Abstract
An anode for an energy storage device is provided that includes a current collector having an electrically conductive layer, a plurality of lithium storage filamentary structures in contact with the electrically conductive layer. For each lithium storage filamentary structure of the plurality of lithium storage filamentary structures, there is a first supplemental layer overlaying at least a portion of the respective filamentary structure, the first supplemental layer including silicon nitride or a first metal compound. There is further a second supplemental layer overlaying at least a portion of the first supplemental layer, the second supplemental layer having a composition different from the first supplemental layer and comprising silicon nitride or a second metal compound.
