Project objectives
The 3 year project objectives consist in the realisation
of a 1.35 kWh - 3 V - EV Lithium battery prototype
integrating:
- a specific 3 V Mn-oxide as a high capacity cathode
material
- an innovative technology already developed by the
battery manufacturer partner, and able to ensure the
highest level of safety compared to all other liquid
electrolyte systems
- a battery management system (BMS) providing high
cycling performances
The project is based on the following postulates:
1) for reasons of cost and toxicity, no other
intercalation compound than Mn-oxide based materials will
fit with EV targets.
2) It is our belief that 4 V liquid or half-liquid
systems cannot comply with safety constraints of EV,
although they may be well suited for portable
applications: electrolytes working at 4 V are highly
unstable, as soon as a local temperature or a local
voltage rises occur, and may reveal dangerous for EVA.
Experience shows that 3 V systems are by far less
sensible to local variations than 4 V systems. Their
thermal and electrical management will be easier in order
to guarantee the long-term (600 to 1000 cycles) cycling
stability.
3) V Mn-oxide based materials, up to now mainly known for
their poor energy density and lack of reversibility,
present now reversible capacities as high as 170 mAh/g.
Technical objectives:
- energy density (module): 120 Wh/kg-145 Wh/l
- sustained specific power/ impulse specific power during
30 s: 150 W/kg-250 W/kg
- number of cycles at 80% DOD: 600
- operating temperature range: -30 8C/+65 8C
- cost (module): < 150 ECU/kWh
- scale-up and demonstration runs of a 1.35 kWh battery
including a management system
These target performances will be achieved following
three stages (A,B,C) of development:
A (18 months): manufacturing of a 15-Volts/5Ah to 20 Ah
module with 1st version (A) of BMS
B (24 months): manufacturing of a 30-Volts/ 20 Ah to 30
Ah module with 2nd version (B) of BMS
C (30 months): manufacturing of a 1,35 kWh (45-Volts/30
Ah) module.
