Exploring reaction dynamics in lithium-sulfur batteries by time-resolved operando sulfur K-edge X-ray absorption spectroscopy.

ABSTRACT

A time-resolved operando X-ray absorption spectroscopy experiment was successfully designed to explore the sulfur reaction dynamics in lithium-sulfur (Li-S) batteries. It presents direct real-time experimental evidence for the distinct sulfur dynamics at different discharge rates, deepening the understanding of reaction mechanisms in Li-S batteries.
