Magnesiothermically Synthesized TiO-Decorated 3D N-Doped Graphitized Porous Carbon as a Multifunctional Sulfur Host for Li–S Batteries

with a corresponding CE of 99% during the first discharge cycle. Density functional theory simulations confirm the strong adsorption of LiPSs and catalytic activity of TiO, highlighting its potential as a multifunctional host for high-performance lithium-sulfur batteries.
