Abstract
Embodiments of the present invention generally relate to lithium-ion batteries, and more specifically, to a system and method for fabricating such batteries using thin-film processes that form three-dimensional structures. In one embodiment, an anodic structure used to form an energy storage device is provided. The anodic structure comprises a flexible conductive substrate, a plurality of conductive microstructures formed on the conductive substrate, comprising a plurality of columnar projections and dendritic structures formed over the plurality of columnar projections and a plurality of tin particles formed on the plurality of conductive microstructures. In another embodiment, the anodic structure further comprises a tin nucleation layer comprising tin particles formed on the flexible conductive substrate between the flexible conductive substrate and the plurality of conductive microstructures.
