Exploring why an accidental discovery may have unlocked the holy grail in battery research: an energy dense, long lasting, and safe battery. Lithium sulfur batteries may be the holy grail of energy storage. Besides fueling electric vehicles (EVs) adoption, they could turbocharge the integration of renewable energy into our electric grid. However, a technical fault has been holding back their economic feasibility…until now. Could this lithium sulfur discovery from Drexel University make it the future of battery storage?
