1. A method of forming a battery cell, comprising:
providing for one or more layers between a first electrode structure and a second electrode structure containing an ion material, the one or more layers including an electrolyte precursor layer with a planarized electrical insulating ion conducting layer; and
applying a voltage between the first electrode structure and the second electrode structure to provide ion flow from the second electrode structure to the first electrode structure through the electrolyte precursor layer, form an ion conducting electrolyte from the electrolyte precursor layer during the ion flow, deposit a layer of metal on the first electrode structure to form an anode where the first electrode structure and the one or more thin-film layers form a current collector electrode, and form a cathode from the second electrode structure.
