Speaker: Denis Pasero | Company: Ilika | Date: 9-10 Feb 2022 | Full Presentation Solid State Batteries are expected to outperform incumbent liquid-based battery technologies thanks to potential safety and performance advantages. SSBs have the potential to improve and even enable new application over a wide Wh-level range: from micro-batteries powering Augmented Reality smart contact lenses and perpetual Internet of Things sensors; to pouch cells providing safer and lighter power to cordless domestic devices and longer range to electric vehicles and new aerospace applications. Yet, after a few decades of R&D, the commercialisation of small SSB is only recent and that our larger format pouch cells still around the corner. This presentation will compare and contrast the various challenges and choices of chemistries, processes and engineering solutions necessary for the development of mWh level micro batteries to the full commercialisation of SSB modules at GWh level.

A research team led by Japan’s National Institute for Materials Science (NIMS) has developed a new conductive ink for use in printed electronics with significantly improved resistance to oxidation. After the ink is printed, it self-organizes into a conductive pattern with a copper core–nickel shell nanostructure. The researchers say that use of this cheaper, more stable ink may help popularise printed electronics. Silver nanoparticle inks are currently the most commonly used in printed electronics. However, these inks are expensive and poorly compatible with soldering. Copper nanoparticle inks have been considered a viable, cheaper alternative but are extremely susceptible to oxidation, making them unsuitable for use in printed electronics. Development of more stable and economical inks was therefore required. The NIMS researchers focused on inks composed of complexes of organic amine ligands with a central metallic ion because they are stable in the air. The team subsequently discovered that inks containing a mixture of different metallic complexes are capable of converting into different types of printed metallic patterns, including multilayered core-shell nanostructures and alloys, depending on the ink’s composition and other conditions. Based on these findings, the team developed an ink composed of a mixture of copper and nickel complexes able to self-organize into a copper core–nickel shell nanostructure. Because its outer nickel layer is resistant to oxidation, th...

Speaker: Carolyn Ellinger | Company: Eastman Kodak Company| Date: 10-11 March 2021 | Full Presentation Print technologies are being used today in the manufacture of consumer products, including flexible electronics and optics. There are multiple available printing technologies that offer a range of addressable resolutions and obtainable throughputs (i.e. print speed). Resolution and speed are only part of the story, one also needs to understand the latitude for useable inks and the volume of those inks that can be deposited at speed in a single-pass process with good pattern fidelity. EKTAFLEX functional printing solutions enable flexographic processes to achieve sub-10-micron on-substrate features. This talk will focus on the advantages of high-resolution flexography, and how these small features sizes can be used to create advantaged products. Included will be a review of both the innate capabilities of flexography and application specific benefits over other print technologies, such as drop-on-demand inkjet. Examples of both additive and subtractive processing via high resolution flexography will be discussed. Real case studies will be presented, including Kodak’s own additive, roll-to-roll (R2R) manufacturing process for copper micro-wire patterns on flexible substrates used for transparent RF devices, such as antennas and EMI shields. In addition, success cases from partners’ use of Kodak’s EKTAFLEX plates for functional printing will also be shared – illustrating not ju...

Printed electronics technology is evolving. A development direction is ultrafine line printing, increasingly allowing the technology to encroach into the realm of photolithography. In this article, we discuss analogue direct as well as hybrid printing technologies, bringing printed electronics into the few micron and sub-micron feature size range. This is an important development, taking printed electronics closer to electronic applications. In a subsequent article, we will cover digital printing techniques. This article is based upon recent presentations and discussions at TechBlick events. TechBlick is the home of the global printed electronics industry, providing year-round online and onsite world-class conferences, masterclasses, and industry updates. Join TechBlick on an annual or monthly annual pass to connect with the global printed electronics community (www.TechBlick.com). Our next Printed Electronics event will be an online Innovations Festival taking place on 24 June 2022. This article begins with screen printing, as it is the powerhouse of the industry. Without the exception of displays, most printed electronics applications rely upon this technology. Today, many regularly print ca. 50µm linewidths in production on flexible substrates. However, the state-of-the-art is already pushing below this limit. Here, I show two interesting examples. The right image is from Fraunhofer ISE (2019), showing how they could screen print 19µm wide lines on silicon solar cells to a...
