The objective of the project is to develop an all-solid-state Li-ion battery for Electric Vehicles with the following characteristics:
1 ―
Anode-free system
No graphite, no lithium metal or other anode material, “only” a tailored current collector that enables the stripping/plating of the Li ions contained in the electrolyte → more 100% of volumetric energy density.
2 ―
3D printable
Unconventional manufacturing via Vat Photopolymerization 3D printing avoiding solvent drying, recovery, formation and degassing steps → up to 64% less energy needed for the battery manufacturing
3 ―
Targeted KPIs
→ 400 Wh/kg and 1000 Wh/L
→ 3-Ah cell prototypes
→ 3000 cycles
→ Charge capability of 70% of its total capacity in 5 minutes
