Inhibition of oxygen dimerization by local symmetry tuning in Li-rich layered oxides for improved stability

Li-rich layered oxide cathodes show high capacities in Li-ion batteries but suffer from structural degradation via O–O dimerization. Here, the authors present local-symmetry-tuned Li2RuO3 with oxygen redox involving a telescopic O–Ru–O configuration avoiding O2 release, enhancing cycling stability....
