Central Challenges When up Scaling the Manufacturing of Thin-Film Battery Applications
Abstract:In recent years the field of large-area, organic and printed electronics has demonstrated various applications of functional devices. For most of the applications, a reliable supply with electric energy tailored with respect to functional devices and applications is a mandatory, making thin-film battery a challenging area of research. Among a variety of manufacturing concepts printing technologies and their established workflow provide interesting opportunities to fully integrate the battery in a product by customizing its size and shape regarding the device to be driven by that battery. Hence, these printed electronics applications will contribute a new momentum in the packaging market.
Out of the well-known battery concepts for thin-film batteries, the well understood zinc manganese dioxide battery system is very promising due to its simplicity and its environmental sustainability. Therefore it has been chosen to study appropriate fabrication opportunities based on printing technologies. In this paper, we report on the development of a process workflow and, the setup of a pilot manufacturing line, taking into account the requirements to adapt the energy content, the size and the shape to the powered product. The overall manufacturing procedure is divided into single process steps, following the traditional printing workflow which is used in the printing and media industries consisting of Prepress, Press and Post Press.
The paper maps the advantages of an automated production process and covers the introduction of process documentation, aspects of quality control, cost minimization and the efficiency improvement. A basic concept for an adapted digital workflow comprising the definition of relevant metadata and job ticket content, which is required for further industrial fabrication of thin film batteries, will be presented.

For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
