Battery arrays, constructions and method
Disclosed is a stacked array of a plurality of thin film batteries electrically connected in a staggered configuration, where the side edges of the array preferably generally conform to an interior surface of an electronic device or component thereof in order to save space. In an embodiment, the stacked array comprises at least one battery having a single surface in contact with a plurality of batteries. In another embodiment, a shaped array of a plurality of thin film batteries electrically are connected together, whereby a plurality of batteries are arranged in a single layer on a non-rectangular substrate adjacent to one another generally in the shape of the surface of the substrate. Additionally, a thin film battery is described having at least one via through the substrate and at least one other via through an insulation layer to provide electronic connection to the battery cell.
1. A method of providing power to an electronic device using a plurality of thin film batteries including:
stacking the plurality of thin film batteries in a staggered configuration to form a stacked array having outermost points of side edges on one side of the stacked array;
placing the stacked array in the electronic device so that the outermost points of side edges on one side of the stacked array generally conform to an interior surface of the electronic device; and
before or after placing the stacked array in the electronic device, electrically connecting the plurality of thin film batteries, wherein the batteries are of uniform size and shape.
2. The method of claim 1 wherein the interior surface is a planar surface.
3. The method of claim 1 wherein the interior surface is a curved surface.
4. The method of claim 1 , wherein the plurality of thin film batteries are electrically connected before placing the stacked array in the electronic device.
5. The method of claim 1 , wherein the plurality of thin film batteries are electrically connected after placing the stacked array in the electronic device.
6. The method of claim 1 , wherein the stacked array conforms to at least two adjacent inner surfaces of the interior of a compartment of the batteries.
7. The method of claim 1 , wherein the plurality of thin film batteries have a top perspective view shape other than square or rectangular.
8. The method of claim 1 , wherein the plurality of thin film batteries have a top perspective view shape selected from crescents and semi-circles.
9. The method of claim 1 , wherein the plurality of thin film batteries have a top perspective view shape selected from triangles, and trapezoids.
10. The method of claim 1 , wherein the plurality of thin film batteries are cylindrical thin film batteries.
