The higher pressure causes the lithium particles to deposit in neatly stacked columns, which increases the volume of lithium deposited and prevents porosity.

A team of materials scientists and chemists has determined the proper stack pressure that lithium metal batteries, or LMBs, need to be subjected to during battery operation in order to produce optimal performance.

The team, which includes researchers from the University of California San Diego, Michigan State University, Idaho National Laboratory and the General Motors Research and Development Center, presents their findings in the...

A new lithium-based electrolyte invented by Stanford University scientists could pave the way for the next generation of battery-powered electric vehicles.

In a study published June 22 in Nature Energy, Stanford researchers demonstrate how their novel electrolyte design boosts the performance of lithium metal batteries, a promising technology for powering electric vehicles, laptops and other devices.

“Most electric cars run on lithium-ion batteries, which are rapidly approaching their theoretical limit on energy density,” said study co-author Yi Cui, professor of materials science and engineering and of photon science at the SLAC National Accelerator Laboratory...
