Phonon RIXS signatures reveal polaron formation in oxygen redox Li- and Na-ion battery cathodes
Vibrationally resolved O K-edge RIXS reveals phonon signatures of strong electron–phonon coupling in oxygen-redox Li- and Na-ion cathodes. Despite different lattice dynamics, both form stabilized oxygen-hole polarons at full charge.
