Atomic Structure of Electrochemically Deposited Lithium Metal and Its Solid Electrolyte Interphases Revealed by Cryo–electron Microscopy

Lithium metal is the most attractive anode materials rechargeable batteries due to its low electrode potential and high theoretical specific capacity compared with other present electrode materials. However, the aggressive dendritic growth of Li metal during cycling makes it too dangerous for practical use. To address this critical issue, we need not only understanding on the macroscopic but also on the microscopic, nanoscopic and atomistic features to probe more fundamental aspects of dendritic growth process. However, current understanding is limited to ensemble studies using low resolution TEM due to both Li metal and the organic liquid electrolyte are unstable under room temperature and electron beam. To overcome these challenges, cryo-transmission electron microscopy (TEM) techniques used in structural biology has been used in battery studies [1-4].
