Researchers uncover an unexpected route to better lithium-sulfur batteries by visualizing reactions at the atomic scale. The journey from a laboratory discovery to real-world application can be extensive and fraught with challenges. Take the lithium-sulfur battery, for instance. While it boasts sig
. Over the past decade, they have made several pivotal discoveries related to lithium-sulfur batteries. Their latest revelation, published in Nature, unlocks a previously unknown reaction mechanism that addresses a major shortcoming — the batteries’ very short lifetimes.Our team’s efforts could bring the U.S. one large step closer to a greener and more sustainable transportation landscape.”
Despite these benefits, transitioning from laboratory success to commercial viability has proven elusive. Laboratory cells have shown promising results, but when scaled up to commercial size, their performance rapidly declines with repeated charge and discharge. In unlocking this black box around the reaction mechanism, the scientists employed cutting-edge characterization techniques. Analyses of the catalyst’s structure with the intense synchrotron X-ray beams at beamlineOffice of Science user facility, revealed that it plays a critical role in the reaction pathway. The catalyst structure affects the shape and composition of the final product upon discharge, as well as the intermediate products.
With this the team’s latest breakthrough, the future of lithium-sulfur batteries appears brighter, offering a more sustainable and eco-friendly solution for the transportation industry.
