Innovative Silicon and Lamellars for Li-ion battery – SILMARILION

The project SILMARILION aims at demonstrating a set of battery components suitable for 700Wh/L cell, using the following full cell
level approach:
-New cation-deficient Li-rich positives, targeting a specific capacity >= 250mAh/g
-µm-size Silicon from low cost milling, blended with graphite to achieve an electrode with > 1000mAh/g
-screening of electrolyte components and assess interface with active materials
-focus on electrode formulation in order to determine the more suitable set of binders and conductive additives
-correlate the complete cell properties to active materials & interfaces ageing, thanks to advanced characterization techniques such
as NMR and EELS (i.e. highlight the importance of full cell configuration vs half-cell).
-Demonstrate the achievements at prototype level with 3 generations of 18650-like cells, in order to reach a durability target of 20%
energy loss after 1000 cycles at C/2 at room temperature and 20% energy loss after 400 cycles at 45°C.
-explore some power/energy ratios.
