In previous work, Sayavong and his colleagues discovered that the SEI matrix begins to dissolve when the battery is idle. Based on that finding, the Stanford team decided to see what would happen if the battery was allowed to rest while discharged.
A new study presents possible solutions to a problem known to cause degradation and failure in lithium-metal batteries. | alengo/iStock Next-generation electric vehicles could run on lithium metal batteries that go 500 to 700 miles on a single charge, twice the range of conventional lithium-ion batteries in EVs today.
“It surrounds isolated pieces of lithium metal stripped from the anode and prevents them from participating in any electrochemical reactions. For that reason, we consider isolated lithium dead.” Repeated charging and discharging results in the build-up of additional dead lithium, causing the battery to rapidly lose capacity.
Lithium metal batteries could double the range of electric vehicles, but current batteries degrade quickly during operation. Stanford researchers have discovered that you can improve the battery’s cycle life simply by letting it rest for several hours in the discharged state.
In a lithium metal battery, the graphite anode is replaced with electroplated lithium metal, which enables it to store twice the energy of a lithium-ion battery in the same amount of space. The lithium metal anode also weighs less than the graphite anode, which is important for EVs.
“We were looking for the easiest, cheapest, and fastest way to improve lithium metal cycling life,” said study co-lead author Wenbo Zhang, a Stanford PhD student in materials science and engineering. “We discovered that by resting the battery in the discharged state, lost capacity can be recovered and cycle life increased.
