessons about scalability can be extracted and applied to subsequent challenges in solid-state battery development, thereby accelerating their scale up to manufacturing.

“…Several studies report low-temperature synthesis of Al-doped LLZO below 850 °C [24][25][26][27][28][29], but the calcined powders lacked phase purity or as-synthesized powders required additional milling steps, or long duration sintering (>10 h) to attain dense and conductive pellets. Therefore, producing submicron LLZO powders through less process intensive and low processing temperatures are of importance to prepare dense pellets at low sintering conditions and allowing stable interface contact between LLZO/cathodes to build SSLBs [30][31][32][33].…”

“…For instance, the Li-garnet Li 7 La 3 Zr 2 O 12 (LLZO) is considered one of the promising solid electrolytes to be integrated in Li-metal-based SSBs considering its high room-temperature ionic conductivity (≈mS cm −1 for the cubic phase), high chemical stability toward Li metal (reduction potential of 0.05 V vs Li + /Li), and wide electrochemical stability window. [55,56] Hence, it is not surprising that with the discovery of fast Li-garnet conductors as solid electrolytes for batteries, the idea for their integration in sensors to accelerate tracking of CO 2 soon followed. [57,58] Moreover, prior theoretical and experimental studies of LLZO stability toward humidity and CO 2 exposure [59,60] [58] The sensors offered a fast response time of <60 s at the lowered operation temperature of ≈320 °C, tracking 400-4000 ppm levels of CO 2 .…”

States, these contributors have led to an increased occurrence of natural disasters such as wild fires and hurricanes, which will continue to result in vast environmental climate-change-driven migration and resettling. As a consequence, disparities in terms of quality of life for humans will become much larger, demanding an affordable infrastructure that can locally measure changes in air pollution and minimize climate-change-induced socioeconomic conflicts. Shifts in the local temperature, humidity, and pollutant levels can lead to new diseases and their spread, which in turn requires a careful understanding and measurement of the interplay between these processes. With roughly 91% of the world's population living in urban areas breathing polluted air, [1] solid-state sensors at relatively low cost for the monitoring and control of environmental quality are imperative to preserve air quality, human health, and the environment. In this context, sulfur oxides, SO 2 and SO 3 , make up a sizeable portion of harmful pollutants, which are emitted from residential, manufacturing, and construction sectors through the combustion of sulfur-containing compounds in fossil fuels during oil and gas production and from natural processes such as volcanic eruptions and forest fires (Figure 1a). [4] Sulfur oxides may interact with the environment to cause toxicity, diseases, and environmental decay, playing a significant role in acid rain and having an adverse impact on forests, water, soil, corrosion, and human health (Figure 1b). [5][6][7][8] Moreover, considerable evidence indicates a link between SO 2 exposure and risk of missed abortion in the first trimester of pregnancy, alongside higher likelihood of stillbirth and birth defects due to maternal longterm exposure to pollutants. [9,10] The permissible exposure limit to SO 2 in the air and workplaces is 0.1-10 and 5 ppm, respectively, setting the upper limit for exposure without detrimental effects. [11,12] Conventionally, SO 2 concentrations are measured using one of two optical tracking technologies, IR spectroscopy, or UV absorbance spectroscopy, which are accurate and stable but rather expensive and dependent on bulky instruments (≈50 000 cm 3 ) and thus not suitable for real-time continuous monitoring required in miniaturized applications (Figure 1c). Alternative detection methods include gas chromatography and flame emission spectrometry, which are expensive, time consuming, and demand high power and are thus impractical for real-time monitoring and feedback control on a daily basis. [11,13] Classic chemical sensors integrated in phones, vehicles, and industrial plants monitor the levels of humidity or carbonaceous/oxygen species to track environmental changes. Current projections for the next two decades indicate the strong need to increase the ability of sensors to sense a wider range of chemicals for future electronics not only to continue monitoring environmental changes but also to ensure the health and safety of humans. To achieve this goal, more chemical sensing...
