Co-Fe dual-atom isolated in N-doped graphydine as an efficient sulfur conversion catalyst in Li-S batteries

Lithium-sulfur (Li-S) batteries have garnered considerable attention as a prospective energy storage device for the future due to their exceptionally high theoretical energy density. Unfortunately, sluggish sulfur reactions create a bottleneck in Li–S batteries, hindering their ability to deliver al...
