Study of Polysulfide Speciation in Lithium Sulfur Batteries using in situ Confocal Raman Microscopy: Introduction

McBrayer, Josefine D.

A transition to sustainable energy is among society’s greatest challenges. With this change, the development of more efficient, safe, and cost-effective batteries is also necessary. Batteries are becoming ever more integral to today’s technology rich world. 3 Intermittent power sources, such as wind and solar, require storage devices to deliver a consistent energy supply. More ecofriendly, electric vehicles, have limited travel distances due to low energy density batteries. Phones and other personal electronics are also reliant on battery performance. An encouraging improvement in specific energy from current, lithium (Li) ion batteries, which are already nearing the bounds of their performance potential, are lithium sulfur (Li-S) batteries.
