Newsletter #3 / July 2023Summer is here and many colleagues are taking some time off for recreation, spending time with their families and getting a moment of tranquility in an otherwise rushing world.
Before leaving for a short summer break, we want to share with you the latest updates from the SUBLIME project.

Deliverables D4.4, D4.5, and D5.2, D5.3 – pouch cell design and manufacturing of lab-scale pouch cells The deliverables… - D4.4 – Report on layer processing towards upscaling - D4.5 – Report on monolayer pouch cell assembly - D5.2 – Report on prototype cell design - D5.3 – Results of the process upscaling benchmarking for cathode and solid electrolyte layer …have been submitted. These four documents summarize our efforts towards scaling of the sulfide-based all-solid-state battery manufacturing and processing steps and include the cell design for the final demonstrators. Some highlights of the deliverables are given below: |
D4.6 – interface characterization The deliverable D4.6 - Report on solid-to-solid interface characterization reports on the characterization of the different interfaces in the SUBLIME all-solid-state battery cell. Interfacial resistances between the different layers of the battery cell have been identified as one of the major bottlenecks for proper electrochemical performance; they can be caused by several phenomena, including lack of contact and formation of highly resistive interphases. Therefore, an extensive experimental study has been conducted to identify the underlying mechanisms of interfacial resistances and to develop strategies to overcome them. |

D7.2 mechanism Li transport Li transport on the anode side is highly important for realizing Li-metal batteries for increased energy density. D7.2 - Mechanism of Li transport and dendrite formation in all solid battery summarizes our activities in this field by physics-based multiscale modelling. Li dendrite formation and propagation has been modeled in Argyrodite electrolytes and the effect of temperature and current density has been investigated. |

Milestones One milestone, i.e. assembly of pouch cells (up to 40 mAh), was reached after submission of D4.5. By now, a total of six milestones have been completed. Upcoming milestones include |
|
Major results so far New generation of sulfide-based solid electrolyte A new generation of the sulfide-based solid-electrolyte has been developed with approx. twice the ionic conductivity compared to the previous generation. This material will advance our efforts to develop high power battery cells, which rely on high ionic conductivities for low internal resistances, especially at high current densities.

Upcoming Events It is going to be an exciting autumn and winter 2023/2024 and we look forward to meeting our colleagues and supporters around the world at some of the long-awaited upcoming events.
- Save the date – the Innovation and Networking days on All-Solid-State Battery Technologies will be held on the 27th and 28th of September 2023. This joint event brings all projects funded under the Horizon 2020 Program LC-BAT-01-2019 together in a hybrid meeting (face-to-face & online). It will be open to everyone from academia to industry. The event venue will be at @CEA Minatec in Grenoble, France. In this meeting, you will have the opportunity to hear the latest innovations and technologies from the Battery Alliances and industry speakers (materials, manufacturing and end-users) and learn more about the H2020 projects, i.e. @SUBLIME, @ASTRABAT, @SAFELiMOVE and @SOLIDIFY. The agenda has been set up and can be found here https://sublime-project.eu/wp-content/uploads/2023/06/AST-final-event-agenda.pdf |
