Claim Text:
1. A method for preparing an electrode layer of interconnected hollow nanostructures containing a high capacity electrochemically active material, the method comprising: receiving a template comprising template structures; forming a nanoscale coating of the high capacity material around the template structures; and at least partially removing and/or shrinking the template to form the electrode layer of the interconnected hollow nanostructures comprising the high capacity active material, wherein forming the nanoscale coating of the high capacity materials around the template comprises: an initial deposition stage performed at initial process conditions, wherein no substantial shape distortions of the template occur during the initial deposition stage; and a bulk deposition stage performed at bulk process conditions that are different from the initial process conditions and configured to provide a higher deposition rate of the nanoscale coating during the bulk deposition stage.
