It is a cement-based battery made by researchers at Chalmers University of Technology in Sweden.

In particular, they combined a mixture of cement with carbon fiber to improve its electrical conductivity and structural strength. A metal-coated carbon fiber frame was incorporated into the mixture, helping to move the electrons.

Of course, energy density is quite low when compared to commercially available batteries, just 7Wh per square meter, but researchers believe that if we use the technology in a large enough volume, such as that of a building, the limitations will be overcome.

Researchers hope that if cement is used extensively in building construction, buildings that incorporate this technology will be able to store energy and become energy independent. They will be able to power the LED lighting, offer 4G connections in isolated areas without access to electricity and in addition offer corrosion protection.

The team recognizes that the project is in its early stages of implementation and has important issues to address, such as extending the battery life cycle and developing recycling techniques.
