Blackstone Resources AG: Artificial Intelligence (AI) validation of 3D printed battery cells and solid-state batteries

Ad hoc announcement in accordance with art. 53 LR

BAAR, Switzerland – (05 October 2021) – Blackstone Resources AG (SWX, symbol BLS, ISIN CH0460027110) is pleased to announce that the production of 3D printed battery cells now also has a valid and solid scientific basis. “This is the result of a complex production simulation that was also carried out with the Bern University of Applied Sciences (BFH) “ explains Serhat Yilmaz, Marketing Director of Blackstone Resources AG. “The validation process involved over 250 process parameters and 90 product parameters to verify this unique production technique against our reference model.”

This proves: printing battery cells using Blackstone’s patented process reduces the material costs of 20 € / kWh thanks to better use of inactive materials (fewer collector sheets and separators). “This result has been verified and confirmed by independent experts on behalf of the funding body Innosuisse “, Yilmaz said. On this basis, Innosuisse has now released another slice of money for the project, which Blackstone will use to create other solid-state battery printing models. The simulation also showed that production costs can be reduced by about 20%.

Cyclical optimization of the production process with artificial intelligence

Along with this validation process, Blackstone Technology has developed an artificial intelligence (AI) system with the Saxon company Symate GmbH, which will be integrated into the production of printed electrodes and battery cells by December 2021. “This will allow mathematical models developed by BFH to be fed for the first time with data from the AI ​​Life system, ”explains Yilmaz. “This allows us to optimize our production processes cyclically and in real time. all relevant parameters can thus be stored in a system, optimized and analyzed using AI predictions.

The particular advantage is that the use of AI makes interactions visible. Very complex and data-intensive 3D printing can thus be controlled reliably even in series production. Blackstone is based on the principle of the digital twin.

Digital Twin for 3D Printed Battery Electrodes

The new Blackstone factory in Döbeln, Saxony, relies on digitization and Industry 4.0. “We want to analytically assess the data volumes accumulated in the ongoing manufacturing process and regulate the process based on this data,” says Holger Gritzka, CEO and Managing Director of Blackstone Technology GmbH in Döbeln. “For this purpose we will use a new cyber-physical production system (CPPS). “The CPPS creates a digital twin for each individual energy cell process based on and with the help of artificial intelligence.” Once enough analyzed data is available, the digital twin can be “trained” to give it a normal individual behavior “, explains Gritzka. This normal behavior is then continuously compared to the current production. In the event of anomalies, the possible causes and correlations are then communicated or corrected automatically via a notification system.

3D printed lithium-ion batteries

The patented technology for three-dimensional battery printing was developed by Blackstone itself. It is suitable for producing liquid electrolyte batteries as well as solid state batteries.

With Blackstone’s special 3D printing technology and data-based technologies, production becomes not only stable, but also very flexible (individual process design is possible regardless of customer-specific framework conditions and geometries) . In addition, the the energy density of new batteries is increased by 20%, while the manufacturing cost is reduced compared to currently widely used lithium-ion battery technologies. At the same time, Blackstone can reduce the amount of investment up to70% with the automated manufacturing of batteries by 3D printing.

“By eliminating long drying lines and toxic solvents, we can sustainably reduce energy consumption in electrode manufacturing,” explains Serhat Yilmaz. “In this way, we have created a valuable basis for the future production of new solid-state or solid-state batteries that will set new standards in terms of energy density, charging speed and safety – while maintaining the moderate costs and environmental impacts. “
