High-entropy nanoparticle constructed porous honeycomb as a 3D sulfur host for lithium polysulfide adsorption and catalytic conversion in Li–S batteries

A porous honeycomb-like sulfur host was engineered using oxidized six-element HEA nanoparticles (MgCrMnFeCoNi–O), offering excellent lithium polysulfide adsorption ability and catalytic activity toward the conversion of sulfur species.
