Abstract:

Disclosed are electrochemical devices, such as lithium metal batteries using a solid state electrolyte. A means is disclosed to achieve relevant charging rates without short-circuiting a cell of the electrochemical device by limiting the electrode area, positioning the electrode where least defect population exist and controlling the external variables for stable lithium electrodeposition. Also disclosed is a method for visualizing metal propagation from an anode into a solid state electrolyte during cycling of an electrochemical cell comprising the anode and the solid state electrolyte.
