“…Na 2 Zn 1– x Si 1– x A 2 x O 4 substituted with 22 elements was synthesized and analyzed via high-throughput powder X-ray diffraction (XRD). At x = 0.1, Na 2 Zr 1.9 In 0.1 Si 1.9 A 3.8 O 4 exhibits the highest ionic conductivity (2.226 × 10 –3 S/cm) and electrochemical stability (down to 0.8 V) vs Na, which is compatible with some anodes . These studies have helped identify NASICON candidates that meet the conditions of high ionic conductivity and electrochemical stability.…”

Na-ion batteries are considered a promising alternative to the analogous Li-ion batteries because of their low manufacturing cost, large abundance, and similar chemical/electrochemical properties. In particular, research on Na-ion solid electrolytes, which resolve the flammability issues associated with liquid electrolytes and increase the energy density obtained using a particular metal anode, is rapidly growing. However, the ionic conductivities of these materials are lower than those of liquids. We present a novel classification approach based on machine learning for identifying Na superionic conductor (NASICON) materials with outstanding ionic conductivities. We obtained new features based on chemical descriptors such as Na content, elemental radii, and electronegativity. We then classified 3573 NASICON structures by implementing the ensemble model of gradient boosting algorithms, with an average prediction accuracy of 84.2%. We further validated the thermodynamic stability and ionic conductivity values of the materials classified as superionic materials by employing density functional theory calculations and ab initio molecular dynamics simulations.

“…have redox activity, which directly leads to the decomposition of electrolytes in SMB. Therefore, Zhang et al used alucone films deposited on Na foil to separate Na metal and sulfide electrolytes (as shown in Figure 7F) [129] . In the absence of MLD coating, continuous protruding particles appeared on the surface of the exposed Na metal electrode, indicating the growth of Na dendrites.…”

Sodium metal batteries (SMBs), benefiting from their low cost and high energy densities, have drawn considerable interest as large-scale energy storage devices. However, uncontrollable dendritic formation of sodium metal anodes (SMAs) caused by inhomogeneous deposition of Na+ severely decreases the Coulombic efficiency, leads to short cycling life, and poses potential safety hazards, dragging SMBs out of practical applications. Electrolytes are attracting massive attention for not only providing ion transport channels but also exhibiting vital effects on interfacial compatibility and dendrite growth. In fact, the as-formed solid electrolyte interphase (SEI) has a great influence on the deposition and stripping process of SMAs. Moreover, Na plating process is accompanied by the generation of SEI, in which the electrolyte plays a vital role. Nevertheless, until now, the interaction among electrolyte-SEI-sodium dendrite has rarely been summarized. Herein, a fundamental understanding of sodium dendrite is concluded and the influence of the electrolyte and interface on Na+ deposition is emphasized. Furthermore, the outlook for constructing dendrite-inhibited SMAs is suggested.

“…[7][8][9][10] Libraries of materials have also been produced as spots on substrates 11 and by ink-jet printing 12,13 but the amounts of material produced are very small (mg scale) and the applicability is limited by problems of reaction with the substrate during calcination and of the substrate appearing in the subsequent X-ray diffraction analysis. Sol-gel based methods, when this synthesis chemistry is appropriate for the system under study, are ideally suited to the high-throughput liquid dispensing robots developed for the pharmaceutical industry and have been applied to the discovery of new battery electrolyte materials, 14,15 metal halide perovskites 16 and work has been done to introduce solid handling into a highthroughput ceramic workow. 17 Continuous hydrothermal ow synthesis has also been used to prepare libraries of powdered oxides for oxygen evolution reaction electrocatalysts, producing individual sample sizes of ∼3 g. 18 Traditional solid-state synthesis is challenging to achieve in a high throughput workow, as the parallelisation of mixing, grinding and pressing many 10's of solid samples demands bespoke solutions [19][20][21] or multiple milling tools for avoidance of media contamination.…”
