Visualization of O-O peroxo-like dimers in high-capacity layered oxides for Li-ion batteries
Eric McCalla,Artem M. Abakumov,Artem M. Abakumov,Matthieu Saubanère,Matthieu Saubanère,Dominique Foix,Dominique Foix,Erik J. Berg,Gwenaëlle Rousse,Gwenaëlle Rousse,Gwenaëlle Rousse,Marie-Liesse Doublet,Marie-Liesse Doublet,Danielle Gonbeau,Danielle Gonbeau,Petr Novák,Gustaaf Van Tendeloo,Robert Dominko,Jean-Marie Tarascon +18 more
TL;DR: The fundamental relation between the anionic redox process and the evolution of the O-O bonding in layered oxides is established, and the design of safe and long-lasting batteries requires an understanding of the physical and chemical changes that occur during redox processes.

The intriguing question of anionic redox in high-energy density cathodes for Li-ion batteries
Matthieu Saubanère,Matthieu Saubanère,Eric McCalla,Eric McCalla,Jean-Marie Tarascon,Jean-Marie Tarascon,Marie-Liesse Doublet,Marie-Liesse Doublet +7 more
TL;DR: In this paper, the ability of Li-ion batteries to stabilize the oxygen holes generated by Li-removal and to achieve a reversible oxo-to peroxo-like (2O2−/(O2)n−) transformation is elucidated by means of a metal-driven reductive coupling mechanism.

Abakumov,Gustaaf Van Tendeloo,Jean-Marie Tarascon,Jean-Marie Tarascon +23 more
TL;DR: In this paper, the authors reported the electrochemical properties of a Na-rich phase Na2IrO3 which can reversibly cycle 1.5 Na+ per formula unit while not suffering from oxygen release nor cationic migrations.
X-ray Photoemission Spectroscopy Study of Cationic and Anionic Redox Processes in High-Capacity Li-Ion Battery Layered-Oxide Electrodes
Dominique Foix,Mariyappan Sathiya,Eric McCalla,Eric McCalla,Jean-Marie Tarascon,Danielle Gonbeau +5 more
TL;DR: In this article, the authors report on the redox mechanisms in high-capacity Li-rich materials Li2Ru1-xMxO3 and Li2Ir1-oxO3 by combining X-ray photoemission spectroscopy (XPS) core peaks and valence intensity analyses.
