Uniformly Dispersed Fe Clusters on Nitrogen-Doped Carbon Aerogel as a High-Performance Cathode Catalyst for Li-O2 Batteries
Lithium-oxygen (Li-O2) batteries are a compelling next-generation energy storage candidate owing to their ultrahigh theoretical specific energy, but their practical deployment is critically limited by sluggish cathodic oxygen reduction/evolution kinetics, severe polarization, and poor cyclability. Here, we design a com...
