1. Robust binder system developed
and able to handle large volume
expansion/contraction
2. Do not expect cycle life limitation
from cathode being detached from
the current collector
3. Cycling at 80% DOD lead to high
cycle life until electrolyte is
depleted
4. Surface capacity needs to be
higher than 4mAh/cm² for energy

Objective #2 – Safe and High Energy density LiS cell:
500 Wh/kg, 250 W/Kg (C/2), 2000 cycles
1. New chemistry is attempted for ALISE project, with new electrolyte and with
metallic lithium for the anode without protection at module level
2. Jully 2017, thermal assessment is closing the safety tests campaign. Issues are
detected for short circuit test and thermal test before 60ºC (self heating, swelling).
3. Venting, electrolyte expulsion, cell rupture and fire are observed only after 160ºC
4. >72% of the C/5 capacity at 2C (our objective is 75%)
5. Metallic lithium for pouch cell up scaling production an module level
(i.e. hundreds layers for pouch cell, 82 cells per module)
6. Protected lithium for final cell at pouch cell level aiming to tackle anode electrolyte
interface issue and reaching higher number of cycles
7. Cylindrical format is explored in the framework of ALISE
Pouch Cell
May 2017, hundreds of 300 Wh/kg, 230 Wh/L, 12.5 Ah pouch cells have been produced

Objective #3 – Usable technology:
SoC, charging and discharging model, sensoring
Challenges
1. Coin cell results cannot be extrapolated to pouch cell
2. Cell manufacturing must to be advanced enough (TRL4-6) and built from advanced materials (TRL6)
3. Lithium Sulphur charge and discharge profile curves are changing within:
• The intensity of current applied
• The temperature
• The number of cycles (aging)
Work on going on real breakthrough to make the cells usable for electrical car
1. Algorithmic to traduce the chemical behavior to electronic control (SoC for charge and discharge)
2. Hardware and software development dedicated specifically to Lithium Sulphur technology (CMC, BMS)
3. Innovative printed sensor to track deformation and cell temperature

Objective #4 – Integration
module, 17 KWh battery pack, behaviour for PHEV targeting 100 Km electrical driving range
The results
November 2017, first module for PHEV is built with 82 Lithium Sulphur cells (41s2p)
1. Highly challenging to make fitting the LiS technology conserving the same battery pack housing layout used for
Lithium ion (volume and shape)
2. Design is achieved including cooling system and interface (mechanical and electrical)
3. 1D analysis of coolant system design is completed
4. Change at battery pack level to release more volume and to avoid any interferences
Our next step
1. Module fixing – final review
2. Feedback from build of first module
3. Cooling system optimization based on more accurate data
4. To asses all safety test at module level (electrical, mechanical, thermal) and feedback associated
5. Revised manifold design
