| 摘要 |
The invention relates to a battery comprising an electrically non-conductive substrate (1) on which it is arranged, in addition to at least one cathode (4), one anode (6), and a separator/electrolyte layer (5) in the form of layers or films that are pre-formed from an electrochemically active or activatable material and optionally a polymer matrix and/or other auxiliary substances, in a corresponding sequence on the substrate (1). The layer thickness of each electrode layer is 10 µm. The inventive battery also comprises at least one current diverter (7) and at least one battery contact (2, 2a, 2b) that are respectively in electrical contact with an electrode. Said battery is characterised in that it comprises at least one first covering layer (8, 16, 17, 21) consisting of a first, electrically insulating material that is stable in relation to the used electrolyte and electrode material and has been deposited from the gas phase or in the form of a liquid or viscous paste. Said covering layer forms an encapsulation element with the substrate and optionally at least one other component, by which means the battery is sealed from the surrounding environment, and is provided with at least one recess (11, 18, 19) that is closed by an electroconductive material and is connected to at least one current diverter (7) of the battery. The invention also relates to a plurality of such batteries on the same substrate, and to methods for producing the cited batteries using wafer-level techniques. |
