PIMs May Be the Cup of Choice for Lithium-Sulfur Batteries

Membranes based on PIMs feature subnanometer-sized pores that allow smaller ions such as LiTFSI to pass through while blocking larger polysulfide ions (Li2Sx). This selectivity prevents unwanted crossovers that reduce battery lifetimes and performance.

Renewable sources of energy including solar and wind are fast gaining ground on fossil fuels, in part because of their sustainability and…
