Bottom row: top view and cross sections of deposited lithium at 350 kPa, or 3.5 atmospheres
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...
