Co-doped CeO2 catalyzes bidirectional sulfur redox reactions for high-performance lithium-sulfur batteries.

To address the issue of slow kinetics in the sulfur reduction reaction/sulfur oxidation reaction in lithium-sulfur batteries (LSBs), in this work, cobalt was doped into CeO2 composite carbon nanotubes by ion exchange as functional intercalation of LSBs. Cobalt doping enhances polysulfide trapping and ion/electron trans...
