Cement is also not a good material, cement production accounts for 4-8% of all CO2 production.
I thought that was concrete?
Comment on YSK: You can make supercapacitors out of cement, water and carbon black

Cement is one ingredient in concrete, the other is sand and aggregate, which just require access to really.

I think the goal is to use it for the concrete slabs that form the foundation of every building. So, no extra material added, but only applicable for new buildings. No extra rare earth mining needed either. I think it’s pretty cool, and we should know about that possibility.
A “green” house could have that in the foundation and a solar roof and be nearly self sufficient.

A couple of guys doing cool stuff in a lab is how progress is made. If we stopped people like Tesla, Newton, and Faraday because “candles are readily available and whale oil is a natural resource” we wouldn’t have any of the tech we take for granted today.
This discovery is super cool, like imagine its applications in walkable cities where the entire pedestrian pathway is also storing energy from wind and solar

Concrete has different spec ratios, spec a higher psi concrete, and allow the lower end strength.
Commonly done when you want to use accelerators or retardants already.

You should probably stop trying to speak authoritatively on a subject you clearly know nothing about.
