Electrochemical cell and method of manufacturing

Abstract

An electrochemical cell comprising a lithium metal negative electrode layer physically and chemically bonded to a surface of a negative electrode current collector via an intermediate metal chalcogenide layer. The intermediate metal chalcogenide layer may comprise a metal oxide, a metal sulfide, a metal selenide, or a combination thereof. The intermediate metal chalcogenide layer may be formed on the surface of the negative electrode current collector by exposing the surface to a chalcogen in gas phase. Then, the lithium metal negative electrode layer may be formed on the surface of the negative electrode current collector over the intermediate metal chalcogenide layer by contacting at least a portion of the metal chalcogenide layer with a source of lithium such that the lithium actively wets the metal chalcogenide layer and forms a conformal lithium metal layer on the surface of the negative electrode current collector over the metal chalcogenide layer.
