Check out Lorenz & Niccolò’s paper in ACS Electrochemistry: 12,000 EIS spectra of the SEI in Li–LiFSI–G4 (vs T and [LiFSI]). Using information theory, we show strong correlations among processes—so be cautious when assigning physical meaning. pubs.acs.org/doi/10.1021/ac…

Check out Souhardh’s paper in @Joule_CP where we investigate the lithiation dynamics of metallic interlayers (Ag, Mg, Bi, In) at the negative electrode-argyrodite interface in Li-less solid-state batteries using operando SEM. @FaradayInst @OxfordMaterials cell.com/joule/fulltext…

Check out Matt’s new paper in @NatureComms where we reveal a gradient of LixP species across the SEI formed between Li6PS5Cl and Li, and propose a growth mechanism where Li diffusion through LixP controls SEI growth. Key insight for solid-state batteries. rdcu.be/eL2jH

In Junyi’s new JES paper, we apply perturbation theory to derive a hierarchical asymptotic solution for ion transport under polarization—fitting extended concentration gradients in ORGA without solving the full Newman model. iopscience.iop.org/article/10.114…

Delighted to finally see our review "Understanding solid-state battery electrolytes using atomistic modelling and machine learning" in @NatRevMater This has been a long journey that begun when I was in @SaifulChemistry's group! @accd718 @ben_goldmann nature.com/articles/s4157…

Check out Stephen & Yi’s paper in @ChemMater where we use in-situ Li plating XPS to probe the Li-LiPON SEI. We show a graded structure with reduced species (Li₂O, Li₃N, Li₃P) near Li and partially lithiated (LiₓP) near LiPON. pubs.acs.org/doi/10.1021/ac…

3rd chapter of Emily’s LiOH–LiBr trilogy: we investigate the peritectoid Li₄(OH)₃Br for thermal energy storage. The reported structure is a metastable hydrate. We synthesise the anhydrous phase and measure a melting enthalpy of 263 ± 3 J/g at ~290 °C pubs.acs.org/doi/10.1021/ac…

Check out Emily’s paper! We explore a high-temp phase of Li₃(OH)₂Br (225–275 °C) with 0.12 S/cm Li-ion conductivity at 250 °C. We couldn't stabilise it at RT, forming a less conductive metastable phase. Key implications for the synthesis of Li₂OHBr. pubs.acs.org/doi/10.1021/ac…

Check out Emily’s paper in @ACSMatLett on Li₂OHBr-derived glass solid electrolytes! Key takeaways: [1] hard to make (we used twin-roll quenching) [2] improved ion dynamics [3] unstable under pressure. pubs.acs.org/doi/10.1021/ac…

We are looking for a postdoc @ePSIC_DLS to work on the characterisation of interphases in solid-state batteries using TEM. @FaradayInst @SolbatF vacancies.diamond.ac.uk/vacancy/pdra-i…

We are looking for a postdoc to work on solid-state batteries! Deadline for applications: January 13th tinyurl.com/mvat2bvv

With profound sadness, we announce the passing of Sir Fraser Stoddart, Nobel Laureate and cherished member of @NorthwesternU. His groundbreaking contributions transformed the field of #chemistry and inspired countless scientists worldwide. ➡️ bit.ly/stoddart-in-me…

This study @_Matt_Burton @pastagroup @FaradayInst evaluates methods for producing thin lithium films, emphasizing thermal evaporation as a cost-effective approach while estimating the associated pack costs for solid-state batteries. buff.ly/49DpZG8

Check out Omar’s paper in @ACSEnergyLett where we introduce 0.67m TMAF in [MMIm][TFSI] as a chemically stable F-ion electrolyte with an electrochemical stability window of 4.65 V and an ionic conductivity of 9.53 mS/cm. pubs.acs.org/doi/10.1021/ac…

Check out Max’s paper in @InorgChem we make low-vacancies Cr[Cr(CN)6] via a non-aqueous synthesis and demonstrate an enhanced antiferromagnetic response. One of the most challenging PBAs we have worked with! pubs.acs.org/doi/10.1021/ac…

Explore our Electrochemical energy storage Collection, including this new Communication Article from @pastagroup at @OxfordMaterials 'In situ XPS investigation of the SEI formed on LGPS and LAGP with metallic lithium' #openaccess buff.ly/3NMfJ4b

Check out Yi’s paper in @ChemCommun ! We used in-situ XPS to study the SEI formed by LAGP and LGPS with lithium. LAGP shows slower SEI formation kinetics, possibly due to the mixed ion-electron conductive Li₃P found in LGPS but absent in LAGP. pubs.rsc.org/en/content/art…

Check our Hua’s paper in @CellRepPhysSci where we [1] investigate high-entropy argyrodites as electrolytes in solid-state Li-S batteries [2] identify Li5.7PS4.7Cl0.65Br0.65 as a promising composition [3] show that low local porosity results in increased CCD

Check out Shobhan’s paper on @NatComm where we [1] characterise the effective solid state diffusivities and exchange current densities of graphite and K2Mn[Fe(CN)6] [2] DFN-model a KIB full cell [3] identify the properties that limit rate capability nature.com/articles/s4146…
