In this work, the authors proposed desolvation activation energy as a critical descriptor for the screening of electrolyte additives, establishing a correlation between polarization and desolvation activation energy.

A 3-dimensional N-doped CNT sponge with embedded Fe/Fe₃C nanoparticles as flexible binder-free cathodes for high sulfur loading Li–S batteries.

A free-standing Li–S electrode was fabricated based on the in situ growth of 3DOM MoO₂ on carbonized nonwoven cloth. The Li–S electrode with high sulfur loading exhibits superior storage capability and structural robustness.

N and Co co-doped TiO ₂ nanoparticles grown on carbon fibers are employed to facilitate the formation and stabilization of LiO ₂ .

TiO_2−x@NC with plenty of oxygen vacancies and surface nitrogen-doped carbon coating has been prepared and exhibits excellent cycling stability and superior rate capabilities as an anode material for SIBs.
