Experiments at SLAC and Berkeley Lab uproot long-held assumptions and will inform future battery design

19-Sep-2018

Over the past three decades, lithium-ion batteries, rechargeable batteries that move lithium ions back and forth to charge and discharge, have enabled smaller devices that juice up faster and last longer. Now, X-ray experiments at the Department of Energy's SLAC National Accelerator Laboratory ...
