Anomalous metal segregation in lithium-rich material provides design rules for stable cathode in lithium-ion battery

The authors show that after cycling the model cathode material Li2Ru0.5Mn0.5O3 undergoes ruthenium segregation and even exsolution at the reconstructed oxide surface, which triggers a progressive degradation process. The insights enable new dimensions in choosing dopants for stabilized cathode surfa...
