8.1 : Study of the potentially most appropriate processes, involving
a range of techniques from the least costly but yielding the lowest
quantity of recycled material up to the most expensive process (cell
de-activation + mechanical separation+ agglomeration before pyro-metallurgical
or hydro-metallurgical treatment), yielding the most
usable material.

Milestone plan
Kick-off
AMENDMENT
* Delay of 9 -12 months to deliver cells according the technologies (selection of
materials longer than expected, delay of raw materials supply from Japan, change
of production site for LFP…)
* Problem of process for LMO (only 50 cells available) and NMC (2 batches were
necessary)

17. Exploitation potential
HELIOS results would influence the choice and the
integration of the best technologies on reliable,
safe, cost and recyclability points of view, in
vehicles (VE, PHEV) or trucks (HEV-APU) that will
contribute to reduce the CO2 emissions.
Specification of Common European procedures
(Cycling safety) for High Energy Li-ion batteries
inputs in European standards.
