Abstract

Methods of preparing and anode/separator assembly for use in electrochemical cells in which a microporous separator layer, such as a microporous xerogel layer, is coated on a temporary carrier substrate, and an anode active layer, such as lithium metal, is then deposited on the separator layer, prior to removing the temporary carrier substrate from the separator layer. One or more protective coating layers may be coated before or after the coating step of the microporous separator layer and prior to depositing the anode active layer. Additional layers, including an edge insulating layer, an anode current collector layer, an electrode insulating layer, and a cathode current collector layer, may be applied subsequent to the coating step of the microporous separator layer. Also, methods of preparing electrochemical cells utilizing anode/separator assemblies prepared by such methods, and anode/separator assemblies and electrochemical cells prepared by such methods.
