Spatial Atomic Layer Deposition (ALD) for batteries, fuel cells, packaging and solar

Can you improve the world with a very thin layer, the size of one atom?
Yes we can, we can improve the world!

Imagine the world's highest-quality nanotechnology finding its way into everyday applications.

The lifespan of batteries is increasing, charging becomes faster, and electrolysers for hydrogen can be produced much cheaper and greener. Improving these products has a major impact on the energy transition. 

Thanks to this nano technology; -Spatial Atomic Layer Deposition-, you literally grow layers at atomic level, increasing the efficiency of solar cells, for example, by as much as 10%. 

This nano technology has been successfully applied in the high-quality semiconductor industry since the eighties. We want it to find its way into everyday applications, on a gigantic scale. And we, SALD, a machine and system builder from Eindhoven, have tackled this problem. 

We have embraced the technology and are the first in the world to develop machines and systems that make this accessible for much larger surfaces, and at a low cost.

Our patented machines and systems have been implemented at leading institutes and companies around the world. There the benefits of our technology are recognized and publicized.

We conduct feasibility studies with global technology leaders to validate our technology and later integrate it into their production lines.

We are ready for the large-scale deployment of our production machines, which will serve solar cells, packaging, medicines, batteries, and the automotive industry. This step will lead to significant sales growth, both through machine sales and the supply of raw materials. 

In this way, together with our customers, we contribute to making our planet more sustainable.

OPV development to the Giga Fab (Flex2Energy)

In the domain of renewable energy, the journey from OPV development to the realization of a Giga Fab is an exciting endeavor that holds the promise of revolutionizing the energy landscape.  

Organic Photovoltaics (OPVs) play a pivotal role in this transition. OET, a pioneering company in the field, is leading the charge in OPV technology, representing a significant leap forward from traditional manufacturing practices. 

At the heart of this presentation lies the Flex2Energy project. The project's primary goal is to take OPV technology to the industrial level. It aims to establish an Automated Roll-to-Roll (R2R) Manufacturing Line for OPVs, featuring R2R Printing & Automated Assembly Machines. Robust in-line metrologies for quality control, complemented by industry 4.0 concepts, form the core of this endeavor, ensuring that the path from OPV development to the Giga Fab is not only transformative but also sustainable and widely embraced.

MEA production equipment

Werner will do a short introduction of the company and their traditional products, markets and technologies, to show the starting point of this new venture. Optima will explain the areas of the technology transfer and were these technologies are applied to in the fuel cell manufacturing process. Challenges of the fuel cell production i.e. tolerances, materials etc. will be highlighted and suitable solutions already applied in the packaging industry will be shown.

It will be explain for which of the production steps and for which speeds Optima can provide suitable machines.

Quality control systems inline for fuel cells

Dr. Schenk has been manufacturing inspection systems with a focus on web products since 1985. For the inspection of fuel cells, 3 inspection tasks can be performed in one system: Detect local defects such as pinholes and scratches with positional accuracy, monitor measurement tasks such as coating widths and material proberties such as roughness and homogeneity. All this is ensured by the in-house development and production of high-performance smart line scan cameras, LEDs and software. 

Fuelcell2Print: Digital material deposition for catalyst coated membrane production

Printing as a „non-all-over” coating process typically comes into play when designs are complex, like for multimaterial „coatings” or when material waste by i.e. overspray is to be avoided.

When substrates are delicate, contactprinting is often not the preferred process because it is associated with pressure. Pressure on the substrate itself or on a previously applied potentially vulnerable layer.

Digital printing as a printing-form-free process can be contactless- like a coating process- but bear in itself the precision of contact printing while providing complete design freedom, wet on wet print capability and a digital workflow.

Add inks with a wide viscosity range and no restriction on particle size, here is the perfect description of the Heliosonic printing technology.
We enable material savings through precise start-stop printing without compromising on printing speed, gas flow modifications through controlled porosity and channel design, the introduction of printed sensors on a per cell level and last but not least the individual digital coding of every ccm unit.

Coating Control – intelligent networked edge alignment for renewable energy

The role of Slitting Technology for reaching Net Zero by 2025 – challenges & chances

Due to long term experience in the field of industrial slitting, many production challenges regarding the handling of coated and non-coated non-ferrous metal foils can be addressed with existing technology. New requirements, resulting from the industry´s high quality standards and needed process stability bring up new tasks.

These need to be addressed with latest technology and innovations. It is a must for non-Asian suppliers to adapt to the markets requirements in order to be competitive and to increase market share while reaching for Net Zero targets.

Dr.-Ing. Simon Britten

High efficient diode lasers for drying applications of electrodes and beyond

Major challenges in coating processes today are given by the subsequent drying process. Conventional hot air convection approaches result in high footprint / very long oven systems up to 100m and are due to the low energy efficiency responsible for almost 30% of the energy consumption in e.g. battery production process.

