Abstract
Provided herein are battery cells comprising artificial solid-electrolyte interphase (SEI) layers used as protective coatings on electrodes. The SEI layers are produced by liquid-phase deposition (LDP). The battery cell may comprise an anode, a cathode, an electrolyte disposed between the anode and the cathode, a polymer separator disposed between the anode and the cathode, and a casing containing the anode, the cathode, the electrolyte, and the polymer separator, wherein at least one or the anode or cathode comprises an SEI layer produced by an LDP method.
