“…Third, while the lower modulus of sulfide electrolytes might enable very thin, large area sheets of these materials to better withstand the rigors of large scale manufacturing 85,86 , higher modulus oxide sheets might be more prone to failure under the requisite large scale handling and processing conditions. Thin, large area, tape cast sheets are well known to warp, crack, shrink, and delaminate upon heating, particularly when the slurry composition and its processing conditions are not properly optimized [84][85][86][87][88][89][90][91][92][93][94][95][96][97][98] , making higher modulus oxide sheets especially vulnerable to failure during their required high temperature sintering. The consequences of this disparity in mechanical properties is not trivial.…”

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.

“…CO 2 sensors, − catalysts for ethanol conversion, , photocatalysts, − and membranes for seawater desalinization − are other examples of applications. This is a consequence of high ionic conductivity and ion selectivity provided by these materials. ,,, In fact, interest in the crystal structures of NASICONs began at the end of the 1960s. In 1967, Šljukić et al observed the isostructural features of A (I) B 2 (IV) (PO 4 ) 3 phosphates, with A (I) = Li + , Na + , K + , Rb + , and Cs + and B (IV) = Zr 4+ and Hf 4+ .…”

Lithium ion-containing Na + Super Ionic Conductor (NASICON) electrolytes are important materials for new energystorage technologies. The NASICON abbreviation represents several compounds with similar structures applied as solid electrolytes, including those conductors of lithium ions. Different methods have been used to synthesize these materials, as well as innumerous other methods used to form the electrolyte in its final shape. The synthesis methods and processing techniques significantly affect the microstructure and conductivity of the electrolyte as a result. Therefore, this paper provides an overview of the main synthesis methods and processing techniques applied for lithium ion NASICON production. First, a general view of the NASICON structure and the variety of possible compositions will be discussed. Next, the influence of the synthesis methods (e.g., solid-state reaction, sol−gel, polymeric precursor, sol−gel/ electrospinning) and sintering techniques (e.g., conventional, microwave, and Spark Plasma Sintering) will be presented. A special topic will be devoted for glass-ceramics production and evaluation, based on their advantageous ionic conductivity and potentiality for practical use on a large-scale. Moreover, the current results for electrochemical cells simulating the application of these materials in batteries will be presented. Finally, a general point of view of the authors about the future for NASICON electrolytes will be provided, presenting oncoming trends for research.

“…Propylene carbonate, (PC) is a small molecule which is often used in the vinyl polymer industry and consumer products such as adhesives, paints and cosmetics and is soluble in water [35,36]. Its high dielectric constant also makes it useful as a solvent in lithium ion batteries [31,37,38]. Diethyl phthalate (DEP) dissolves organics and many polymers and is a binding agent in cosmetics and fragrances [39].…”

ADMET polymerization in affordable, commercially available, high boiling solvents

Acyclic diene metathesis polymerization is a powerful technique for creating polymers with precise placement of functional groups. However, due to the need to use high vacuum or other methods to remove the volatile ethylene byproduct and drive the reaction forward, traditional solvents are not feasible. Here we demonstrate the use of three cheap, commercially available solvents as a medium for ADMET polymerizations: propylene carbonate, diethyl phthalate, and dioctyl phthalate. We have shown that by using these solvents, we can increase the molecular weights of ADMET-synthesized polyethylene by over 450% as compared to the bulk polymerization as well as reduce polymerization times from 72 h down to 24 and polymerize challenging, solid monomers.
