Bazant explains that most previous research on the use of lithium metal anodes has been carried out at low current levels or low battery capacities, and because of that the second type of growth mechanism had not been reliably observed. The MIT team carried out tests at higher current levels that clearly revealed the two distinct types of growth.
He says that the findings were made possible by his team’s development of an innovative laboratory setup, a glass capillary cell, that “allows you to see the growth, and you can see where there is this transition from one kind of growth to the other.” Previous research had mostly relied on electrical measurements to infer what was taking place physically inside the battery, but seeing it in action made the differences very clear. The slow, mossy growth proceeds for a while, and then at a certain level of current, “all of a sudden, this little finger [of lithium] snaps out. It allows you to see exactly when the dendrites begin.”
The new findings will now provide battery researchers with a better understanding of the underlying scientific principles, and show “what are the limitations on rates and capacity that are achievable,” Bazant says.
