Abstract
Making a rechargeable Lithium energy storage device begins by forming one or more trenches in a solid silicon substrate. One or more region interface precursors are deposited in the trench followed by one or more anode materials, one or more solid polymer electrolytes (SPE), and one or more cathode materials. Electrically cycling transforms the battery structures prior to full operation of the battery. Some, or all, of the process steps can be performed while the materials are within the trench, i.e. in-situ.
