Dear Reader,

After 4 years, ASTRABAT has come to an end.

Over these years, the ASTRABAT project has been a significant endeavour in the pursuit of electric mobility as the main transport mode in the near future. Throughout the project, extensive research, collaboration and innovation have been employed to address the challenges associated with conventional lithium-ion batteries and pave the way for the widespread adoption of all-solid-state battery technology.

ASTRABAT has made substantial progress in key areas:
-        Advancement of solid-state electrolytes for ASTRABAT cells, with a meticulous focus on enhancing ionic conductivity, electrochemical stability, and thermal/mechanical resilience.
-        Strategic selection of electrode materials critical to elevating the overall performance of cells.
-        Upscaling of materials synthesis processes to attain 1 kg-batch production, coupled with the refinement of cell design through conventional manufacturing techniques.
-        Exploration of additive manufacturing methods, such as ink-jet and screen-printing, with a deliberate effort to strike a balance between printability and electrochemical performance.

For an in-depth exploration of specific technical aspects, we invite you to review the info-packs, available for download on our website. Additionally, our final technical handbook provides a comprehensive analysis of the major breakthroughs achieved during the project.

The resource section on our website contains a compilation of scientific papers published by the project, including the latest publication which delves into the opportunities and challenges associated with the fabrication of a 3D silicon anode using inkjet printing.

For those who may have missed our ASTRABAT final event, the highlights are accessible on our YouTube channel. Also, you can gain interesting insights on the final event by reading our dedicated newsletter.

Finally, you can join us at RTR in Brussels to hear in person about the project's final results.

Thank you for being a valued part of the ASTRABAT community; feel free to contact us for exchanges and collaboration.
