SEM images showing effect of pressure on lithium deposits in batteries

Caption

Top row: top view and cross sections of deposited lithium at 70 kilo-Pascal or kPa (less than one atmosphere) 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.
