Template-synthesis of a poly(ionic liquid)-derived Fe_1-x S/nitrogen-doped porous carbon membrane and its electrode application in lithium-sulfur batteries.

ABSTRACT: This study deals with the facile synthesis of Fe_1-x S nanoparticle-containing nitrogen-doped porous carbon membranes (denoted as Fe_1-x S/N-PCMs) via vacuum carbonization of hybrid porous poly(ionic liquid) (PIL) membranes, and their successful use as a sulfur host material to mitigate the shuttle effect in lithium-sulfur (Li-S) batteries. The hybrid porous PIL membranes as the sacrificial template were prepared via ionic crosslinking of a cationic PIL with base-neutralized 1,1'-ferrocenedicarboxylic acid, so that the iron source was molecularly incorporated into the template. The carbonization process was investigated in detail at different temperatures, and the chemical and porous structures of the carbon products were comprehensively anal
