Provided are methods of preparing a cathode/separator assembly for use in electrochemical cells in which a microporous separator layer is coated on a temporary carrier substrate and a cathode active layer is then coated or laminated on the separator layer prior to removing the temporary carrier substrate from the separator layer. The microporous separator layer may comprise one or more microporous xerogel layers. Optionally, the cathode/separator assembly may comprise one or more protective coating layers which are in contact with at least one of the microporous xerogel layers, and one of the protective coating layers may be coated on the temporary carrier substrate prior to coating the separator layer. Also, provided are methods of preparing electrochemical cells utilizing cathode/separator assemblies prepared by such methods, and cathode/separator assemblies and electrochemical cells prepared by such methods.
