Newsletter #4 / October 2023

The seasons change and autumn shows its beauty wherever you go. In the meantime, SUBLIME is progressing, and a lot of tasks could be completed.  

Deliverables

D3.3 – Report on delivery of 10 kg batches for WP5
… has been submitted. Different sulfide-based electrolytes were evaluated for their electrochemical performance, safety, and scalability. A focus was laid on crystalline sulfide electrolytes exhibiting the argyrodite structure, as their properties can be easily tuned by doping strategies. Conductivities well beyond 1 mS/cm could thus be obtained. SOLVAY has developed a synthesis route at large lab scale by using specific equipment to achieve the synthesis of sulfides showing optimal conductivity value and phase purity. Now the processes have been upscaled to reach the 10 kg scale.

Milestones

By now, a total of six milestones have been completed.
The next milestone is:
– the delivery of materials at kg scale.

Conferences & Events

During the third quarter of 2023, SUBLIME was presented at several conferences, workshops, and other events.

SUBLIME @ ECS244th Meeting

Ömer Ulaş Kudu (TNO) presented SUBLIME results related to the lithium metal interface with sulfide and halide solid electrolytes for solid-state batteries during the 244th ECS Meeting in Gothenburg, Sweden from 8th to 12th of October, 2023:

• Forming Artificial Solid-Electrolyte-Interfaces between Lithium Metal Anodes and Halide and Sulfide Solid Electrolytes in All-Solid-State-Batteries Via Spatial-Atomic-Layer-Deposition (Ömer Ulaş Kudu / TNO, oral presentation)

SUBLIME @ LC BAT1 2019 cluster event

The Innovation and Networking days on All-Solid-State Battery Technologies were held on the 27th and 28th of September 2023 at @CEA Minatec in Grenoble, France.

This meeting was a great opportunity to hear the latest innovations and technologies from the Battery Alliance and industry speakers (materials, manufacturing and end-users) and to gain insight into all the H2020 projects within the LC-BAT1-2019 cluster, i.e. @SUBLIME, @ASTRABAT, @SAFELiMOVE and @SOLIDIFY.

Arash Payandeh from FEV as project coordinator gave an overview on the project and took part in the discussions with stakeholders from industry, whereas Artur Tron (AIT) presented results related to the fabrication and processability of solid electrolyte and cathode films for sulfide solid-state battery,

• Sulfide electrolyte dry and wet chemical processing for all-solid-state batteries (Artur Tron / AIT, oral presentation)

Upcoming Events

The 8th General Assembly Meeting will be hosted in Braunschweig, Germany from the 29th to 30th of November 2023 by our colleagues from IST/TUB. Current results and upcoming tasks will be discussed and new strategies towards our goals will be developed.
