Modulating the d-Band Center of RuO via Ni Incorporation for Efficient and Durable Li-O batteries.

Rechargeable Li-O batteries (LOBs) are considered as one of the most promising candidates for new-generation energy storage devices. One of major impediments is the poor cycle stability derived from the sluggish reaction kinetics of unreliable cathode catalysts, hindering the commercial application of LOBs. Therefore, the rational design of efficient and durable catalysts is critical for LOBs.
