Printable Thin Film Batteries with new material systems - Subproject: Printing technology exploration of primary batteries
|Funding source:||BMBF Verbundprojekt
|Duration:||01.04.2011 - 31.03.2015|
|Abstract:||The objective of the project is to explore flexible primary and secondary thin film batteries. These batteries do not have a metal encapsulation and are therefore very thin and flexible. In contrast, regular batteries which are manufactured with pick-and-place technologies are rigid and thick. The used materials for the thin film batteries are comparable with the material of regular batteries but the manufacturing process needs to be adapted to the specific application and the materials need to be optimized in order to be environmental friendly.
For the manufacturing process of the flexible thin film batteries, printing technologies are employed since they are highly productive and cost-efficient. The different chemical layers are printed in one machine one after the other and so the different processing stations of pick-and-place are no longer necessary.
Until now, only standardized batteries are available for any kind of application but the advantage of the thin film batteries is that they are shape-variable and could be directly integrated into the application. This integration allows for example to provide labels with energy efficient electrical display elements which therefore do not need to be equipped with bulky button cells from which only a small amount of the stored energy is used for the application. The added value for customers would be that they can apply innovative information elements and moreover, product authenticity features.
The emerging market of "printed electronics" requires a flexible and performance adapted electrical energy source. This flexible energy source can be the printed thin film battery which enables to realize flexible products which are currently provisionally driven with button cells.
