The role of O2 in O-redox cathodes for Li-ion batteries

Robert A. House et al.

Summary: This study explores the mechanisms and impacts of oxygen redox in lithium-ion batteries, proposing a unified model to reduce instability caused by oxygen redox and provide strategies for achieving more reversible, high energy density cathodes.

Synthetic Pathway Determines the Nonequilibrium Crystallography of Li- and Mn-Rich Layered Oxide Cathode Materials

Ashok S. Menon et al.

Summary: Li- and Mn-rich layered oxides hold promise as electrode materials for future Li-ion batteries, but their crystallography remains inaccurately described, with the synthetic route having a direct impact on the crystal structure. Clarifying structural ambiguities is crucial for understanding electrochemical performance and anionic redox behavior.

Nanostructure Transformation as a Signature of Oxygen Redox in Li-Rich 3d and 4d Cathodes

Antonin Grenier et al.

Summary: LRNMC cathodes have higher energy storage capacity, but during O oxidation, nanoscale domains of lower electron density are formed within the cathode structure. The observation of nanopores during O oxidation, which is partially reversible, is a common feature in Li-rich systems like Li2RuO3 and Li1.3Nb0.3Mn0.4O2, but not present in traditional cathode materials such as stoichiometric NMC and NCA.

Covalency does not suppress O2 formation in 4d and 5d Li-rich O-redox cathodes

Robert A. House et al.

Summary: Recent findings suggest that Li-rich transition metal oxides undergo O-redox, forming molecular oxygen trapped in the particles during oxidation. This phenomenon occurs across 3d, 4d, and 5d transition metal oxides, indicating a greater covalency in the 4d and 5d compounds does not stabilize peroxo-like species. High resolution RIXS and XAS data for Li2IrO3 support a charge compensation mechanism associated primarily with Ir redox without evidence of O-O dimerization.
