1. Localised degradation within sulfide-based all-solid-state electrodes visualised by Raman mapping.

Author

Lim, Jungwoo, Zhou, Yundong, Powell, Rory H., Ates, Tugce, Passerini, Stefano, and Hardwick, Laurence J.

Subjects
RAMAN microscopy, ELECTRODES, SOLID electrolytes, METAL sulfides
Abstract

The distribution of degradation products, before and after cycling, within common sulfide-based solid electrolytes (β-Li3PS4, Li6PS5Cl and Li10GeP2S12) was mapped using Raman microscopy. All composite electrodes displayed the appearance of side reaction products after the initial charge-discharge cycle, located at the site of a LiNi0.6Mn0.2Co0.2O2 particle. [ABSTRACT FROM AUTHOR]

6. Relevance of ion clusters for Li transport at elevated salt concentrations in [Pyr12O1][FTFSI] ionic liquid-based electrolytes.

Author

Brinkkötter, Marc, Giffin, Guinevere A., Moretti, Arianna, Jeong, Sangsik, Passerini, Stefano, and Schönhoff, Monika

Subjects
IONIC liquids, ELECTROPHORESIS, ANODES, NUCLEAR magnetic resonance spectroscopy
Abstract

In binary ionic liquid/Li salt mixtures with the novel asymmetric anion FTFSI, electrophoretic mobility μi values of all ion species were determined using electrophoretic NMR. Li was determined to migrate in negatively charged Li-anion clusters towards the anode. This vehicular transport mechanism was shown to have decreasing relevance at elevated salt concentrations.

9. In situ Raman spectroscopy of carbon-coated ZnFe2O4 anode material in Li-ion batteries – investigation of SEI growth.

Author

Cabo-Fernandez, Laura, Mueller, Franziska, Passerini, Stefano, and Hardwick, Laurence J.

Subjects
ZINC compounds synthesis, RAMAN spectroscopy, LITHIUM-ion batteries, SUPERIONIC conductors, METAL coating, IRON oxide nanoparticles, CARBON, LITHIATION
Abstract

The (de)lithiation process of carbon-coated ZnFe2O4 has been investigated by in situ Raman spectroscopy. Solid electrolyte interphase (SEI) products were detected. Their detection may result from a temporary surface enhancement Raman effect from Zn nanoparticles formed in the conversion reaction at a potential that coincides with SEI formation.

10. Non-aqueous semi-solid flow battery based on Na-ion chemistry. P2-type NaxNi0.22Co0.11Mn0.66O2–NaTi2(PO4)3.

Author

Ventosa, Edgar, Buchholz, Daniel, Klink, Stefan, Flox, Cristina, Chagas, Luciana Gomes, Vaalma, Christoph, Schuhmann, Wolfgang, Passerini, Stefano, and Morante, Joan Ramon

Subjects
FLOW batteries, SODIUM ions, TITANIUM oxides, NICKEL-manganese alloys, COBALT nickel alloys, PHOSPHATE derivatives, OXIDATION-reduction reaction, P-type semiconductors
Abstract

We report the first proof of concept for a non-aqueous semi-solid flow battery (SSFB) based on Na-ion chemistry using P2-type NaxNi0.22Co0.11Mn0.66O2 and NaTi2(PO4)3 as positive and negative electrodes, respectively. This concept opens the door for developing a new low-cost type of non-aqueous semi-solid flow batteries based on the rich chemistry of Na-ion intercalating compounds. [ABSTRACT FROM AUTHOR]
