Weak σ–π–σ Interaction Stabilizes Oxygen Redox in Li-Rich Cathodes

[Research Background] The key to controlling the oxygen oxidation-reduction chemistry is to adjust the chemical environment of the lattice oxygen with redox activity, namely the Li2MnO3-like domains.Recent studies have shown that aggregated large-sizeLi2MnO3-like domains can lead to irreversible TM migration and oxygen oxidation-reduction, resulting in notorious capacity fading and voltage decay. According to Pauling’s rules, … Read more
