Spatial ALD from Lab to Fab

In all growth markets, maximum throughput at the lowest possible costs is essential for success!

SALD has developed a unique technology that makes this possible, which is protected by several patents. This technology has been incorporated into a compact machine that can be used for research as well as for small-scale production. It does not matter which material is involved: battery electrode, solar cell, OLED or foil. Moreover, SALD is the only company in the world that has the expertise to subsequently quickly and reliably upscale the Spatial ALD technology to high volume production.
In Spatial ALD (SALD) precursors are continuously supplied in different locations and kept apart by an inert gas region or zone. Film growth is achieved by exposing the substrate to the locations containing the different precursors. The process is very fast and compatible with fast-throughput techniques such as roll-to-roll (R2R), and is versatile and cheap to scale up. In addition, one of the main assets of SALD is that it can be performed at ambient pressure and even in the open air, while not compromising the deposition rate.

New era of web tension PROFILE monitoring in coating lines

Measurement of tension in web materials is well known since decades. The development focus was on precision of the loadcells and amplifiers with higher resolution, shorter cycle times and communication interfaces. State of the art is one loadcell on each side of an idler roller. Evaluation in the electronic unit can be sum / average of both signals or also independent evaluation of left/right signals. This allows an accurate measurement of the (overall) tension in a web. But it does not give any information about the lateral distribution of tension across the web. Although very often a web material does not have the same properties across the web (humidity in the material, thickness = gauge etc).

With production processes requiring tighter and tighter tolerances this information is no longer sufficient. Especially with wider webs one needs to ensure that the material properties are the same all over the web width. This can be measured by a multitude of loadcells across the web. With such a measurement (monitoring) device it is possible to do a real-time analysis of the tension profile / distribution across the web. You can also detect loose edges, one-side tension concentration, repeating patterns over time / length. This measurement is the base for improving previous (upstream) processes and in addition it allows the qualification of different rolls according to their consistency of tension across the web. The operator can influence the process based on the measurements (web guiding, banana rollers etc) and also document the results through standard interfaces. This new system, the FMS-segFORCE introduces a new era of web tension profile monitoring.

Flexo graphic printing for technology markets and converting

Flexibility and challenging solutions are required for coating lines. Printing processes are often integrated in converting lines to give added value to the machine. Logo print in silicone release liner coating lines is a standard solution and even pattern silicone application is realized within fast running coating lines. And flexo printing processes are used in challenging applications too such as design application for battery electrodes and even printed electronics applications. KROENERT will give with the presentation an overview about flexo graphic printing technology and application samples for high-speed converting machines but also for high-end solutions like printed electronics.

Slot dies originally have been invented for uniform, endless, full area coatings. Their dedicated advantages to be a premetered closed system are more and more requested as well for intermittent coatings, e.g. in the battery industry. The main problem of intermittent slot die coating, namely the successive fast start and stop of the coating process, has meanwhile been solved quite satisfyingly for rather high viscous slurries. For low viscous liquids there are still problems to achieve well defined coating edges. A new method is presented, still being in development, to overcome such issues.

High speed inkjet printing – A system integration perspective

In recent years, several markets (e.g. coating) are adopting integrated digital technologies to print functional layer which is pushing Inkjet technology to achieve high speed (> 100 meter/min) with drop placement accuracies (+/- 10 micrometers). This induces challenges (amongst others) with respect to vibrations of mechanical modules (print bar), high flow rate in the ink delivery system and power supplies requirements for fast print head activation. In this presentation, we elaborate the challenges along with the its effects and propose a solution space from a system integration perspective to achieve high speed printing with desired accuracy.

TNO-Holst Centre, High Tech Campus 31, 5656 AE Eindhoven, The Netherlands

The key challenges in next-generation all-solid-state Li-ion battery technology are related to the energy and power densities required, fast charging constraints, battery lifetime, while keeping the cost low by high-volume manufacturing. A combination of high energy density anodes such as Si or Li, and Ni- or Li- rich cathodes 1,2 is necessary to achieve high energy densities.

However, many of such high-potential redox-chemistries lead to serious safety issues and degradation during cycling due to either oxidative or reductive instabilities 3, especially occurring at the electrode-electrolyte interface 4. The solution is to optimize the interfaces with chemically and mechanically-stable Li-ion conductive passivation layers depending on the Li-ion battery chemistry in order to mitigate the non-compatibility of the individual cell components. The interfacial stabilization layers can be formed either in-situ using electrolyte additives or ex-situ via chemical and physical methods. One option here is offered by atomic layer deposition (ALD) which is the preferred technique to achieve superior quality and 3D-conformal coatings with atomic-scale thickness precision.

However, conventional vacuum-based ALD is not compatible with the mainstay high-throughput roll-to-roll battery electrode production. Here, the large-area atmospheric-pressure spatial-ALD (s-ALD) technology -as established by TNO-Holst Centre several years- ago can offer prime solutions for various applications including thin-film batteries 5. A wide range of materials like metal oxides, nitrides, sulfides, and hybrid organic-inorganic materials are possible using s-ALD. In this talk, we will introduce the R2R upscalable spatial-ALD technology and its potential applications for batteries. Furthermore, we will discuss the latest results on our s-ALD grown thin film LiPON electrolyte having a Li-ion conductivity >10-7 S/cm, low electronic conductivity (<10-12 S/cm). Such electrolyte is also relevant for the development of protection layers in liquid and polymer electrolyte-based Li-ion batteries, as well as for enabling thin-film planar and 3D solid-state batteries with ultra-thin electrolyte layers.

Nanocellulose as sustainable packaging substrates

The development of sustainable packaging materials with lower environmental impact is an urgent need of our society. Although significant improvements have been made, it is still challenging to achieve a trade-off between eco-friendliness and both, low production costs and sufficient packaging performance. One promising material that might succeed in creating this balance is nanocellulose - a nature-derived and renewable nanomaterial that shows excellent mechanical and barrier properties. However, using nanocellulose it is quite challenging to obtain homogeneous defect free layers. The unexceptionally high viscosity and thixotropic behaviour of nanocellulose based solutions makes it difficult to deposit this material with standard coating methods. Furthermore, another crucial aspect is the high solvent content of the typical nanocellulose solution (between 99 and 95%), causing very high demands for the drying process. 

We will present our results regarding process development for this demanding material. Using innovative drying technology and optimized coating methods we were able to implement the fabrication of nanocellulose coated paperboard at pilot scale.

Printed electronics for wearable applications

This presentation will explain the work performed at Holst Centre in the field of printed electronics for wearable applications. Using screen printing of stretchable pastes onto stretchable substrates, prototypes for medical and garment applications are being developed. For this, a good insight in material performance is needed, ranging from stretchability of the paste and substrate to e.g. performance of the electrodes to measure heartbeat and ECG signals. Together with our partners and customers, we work together to further improve these mat gain more insight in current materials and develop new applications.