In this talk we present a new laser drying solution, where all energy is focused by rectangular laser spots directly into the coating material, without heating of the surroundings. This cold energy transfer allows a highly efficient heat creation inside the material. In combination with remote optics with increased working distance, new possibilities in quality control by thermography are enabled. As there is practically no intensity limitation by laser, also high temperature processes >1000°C can be realized.

Inline quality control system for organic electronics

In-line characterization of compositional, electronic and structural properties of advanced thin film solar cells

C.Defranoux, F.Korsos, T.Brigancz

Semilab Co. Ltd.,  Prielle Kornelia 4/A. str., H-1117 Budapest, Hungary

As the result of continuous improvement in the performance of thin film solar cells, especially organic, perovskites and tandem cells, they are now ready for high-volume production. For this, the real challenge is to stabilize the layer quality and ensure high yield. Thus, fast, stable, well established and accurate inline characterization methods are required for the proper production control.

This work consists of the review of the in-line compatible optical and electro-optical measurement techniques already established or being in development phase to access structural, compositional and electrical performance parameters during the production. Limitations, challenges, and the potential benefit of their in-line usage are discussed in detail via presenting recent results on novel thin-film solar cell layers.

Electrical properties of the various TCO structures, must be checked and control in line using the application of the well-known radio-frequency eddy-current method to acquire the sheet resistance of TCO layers on insulator substrate or newly developed a surface-photovoltage based method which enables the characterization of TCO layers deposited onto the active layers.

Results from inline spectroscopic ellipsometry measurement are presented. It proves to provide rapid (<100ms / data point) and reliable multi-layer characterization of thickness and refractive index of solar cell layers either on solid or flexible substrates in roll-to-roll production. New optical set up with smaller spot and real time focus are also presented.

We report on the ongoing results and concepts of the application of the Imaging photoluminescence (IPL) phenomenon for the process control in thin-film solar cell production. Example on PL emission observed in perovskite layers and cells in a peak around the target bandgap will be shown in addition to the inline IPL obtained on Organic PV cells in the frame work of the Real nano EU project.

The high emission intensity promises the in-line application of spectroscopic PL, PL imaging for production control and especially defect analysis. The results enable to conclude that beyond the uniformity and the compositional information, the PL and IPL measurements are applicable to rate the electrical performance and the quality of organic and perovskite solar cell structures.

Process optimization enabled by Digital Twins

While the term Industry 4.0 has been around for more than 10 years already, all too often the hoped-for promises never became reality.

Recognizing that comprehensive data lakes are an indispensable prerequisite for process optimization, Coatema has adopted  the ARENDAR digitalization solution as an optional feature for all product lines. This innovative and powerful connectivity module enables complete, standardized and secure access not only to the machine information itself, but to all relevant process data.

Based on an intelligent IoT gateway that integrates seamlessly into virtually any store floor, the ARENDAR solution offers a range of features that allows Coatema's customers to realize the full potential of digital twins.

The ARENDAR solution enables Coatema machines to be connected to adjacent processes on the store floor and data to be transferred securely both to the local IT infrastructure and to cloud systems as needed.

By putting ALL data (machine information, process conditions, environmental sensors) into a common context, data is transformed into valuable information, creating the holistic data sets needed for more advanced analytics.

The presentation will explain the key functionalities and highlight the numerous possibilities using examples from different industries.

In-line Monitoring of the Platinum Content for Fuel Cells Membranes with XRF

Platinum and PGMs are essential for the proper functioning of fuel cells. The Pt content of catalyst layers can be easily monitored in-line using X-ray fluorescence spectroscopy. In this way, the quality of the catalyst layer can be ensured, and precious metal consumption and costs can be optimised.

Intelligent automation-cloud communication enables evolving production services

Here we discuss the option where the production system has open communication interfaces.
Each individual process application is managed from cloud, while the process objects are executing in real-time at the physical process. For process integrator this offers a nice distribution of responsibilities. For process application owners this opens the ability to manage/develop fleets of products without visiting sites.

The process owner will gain additional benefits for production specific data. This data opens opportunities for a new data processing service business.

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.

HyFab PEM fuel cell MEA production research at ISE

Today’s PEM fuel cell catalyst production research addresses the challenges of upscaling and optimizing the fabrication process, which includes increasing throughput rates while maintaining quality demands. Within the project HyFab we are addressing these challenges and establish production related competences in the field of hydrogen technologies together with the Center for Solar Energy and Hydrogen Research Baden-Württemberg (ZSW). At Fraunhofer ISE, we are investigating the whole production line coming from the catalyst ink, applying flatbed screen printing and the transfer process to manufacture membrane electrode assemblies. Different ex-situ quality control measurements are shown to evaluate correlations of coated catalyst layer and catalyst ink properties. Finally, the fabricated fuel cells are characterized electrochemically during operation.

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.
