Hexagonal Close-Packed RuCo Alloys Modulate Li2O2 Formation and Decomposition Pathways in Lithium–Oxygen Batteries
Aprotic lithium–oxygen (Li–O2) batteries suffer from large voltage hysteresis and inferior reversibility, originating from the sluggish redox kinetics of insulating Li2O2. Here, we incorporate Ru atoms into Co nanoparticles encapsulated within carbon nanotubes and induce a phase transition from a face-centered cubic...
