Delighted to share another work from my time with Peter Bruce, out now in EES @rsc.org
We look at how multi-length scale disorder shapes Li-ion transport in lithium argyrodites!

How multi-length scale disorder shapes ion transport in lithium argyrodites The rate performance of all-solid-state batteries can be limited by the low conductivity of the solid electrolyte in the composite cathode. A conductivity of 10 mS cm−1 is required, which exceeds that of many solid electrolytes. This limitation can be attributed to intra- and inter-grain ion transport. Understandin

Happy to share our recent work investigating the effect of short range order on ion transport;

Lithium Antiperovskite-Derived Glass Solid Electrolytes In this paper, we report the synthesis of Li2OHX (X = Br, Cl)-based glasses. These glasses were found to be challenging to synthesize, requiring extreme cooling rates achievable only by a twin-roll qu...

The Pasta Group (www.pastagroup.org) has published a new paper on Li2OHBr-derived glass solid electrolytes.

Key takeaways: [1] hard to make (they used twin-roll quenching) [2] improved ion dynamics, & [3] unstable under pressure.

Always fun to visit CERN. @cern.bsky.social
