Argonne National Lab scientists have developed a fluorine containing electrolyte for lithium-ion batteries whose charging performance remains high in frigid regions and seasons. They also determined why it is so effective. The research report has been published in the journal Advanced Energy Materials. ┬áMany owners of electric vehicles worry about how effective their battery will […]

Sandia National Laboratories’ new study tackled a long-held assumption that adding some liquid electrolyte to improve performance would make solid-state batteries unsafe. Instead, the research team found that in many cases solid-state batteries with a little liquid electrolyte were safer than their lithium-ion counterparts. They also found, if the battery were to short-circuit, releasing all […]

Brookhaven National Laboratory scientists have identified the primary cause of failure in a state-of-the-art lithium-metal battery, of interest for long-range electric vehicles: electrolyte depletion. Using high-energy x-rays, they followed the cycling-induced changes at thousands of different points across the battery and mapped the variations in performance. At each point, they used the x-ray data to […]
