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 […]

Better Charging Rate of Lithium Ion Batteries
December 20, 2017 | 1 Comment
A new insight into battery charging is a technique capable of determining lithium metal plating during lithium ion battery charging that supports development of improved electric vehicles. The new technique developed by researchers at Technische Universität München, Forschungszentrum Jülich, and RWTH Aachen University, published in Elsevier’s Materials Today, provides a unique insight into how the […]

Why Your Lithium Battery Goes Bad
April 27, 2017 | Leave a Comment
An Argonne National Laboratory team of researchers has identified one of the major culprits in capacity fade of high-energy lithium-ion batteries. Scientists refer to a battery becoming old is its diminished performance as “capacity fade,” as the amount of charge a battery can supply decreases with repeated use. Capacity fade is the reason why a […]
