A nice and ecological discovery that may be able to advance electric transport:

It would be cool if that isn't a new ad effect yet. To be continued.

No trace of the study found.
On the other hand a Chinese study https://www.sciencedirect.com/science/a ... 3X20301434
The optimized porous carbon has a high specific surface area of ​​1715,3 m 2 g −1 and a total pore volume of 0,6392 cm 3 g −1, with a unique hierarchical architecture and an ultra high content of 45,97 at% O self-doped and 0,49 at% N. When used as electrode materials for supercapacitors, the porous carbon prepared exhibits excellent specific capacity and energy density as well as fantastic cycle stability. Under a current density of 0,5 A / g, the electrode made from this material showed a high specific capacity of 530 F / g, with fantastic rate performance of 258 F / g at 20 A / g and excellent cycle stability of 91% capacity retention for 10 cycles at 000 A / g in a 10 M KOH three electrode system ...
From there to industrial manufacture what is the length of the step to take :?: We do not know :P

The unit in Farads / g does not speak to anyone ... What are the mass capacities in Wh / kg please and in Wh / L?

Super condos are still very far from the best lithium batteries ... from memory it is of the order of lead ...

It's in the summary, it depends on the technology used to build the condo
In the assembled supercapacitors, the electrode-based SF-PC 700-3 worked under a potential of 1 V and exhibited 222 F / g of specific capacitance at a current density of 0,5 A / g, and even when the density current was increased to 30 A / g, the specific capacity can still 168 F / g, verified the excellent performance of the SF-PC 700-3. The symmetrical supercapacitors in the electrolyte Na 2 SO 4 and TEABF 4 / AN showed voltage ranges of 1,8 V and 3 V respectively, and a high energy density of 22,2 Wh Kg -1 at 448. W Kg -1 and 40,6 Wh Kg -1 at 755,8 W.

We immediately see that we are dealing with an “expert” : Cheesy:
