Abstract

Provided are novel multidimensional electrode structures containing high capacity active materials for use in rechargeable electrochemical cells. These structures include main support structures and multiple nanowires attached to the support structures and extending into different directions away from these supports. The active material may be deposited as a layer (uniform or non-uniform) surrounding the nanowires and, in certain embodiments, the main supports and even substrate. The active material layer may be sufficiently thin to prevent pulverization of the layer at given operating conditions. Interconnections between the electrode structures and/or substrate may be provided by overlaps formed during deposition of the active layer. Silicide-based nanowires structures may be formed on the main supports in a fluidized bed reactor by suspending the metal-containing main supports in a silicon-containing process gas. A layer of silicon may be then deposited over these silicide nanowires.
