Julia Greer: From ion to atom to dendrite

Markus Buehler of the Massachusetts Institute of Technology and editor of the Impact section of MRS Bulletin interviews Julia Greer, director of the Kavli Nanoscience Institute at the California Institute of Technology about her research on the formation and nanomechanical behavior of electrodeposited lithium for Li-ion batteries. Greer’s group developed an in situ experimental methodology that allows them to electrochemically charge small-scale battery cells and to observe, in real-time, the formation of Li dendrites and to probe their mechanical response. Their work is published in MRS Bulletin (doi:10.1557/mrs.2020.148)
