A strontium ferrite modified separator for adsorption and catalytic conversion of polysulfides for excellent lithium–sulfur batteries

Abstract

Bimetallic oxide SrFe12O19/AB composite separator regulates lithium polysulfides to realize sustainable lithium-sulfur batteries.

A well-dispersed OV-NiCo2O4 nanosphere modified separator for Li–S batteries

“…Compared with the use of a PP battery, the O V -NiCo 2 O 4 //PP battery exhibits a higher peak current, which means that O V -NiCo 2 O 4 is conducive to enhancing the redox kinetics of LiPSs and reducing polarization. 25 The Tafel slope is an effective index to measure the catalytic activity. The lower the Tafel slope, the stronger the catalytic ability.…”
