Abstract
A negative lithium-containing electrode for an electrochemical cell is provided, along with methods of making such a negative lithium-containing electrode. The method includes depositing a first precursor and a second precursor in a vapor deposition process onto one or more surface regions of a negative electrode material comprising lithium. The first precursor and the second precursor react to form an inorganic-organic composite surface coating on the one or more surface regions. The first precursor comprises an organic mercapto-containing silane and the second precursor comprises an inorganic silane.
