Ultrathin RuRh Alloy Nanosheets Enable High-Performance Lithium-CO2 Battery

The aprotic Li-CO2 battery with high energy density is an attractive energy-storage technology. However, its development is largely impeded by the sluggish kinetics of CO2 reduction and evolution reactions. Here, we demonstrate a class of ultrathin triangular RuRh alloy nanosheets as an exceptionally active catalyst for greatly accelerating the kinetics of CO2 reduction and evolution reactions and achieving a high-performance Li-CO2 battery.
