Abstract

Recent developments in the use of polymeric materials as device components in lithium sulfur (Li-S) batteries are reviewed. Li-S batteries have generated tremendous interest as a next generation battery exhibiting charge capacities and energy densities that greatly exceed Li-ion battery technologies. In this Highlight, the first comprehensive review focusing on the use of polymeric materials throughout these devices is provided. The key role polymers play in Li-S technology is presented and organized in terms of the basic components that comprise a Li-S battery: the cathode, separator, electrolyte, and anode. After a straightforward introduction to the construction of a conventional Li-S device and the mechanisms at work during cell operation, the use of polymers as binders, protective coatings, separators, electrolytes, and electroactive materials in Li-S batteries will be reviewed.
