New battery with CO2 + Lithium: 7x more capacity

[jean.caissepas]

Hello,

New innovation to report:

https://dailygeekshow.com/batterie-co2- ... n-lithium/

To see if it will come out one day ...

Interesting but:

"Our unique combination of materials helps create the world's first carbon-neutral carbon-dioxide battery with much more power and battery life, which will allow it to be used for advanced energy storage systems Says Amin Salehi-Khojin, associate professor of mechanics and industrial engineering at the University of Illinois.

In other words it will be very expensive, reserved for high technology, space or medical genre ...

So do not hope too soon roll with batteries that capture the CO2 air ... which would be a shame !!

Last year they had arrived at ten charge / discharge cycles ... https://www.futura-sciences.com/science ... co2-72947/

The Massachusetts Institute of Technology (MIT) researchers' idea is to capture the CO2 directly when it leaves the factory. This is pre-activated with an aqueous solution of amines. These amines are not lost in the operation and can be reinjected continuously. By reacting with lithium, the carbon dioxide is then converted to lithium carbonate (Li2CO3). © MIT

... today 500 cycles

They leave the labs and have yet to go through the industrialization phase. But presumably by 18 months, we should have the first devices. So remember, these are carbon dioxide batteries. https://www.europe1.fr/emissions/L-inno ... pt-3923199

So do not hope too soon roll with batteries that capture the CO2 air ... which would be a shame !!

The trees are CO2 batteries.
The roofs are to disappear.

Yes 10 cycles it was indicated in the 1er article ... 10 cycles it is a pile it is not a battery!

I did not understand the graph ... without unity, rude ... not very scientific for something from MIT ...

There are 2 main physical quantities that determine (the efficiency of) a battery:

- The mass capacity in Wh / kg (possibly volume capacity)
- the mass power in W / kg or in W / Wh

None of the 2 is clearly stated in these articles, this passage is not very clear:

That is, for the same volume, considering that there is no energy loss, this battery could develop 7 times more energy than other batteries - or for the same power, have a battery life seven times higher.

But we can certainly draw the mass capacity of the graph ... provided we know how to decipher it!

Obviously to these 2 sizes must be added the price ...

It is well noted

This new battery already offers a tension and a competitive capacity. For now, its life does not exceed the 10 charge-discharge cycles.

The diagram shows the battery on the right and the carbon recycling circuit on the left.
In the new version:

It involved integrating molybdenum disulfide nanoflocks into the cathode catalyst and using a new type of hybrid electrolyte composed of ionic liquid and dimethylsulfoxide.
A combination of high efficiency
According to the researchers, this combination produces a battery made of several components rather than individual products, which allows to naturally integrate the carbon in the recycling process rather than forming a disturbing accumulation on the catalyst of the battery. This combination is so effective that they can reload their prototype 500 consecutive times. https://technologiemedia.net/2019/09/30 ... hargeable/

For 7 times it is poorly specified indeed.

500 times it gets interesting ... lots of drums do less than 500 real cycles ...

See now the cost of technology CO2 lithium ...
