Participants of the Month 12 Meeting at CIDETEC San Sebastian October 18.-19.2018.
Month 12 meeting in San Sebastian (ES)
On October 18th to 19th 2018 the IMAGE consortium held its month 12 meeting in San Sebastian, hosted by CIDETEC (www.cidetec.es). The Meeting included the visit of the CIDETEC high-tech battery labs from basic research of next generation battery materials to lithium-ion battery cell pilot production.
The overall project status was discussed and the next steps were jointly defined.
Main topics of the meeting were:
• Defining and finalizing of high-level industrial cell specifications and requirements for advanced EV-Battery (BMW) and performance-improved stationary energy storage (VARTA Storage).

• Development of cell chemistry, in particular research and production of high energy materials:
- Lithium metal anode: Extrude thin Li-metal film (Hydro Quebec). Develop lamination step for further reduce of thickness.

- Stabilizing of extruded thin Lithium metal fil by surface treatment (artificial SEI) with appropriate composition (Hydro Quebec).
- Combination of surface treatment and gel polymer electrolyte (ARKEMA, CIDETEC) are extremely important for the morphology of the lithium deposit and SEI structure for long cycling performance of lithium metal anode.
- Developing high-energy cathode electrode (water-based formulations) and electrolytes (CIDETEC, UMICORE, ARKEMA).

Furthermore, results of the following work were discussed and next steps agreed:
• Innovative method for investigation degradation on next generation Li-metal battery cell (ISEA).
• Solid battery concept development (CIC energigune).
• LMPB Cell prototyping (CIDETEC).
• Assessment of the impact of future LMPB cell technologies on module and pack concept (AVL).
• Developing validation models for next LMPB generation (VUB).
• Dissemination plan (VMB).
