Voltage fade is a tricky problem for Li-rich cathodes. In @JJMarie13's latest paper, we follow the oxygen redox reaction to uncover how voltage fade arises. Take a look at @NatureMaterials and watch this space for more from the @CATMAT_FI team soon. nature.com/articles/s4156…
Q. Do Ni-rich cathodes form trapped O2 within them when charged in Li-ion batteries? A. We believe so, and in our latest work we show how. 👇 Credit to @MJuelsholt and Jun Chen for driving this work as part of the @FaradayInst's @CATMAT_FI project. pubs.rsc.org/en/content/art…
We are excited to share our new publication in Nature Chemistry: "Why charging Li–air batteries with current low-voltage mediators is slow and singlet oxygen does not explain degradation" @NatureChemistry @OxfordMaterials #BattChat doi.org/10.1038/s41557…

Wow, thank you #ForbesUnder30! I'm thrilled to be listed among some of Europe's top young scientists and innovators under 30. forbes.com/profile/robert… The future of batteries is coming: Na-ion and beyond! @RAEngNews @FaradayInst @OxfordMaterials @RoyceInstitute @CATMAT_FI
What happens when electrons are removed from oxide ions in battery cathodes? Our new paper in @NatureEnergyJnl reveals that electron holes can delocalise across the O sublattice, underpinning the reversible high voltage O-redox plateau. Read it all here👉nature.com/articles/s4156…
Oxygen redox in a disordered rocksalt structure forms trapped O2 molecules. Even though there is already disorder, the structure must still rearrange to accommodate O2, giving rise to voltage hysteresis. Read @KitMccoll excellent study from @CATMAT_FI in @NatureComms for more!⬇️
