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 […]

Queen Mary University of London researchers have discovered how a pinch of salt can be used to drastically improve the performance of lithium ion batteries. They added salt to the inside of a supermolecular sponge and then baked it at a high temperature transforming the sponge into a carbon-based structure. Surprisingly, the salt reacted with […]

Lawrence Berkeley National Lab scientists have discovered a surprising set of chemical reactions involving magnesium that degrade battery performance even before the battery can be charged up. The findings could steer the design of next generation batteries. Rechargeable batteries based on magnesium, rather than lithium, have the potential to extend electric vehicle range by packing […]
