Abstract
An electrochemical device including a stack of solid thin layers formed on a substrate, the stack successively including, a first current collector covering a part of the substrate, first electrode defining a pattern having bottom surface, top surface and side walls, the bottom surface of the pattern covering at least part of the first current collector, electrolyte layer configured to cover at least the top surface and at least part of the side walls of the pattern of the first electrode, a second electrode totally covering the electrolyte layer, the thickness of the electrolyte layer arranged between the walls of the pattern of first electrode and the second electrode being substantially equal around the pattern to within 20%, a second current collector totally covering the second electrode, the second current collector and the second electrode being electrically insulated from the first current collector and from the first electrode.
