Resumen

The development of more efficient and competitive batteries is crucial for a complete transition to more sustainable energy models. In this regard, all-solid-state lithium-sulfur batteries, especially those based on lightweight solid-polymer-electrolytes, present several benefits in comparison with conventional lithium-ion batteries. However, the performance of these batteries is not satisfactory yet due to challenges related to lithium/polymer compatibility. This work aims to understand the failure mechanism behind that poor performance, and propose different strategies to overcome those limitations. Those strategies include the use of electrolyte additives, electrolyte fillers, alternative imide salts, and fluorine-free salts.
