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.

ASTRABAT final video
ASTRABAT investigated and developed a new all-solid-state Li-ion cell architecture suitable for the use of high-energy electrode materials. Watch the video to learn more about the project's results and get in touch for collaboration.
During these 4 years, ASTRABAT investigated and developed a new all-solid-state Li-ion cell architecture suitable for the use of high-energy electrode materials. The ASTRABAT hybrid electrolyte is based on polymers (ORMOCER® and fluorocarbon polymers) and an inorganic filler and membrane (LLZO). These materials tackle the generation 4a of cells using high voltage cathode materials, based on Nickel Manganese Cobalt Oxide (NMC) such as NMC622 and NMC811, and Si-based anode. The project aimed to assess compatible processes for mass production and to generate a new value chain of all-solid-state batteries, including eco-design, end-of-life and recycling.

Green dream or social nightmare? Cobalt at the crossroads of electric mobility
Child labour, human rights violations, and environmental harm. The rush for cobalt sheds light on the downside of the electric dream. And while researchers are looking for technological alternatives for our electric vehicles’ batteries, NGOs warn of repeating the mistakes of the fossil-fuel industry: “We are at a crossroads. The green transition must go fast but needs to be fair, otherwise, we will look back on this critical time with regret”

Tracking materials for sustainability: the battery passport
Batteries are key drivers of the energy transition, but experts agree: for them to unleash their potential, the entire value chain must be tracked. A dedicated tool, which has just been presented in Davos, records their environmental and social footprint: the battery passport.
