We presented the recent progress in the application of in situ/operando XAS in the understanding of the redox mechanism of lithium sulfur batteries, which is of great significance for the development of high-performance lithium sulfur batteries.
Significance and Impact
The new insights from the in situ/operando XAS results have offered a real-time characterization capabilities for monitoring the electronic structure evolution of both cathode and anode materials for lithium sulfur batteries.
- The reaction mechanism of sulfur and Li2S electrodes investigated by in situ/operando XAS is presented.
- The confinement of intermediate polysulfides by functional polymer binders is summarized.
- The synergetic effect of electrolyte additive and polysulfides on the formation process of SEI layer is presented.
