“…This barrier limits entry to the eld and complicates any data science-driven approach to materials synthesis. 50,51 Sample 1 was synthesized according to a previously reported procedure 52 for LPS (Table 1), and Sample 2 was synthesized with a modication of the same procedure, but two different colors were obtained.

“…S1 † shows that Sample 1 is pale white while Sample 2 has a yellow-green hue that has been reported for LPS. 45,52,53 The visual color differences indicate likely unreacted precursors in Sample 1, and X-ray diffraction (XRD) was used to determine the differences. [38][39][40][41]43 Because Li 2 S crystallizes in the cubic space group Fm 3 m, weak reections within the amorphous LPS spectra corresponding to unreacted Li 2 S were expected.…”

“…The total sample mass (2.5 g), mixing media (32 g of 5 mm balls), and ball mill time (40 hours) were kept constant, and the precursors were hand-milled in a mortar and pestle for approximately ten minutes prior to transferring to a 45 mL Zirconia jar. 52 Fig. 2a shows that as the ball milling speed is increased from 350 rpm to 450 rpm, there is a decrease in the residual Li 2 S content from 30 to 19 mol percent; however increasing it further to 500 rpm does not lead to any improvement.…”

“…However, at speeds such as 500 rpm, the caking of the precursors in the ball mill jar becomes prominent, hence limiting the mixing that is required between Li 2 S and P 2 S 5 . Numerous research papers have used 450 rpm as the ball milling speed 25,52,53 and we settled on 450 rpm, noting that it does improve LPS synthesis, but changing the ball milling speed alone does not appear sufficient to obtain pure, amorphous LPS.…”

Commercialization of solid‐state batteries requires the upscaling of the material syntheses as well as the mixing of electrode composites containing the solid electrolyte, cathode active materials, binders, and conductive additives. Inspired by recent literature about the tremendous influence of the employed milling and dispersing procedure on the resulting ionic transport properties of solid ionic conductors and the general performance of all solid‐state batteries, in this review, the underlying physical and mechanochemical processes that influence this processing are discussed. By discussing and combining the theoretical backgrounds of mechanical milling with regard to mechanochemical synthesis and dispersing of particles together with a wide range of examples, a better understanding of the critical parameters attached to mechanical milling of solid electrolytes and solid‐state battery components is provided.

Solid-state lithium metal batteries (SSLMBs) are highly desirable for energy storage because of the urgent need for higher energy density and safer batteries. However, it remains a critical challenge for stable cycling of SSLMBs at low temperature. Here, a highly viscoelastic polyether-b-amide (PEO-b-PA) based composite solid-state electrolyte is proposed through a one-pot melt processing without solvent to address this key process. By adjusting the molar ratio of PEO-b-PA to lithium bis(trifluoromethanesulphonyl)imide (ethylene oxide:Li = 6:1) and adding 20 wt.% succinonitrile, fast Li + transport channel is conducted within the homogeneous polymer electrolyte, which enables its application at ultra-low temperature (−20 to 25 °C). The composite solid-state electrolyte utilizes dynamic hydrogen-bonding domains and ionconducting domains to achieve a low interfacial charge transfer resistance (<600 Ω) at −20 °C and high ionic conductivity (25 °C, 3.7 × 10 −4 S cm −1 ). As a result, the LiFePO 4 |Li battery based on composite electrolyte exhibits outstanding electrochemical performance with 81.5% capacity retention after 1200 cycles at −20 °C and high discharge specific capacities of 141.1 mAh g −1 with high loading (16.1 mg cm −2 ) at 25 °C. Moreover, the solid-state SNCM811|Li cell achieves excellent safety performance under nail penetration test, showing great promise for practical application.
