Plan to commercialize supercapacitors in the next few years
concrete seems to be used here for its structural properties, just like we do it today. Their solution doesn’t seem to require it:
If more powerful capacitors are required, they can be made with a larger concentration of carbon black, at the expense of some structural strength. This could be useful for applications where the concrete is not playing a structural role or where the full strength potential of concrete is not required. For applications such as a foundation, or structural elements of the base of a wind turbine, the “sweet spot” is around 10 percent carbon black in the mix, the team says.
If it’s just a byproduct of other industries, like existing coal power plants, it might be seen as carbon neutral. And lithium batteries also use it.
