Cleaning Lithium to Improve Protective Layer

Tech ID: 23691 / UC Case 2009-511-0


Professor Dunn and colleagues have developed a method to improve the homogeneity of a protective layer placed upon a lithium metal surface. By removing surface impurities from the lithium and applying a uniform protective layer, a more homogenous current distribution can be maintained across the electrode and dendrite formation can be suppressed.
