Hi everybody, Flavia speaking!
First, I would like to know a bit more about yourself: Do you own a hybrid or electric car?
Electric cars are indeed an interesting topic but maybe a bit controversial. As you may know, the strict environmental regulations are growing every day…… in order to reduce CO2 emission by 40% by 2030 within the EU.
The integration of a battery might be a solution, although further improvements are still needed: Driving range because, be honest, no one wants to be stranded on the motorway.The charging time, because no one wants to wait 8 hours to drive, Cost, because we are not millionaires and safety because we don’t want our car to explode!
So, up to date, lithium ion has been installed in hybrid or electric cars which has been a success but still presents major drawbacks such as thermal security, driving range and self-discharge.
Therefore, to find a safer system, one could think about lithium sulfur battery,which last year, thanks to the ALISE project, achieved the first battery pack of lithium sulfur tested by SEAT.
This battery, although being a great success, contained liquid electrolyte presenting security issues.Therefore, we aim to improve the lithium sulfur battery by changing the liquid electrolyte by a solid electrolyte. And, why would we do that?
Due to: The low cost of sulfur, 50 dollars per ton. It is environmentally friendly. It has a high energy density. There are no critical raw materials. It is thermally stable. No explosion after cycling nor high temperatures. No self-discharge. It is lighter than lithium ion.
Stop!! Come on!! WOW! This battery has a lot of advantages!
So, imagine the impact if we reach the good performance with the corresponding materials?
Therefore, thanks to the LISA project, we aim to reach more than 400 Wh/kg and 700 Wh/L, where large companies like Renault, Varta and VDL are working together and will be the first beneficiaries of this technology to be integrated not only in electric cars, but also in electric trucks and buses.
