Abstract

A method for production of a thin-film battery includes providing a mount structure, applying of a first unmasked flow of a first electrode material to the mount structure in order to form a first electrode layer, applying a second unmasked flow of a battery material in order to form a battery layer, and applying a third unmasked flow of a second electrode material in order to form a second electrode layer. The applying steps are repeated in order to produce a thin-film battery which consists of a plurality of first electrode layers, a plurality of battery layers, and a plurality of second electrode layers.

First claim

What is claimed is:

1. A method for production of a thin-film battery, comprising:
applying a first unmasked flow of a first electrode material to a mount structure in order to form a first electrode layer on the mount structure;
applying a second unmasked flow of an electrolyte material directly on the surface of the first electrode layer in order to form a battery layer on the first electrode layer;
applying a third unmasked flow of a second electrode material directly on the surface of the battery layer in order to form a second electrode layer on the battery layer;
repeating the step of applying a second unmasked flow of an electrolyte material directly on the surface of the second electrode layer to form a battery layer on the second electrode layer;
repeating the applying steps commencing with applying an unmasked flow of the first electrode material directly on the surface of the battery layer formed on the second electrode layer and ending with the step of applying a third unmasked flow of a second electrode material in order to produce a thin-film battery which includes a plurality of first electrode layers, a plurality of battery layers and a plurality of second electrode layers; and
thereafter structuring the thin-film battery.

2. The method according to claim 1 , further comprising:
applying a fourth unmasked flow of an insulating material in order to form an insulating layer before applying the first unmasked flow to the mount structure and/or after applying last layer of the second electrode layer.

3. The method according to claim 1 , wherein the first and/or the second electrode material is applied such that the first and/or the second electrode layer have/has a porous structure.

4. The method according to claim 1 , further comprising:
exposing end areas of the first electrode layers and/or of end areas of the second electrode layers; and
making contact between the end areas of the first electrode layers and/or the end areas of the second electrode layers.

5. The method according to claim 1 , wherein the mount structure has a base surface with a first barrier and a second barrier, which is arranged opposite the first barrier, the first unmasked flow is applied obliquely over the first barrier to the base surface, and the third unmasked flow is applied obliquely over the second barrier to the base surface.

6. The method according to claim 1 , wherein the second unmasked flow is applied at right angles to the mount structure.
